This yields correct C++ semantics, and + preserves the location information, which has the nice effect + that &(&R) given the location containing R. + * values.c (value_copy): Make non-static (used by value_addr). + * eval.c (evaluate_subexp_for_address): Use the default + scheme (with value_addr) for a variable if it has TYPE_CODE_REF. + * valops.c (value_addr), eval.c (evaluate_subexp_for_address, + evaluate_subexp_with_coercion): Factor out some common + expressions into variables, for easier reading. + * findvar.c (locate_var_value): Remove code to handle + TYPE_CODE_REF - it should no longer be needed. + * valops.c (value_assign): Do a COERCE_REF on the + destination operand, for correct C++ semantics. + * valarith.c (value_x_binop): Ditto: De-reference C++ + references in the arguments. + * valops.c: ANSI-fy: bcopy->memcpy, bzero->memset. + +Sat Dec 28 11:30:26 1991 Per Bothner (bothner at cygnus.com) + + * dwarfread.c, coffread.c: Use INIT_CPLUS_SPECIFIC. + * symtab.c (gdb_mangle_name): Recognize and handle + constructors specially. + * symtab.c (check_stub_method): Test for failure from + cplus-demangle by calling error() instead of seg-faulting ... + +Fri Dec 27 22:21:30 1991 Fred Fish (fnf at cygnus.com) + + * defs.h: Add definition of null_cleanup() + + * procfs.c: Many small changes to add base support for a new + "info proc" command (currently only printing of the address + space mapping is implemented) and allow iteration over the + address space mapping, calling an arbitrary function for each + mapping (used for shared library support). + + * solib.c: Change all ifdefs that checked for "sun" to check + for "!SVR4_SHARED_LIBS" instead. Rewrite lookup_base() to + handle locating the debug base address even when not currently + stopped at the dynamic linker entry point. + + * utils.c: Add null_cleanup() as a known function that does + nothing to serve as a base for possibly long cleanup chains + with no specific "first cleanup" to serve as an anchor. + + * xm-sysv4.h: Add define of SVR4_SHARED_LIBS + +Fri Dec 27 10:11:33 1991 Per Bothner (bothner at cygnus.com) + + * arm-opcode.h, m88k-opcode.h, pn-opcode.h, np1-opcode.h, + pyr-opcode.h, tahoe-opcode, vax-opcode.h: Removed - + these are all essentially the same as the versions + in ../include/opcode. The remaining *-opcode.h here + are not quite so obviously the same, and need study. + * arm-pinsn.c, gould-pinsn.c, m88k-pinsn.c, pyr-pinsn.c, + tahoe-pinsn.c, vax-pinsn.c: Change so these include + opcode/FOO.h (actually ../include/opcode/FOO.h) + instead of the recenntly departed opcode-FOO.h files. + * sparc-pinsn.c: Now that we're using the much tighter + opcode table in ../include/opcode/sparc.h, we shouldn't + need to sort the opcodes before dis-assembly. + + * symtab.h, symmisc.c: Make cplus_struct_default be const. + * symtab.h, buildsym.c: Add and use INIT_CPLUS_SPECIFIC macro. + * symmisc.c: Remove unused 'nfields' variable. + * buildsym.h: Add extern decl of unknown_symtype_complaint, + since it used used by partial-stab.h (included two places). + * partial-stab.h: Re-arrange DBXREAD_ONLY #ifdefs so that + we should never hit the default case (until new stab codes + are added). Hence, we can leave the complaint in the + default case in even when DBXREAD_ONLY is off. + * partial_stab.h: Recognize a pair of N_SO stabs (one for the + directory, one for the filename proper) without peeking ahead. + * dbxread.c, mipsread.c: Because of previous change, don't need + ugly CHECK_SECOND_N_SO macro. + * buildsym.h, dbxread.c, mipsread.c: Make next_symbol_text a + macro that invokes a function pointer in next_symbol_text_func. + * mipsread.c: Added comments various places to + explain what is going on. + * mipsread.c (parse_symbol): Support the new (SGI-specific?) + symbol types stStruct, stUnion, and stEnum. + Also, some fixes in the code for dealing with tags. + * mipsread.c: Change handling of startup_file_start and _end + - now just use the textlow and texhigh of a psymtab + to check if we've found the startup-file. + * mipsread.c: Replace s_idx by global cur_sdx in many places. + This is so mips_next_symbol_text can get at it. + +Thu Dec 26 19:52:01 1991 Fred Fish (fnf at cygnus.com) + + * dbxread.c, symmisc.c: Move add_psymbol_to_plist() from + dbxread.c to symmisc and change name to add_psymbol_to_list. + Ditto for add_psymbol_addr_to_plist(). Also expand their + body to not use ADD_PSYMBOL_VT_TO_LIST. + + * dwarfread.c: Remove add_psymbol_to_list() and convert usages + to the ADD_PSYMBOL_TO_LIST macro. + + * ieee-float.c: Change "#ifdef DEBUG" to "#ifdef IEEE_DEBUG" + to avoid collision with the DEBUG for ADD_PSYMBOL_VT_TO_LIST. + + * partial-stab.h, symfile.h: Move definitions of the macros + ADD_PSYMBOL_TO_LIST and ADD_PSYMBOL_ADDR_TO_LIST from + partial-stab.h to symfile.h. They aren't stab specific. + Change ADD_PSYMBOL_VT_TO_LIST to use memcpy rather than strncpy. + +Tue Dec 24 11:38:08 1991 John Gilmore (gnu at cygnus.com) + + * Makefile.in: Roll VERSION to 4.3.2. + +Mon Dec 23 13:54:35 1991 Per Bothner (bothner at cygnus.com) + + * m68k-opcode.h, mips-opcode.h, sparc-opcode.h: Deleted. + * m68k-pinsn.c, mips-pinsn.c, sparc-pinsn.c: + Include <opcode/FOO.h> instead of <FOO-opcode.h>. + + * symtab.h, symtab.c, coffread.c, dwarfread.c, symmisc.c, + dbxread.c: The TYPE_CPLUS_SPECIFIC structure is now only + allocated when it is needed. Until it is needed, it points + to a shared statically allocated structure. + + * buildsym.h, buildsym.c, dbxread.c: Remove the kludgy code + in read_ofile_symtab to recognize two initial N_SO stabs, + and let process_on_symbol handle it. This is cleaner, more + efficient, and lets mipsread.c share the same code. + + * symfile.h, partial-stab.h: Move ADD_PSYMBOL_VT_TO_LIST + and related macros to here ... + * dbxread.c: ... from here. + * symmisc.c: Move the "overflow" handling from + ADD_PSYMBOL_VT_TO_LIST macro into new function extend_psymbol_list. + * dwarfread.c: Re-write add_psymbol_to_list to use + ADD_PSYMBOL_VT_TO_LIST macro. + + * mipsread.c: Extend mipsread.c to handle stabs-style symbols + encapsulated in ecoff symbols. This enable full g++ debugging. + * partial-stab.h: Move the code for pre-scanning symbols + and building psymtabs to an include file, out from dbxread.c. + This way, the same code can also be used by mipsread.c. + * dbxread.c, buildsym.h: Various changes to allow some functions + to be used by mipsread.c (also some arguable stylistic changes). + + * tm-mips.h: Define BLOCK_ADDRESS_ABSOLUTE, at least for now, + since mips-tfile puts relocatable addresses into LBRAC/RBRAC + stabs. + + * mipsread.c: Replace code to handle ambiguous tag blocks. + Instead of allocating a TYPE_CODE_UNDEF, guess (by looking + at types and offsets) if a tag is a struct, union, or enum. + Still patch it later if we find out for sure. + * mipsread.c: In various ways, replace Forin's + ideo-syncratic code by code that fits better with the + rest of gdb, for both stabs-based and ecoff-based symtabs. + E.g. use end_psymtab; don't do extra passes over FDR table to + pre-partition global data; don't use external symbols to + create static/global symbols (just put them in the + misc_vector); use ADD_PSYMBOL_TO_LIST macro; don't + sort psymtabs or symtabs; use obstacks more. + + * symtab.c, mipsread.c, dbxread.c, buildsym.c: + ANSIfy: Replace bcopy by memcpy, bzero by memset. + +Sun Dec 22 19:31:04 1991 Fred Fish (fnf at cygnus.com) + + * solib.c (locate_base): Fix uninitialized variable that was + causing return of random value to callee. + + * config/mh-amix, config/mh-i386v4: Change to find alloca by + compiling and linking alloca.c, even when it is not strictly + required. Also arrange to link with -ltermlib rather than + -ltermcap. + + * Makefile.in: Move TERMCAP definition to prior to inclusion + of host makefile fragments so it can be overridden. + +Fri Dec 20 16:33:39 1991 John Gilmore (gnu at cygnus.com) + + * xcoffread.c (read_symbol_lineno): Logic error in incrementing + symbol table entry number. (From Metin Ozisik.) + +Fri Dec 20 11:36:38 1991 Fred Fish (fnf at cygnus.com) + + * config/mh-i386v4: Change XM_CLIBS to "-lc /usr/ucblib/libucb.a" + so compiles with native compilers (without builtin alloca) can + pick up the version from the bsd emulation library. However, we + search the standard C library first so we don't pick up lots of + other broken stuff from libucb.a, that we *don't* want. + + * configure.in, tm-amix.h, tm-i386v4.h, xm-amix.h, xm-i386v4.h: + Change svr4 references to sysv4. + + * source.c: Move declaration of external function index to + front of file so it is in scope for all references. + + * utils.c (error, fatal): Make definitions consistent with + defs.h declarations (declared as "volatile void"). + +Fri Dec 20 10:55:36 1991 John Gilmore (gnu at cygnus.com) + + * rs6k-opcode.h: Bugfix sfe and stbrx. By Al Kossow. + +Wed Dec 18 17:09:06 1991 Stu Grossman (grossman at cygnus.com) + + * command.h, defs.h, eval.h, expression.h, remote-sa.sparc.c, + sparc-tdep.c, symtab.h, target.h, value.h, vx-share/ptrace.h, + vx-share/xdr_ptrace.h, vx-share/xdr_rdb.h: ANSIfy enums. + +Mon Dec 16 12:31:46 1991 Fred Fish (fnf at cygnus.com) + + * config/mt-amix, config/mt-i386v4: Add solib.o to TDEPFILES + for these SVR4 systems. + + * symfile.c (symbol_file_add): When verbose is set, print + the names of files from which symbols are being loaded, as + when from_tty is true. + + * solib.c: Completely reorganized (rewritten) to support + SVR4 shared libraries in a manner very close to the original + SunOS implementation. This support is expected to change and + become more general at some future time. The SVR4 version + does not yet work for attached processes, for example. + + * dwarfread.c: Arrange in dwarf_build_psymtabs() for the + relocation address to be valid whether or not symbols are + being read from a shared library or an executable. Use the + relocation address recorded in the psymtab when reading + full symbol tables (in read_ofile_symtab). Ensure that the + relocated address ranges are recorded in partial symtabs. + + * elfread.c: Add new function elf_interpreter() to return the + string from the ELF ".interp" section. This is the interpreter + that the kernel tries to run and feed the executable to. + Expand arguments to record_misc_function to include a type arg. + Modify elf_symtab_read() to supply the type arg, and to do symbol + relocations for symbols read in from shared libraries. + + * procfs.c: Add new functions proc_base_address() and + proc_address_to_fd(), used by shared library support. + + * tm-svr4.h: Add macros to support SVR4 shared libraries. + Definitions for SOLIB_ADD, SOLIB_CREATE_INFERIOR_HOOK, + CLEAR_SOLIB, and DISABLE_UNSETTABLE_BREAK. + +Fri Dec 13 20:11:26 1991 John Gilmore (gnu at cygnus.com) + + * infrun.c, remote-eb.c, remote-nindy.c, remote-vx.c: Remove + unused START_INFERIOR_HOOK. + + * remote-eb.c: Change timeout to 24 seconds (*10 fits in byte) + to account for slow loading from floppies. + (eb_create_inferior): New fn, from eb_start and + nindy_create_inferior. + (eb_close): Only use log_file if nonzero. + (eb_xfer_inferior_memory): If not writing, then read! + (eb_read_inferior_memory, eb_write_inferior_memory): Return length. + (eb_kill): A new no-op. + (eb_mourn_inferior): Remove breakpoints, then generically weep. + +Fri Dec 13 16:09:23 1991 Fred Fish (fnf at cygnus.com) + + * breakpoint.c, findvar.c, infrun.c, putenv.c, stack.c: Fix + miscellaneous comparisons of integer with NULL that elicit + compiler warnings about comparison of integer with pointer, when + NULL is ((void *) 0) rather than just a bare 0. + +Wed Dec 11 13:02:58 1991 John Gilmore (gnu at cygnus.com) + + * breakpoint.c (breakpoint_re_set_one): Disable each breakpoint + while we reset it, in case of problems. Print breakpoint number + in error messages. + + * buildsym.c (read_struct_type): Avoid sun3 compiler bug with + foo[--n]. + + * source.c (find_source_lines): If getting file mod time fails, + don't warn. + + * target.c (target_xfer_memory): If errno is set, return it, + rather than EIO. + +Tue Dec 10 04:07:22 1991 K. Richard Pixley (rich at rtl.cygnus.com) + + * Makefile.in: infodir belongs in datadir. + +Sun Dec 8 21:13:33 1991 Michael Tiemann (tiemann at sphagnum.cygnus.com) + + * symtab.h (struct fn_field): Add new fields `is_private', + `is_protected', `is_stub', making room by reducing the size of + `voffset'. + (struct fn_fieldlist): Delete the fields `private_fn_field_bits' + and `protected_fn_field_bits'. + (TYPE_FN_{PRIVATE,PROTECTED}_BITS): Deleted. + (SET_TYPE_FN_{PRIVATE,PROTECTED}): Deleted. + (TYPE_FN_{PRIVATE,PROTECTED}): Deleted. + (TYPE_FN_FIELD_{STUB,PRIVATE,PROTECTED}): New macros. + * valops.c, valprint.c, symtab.c: All callers updated. + + * buildsym.c (read_struct_type): Delete the `visibility' field + from `struct next_fnfield', and rework code so that visibility + info is stored into the fn_field directly. Also, hacked to set + TYPE_FN_FIELD_STUB for both static and normal member functions. + +Sat Dec 7 18:13:11 1991 Fred Fish (fnf at cygnus.com) + + * i386-tdep.c: Fix a problem on i386 systems where buffered code + stream access was failing to take into account the minimum size + granularity of the code section. For now, the buffering is simply + disabled. There is a similar problem in the i386 disassember code + that has not yet been fixed (FIXME). + + * gmalloc.c: Use macros to hide some of the ugly casting required + in the previously applied fix for pointers with high bits set. + +Sat Dec 7 16:49:35 1991 John Gilmore (gnu at cygnus.com) + + * Makefile.in: Roll VERSION to 4.3.1. + +Sat Dec 7 04:12:35 1991 John Gilmore (gnu at cygnus.com) + + GDB-4.3 release! + + * Makefile.in: Roll VERSION to 4.3 + * README, TODO, WHATS.NEW, depend: Update. + + * inflow.c (terminal_inferior): Avoid error msg if attached. + + * gmalloc.c: Fix bug that causes malloc & free to + fail on systems where pointers have the high bit set (0x800efcf0 + for example). The problem is that the difference between two + pointers is a signed integer, so the computation + + (char *) 0x800efcf0 - (char *) 0 + + yields a negative value. The sign of the result of the modulus + operator is machine dependent for negative operands, thus it is + possible for it to end up negative. From Fred Fish. + +Sat Dec 7 00:00:15 1991 K. Richard Pixley (rich at rtl.cygnus.com) + + * Makefile.in: install using INSTALL_PROGRAM and INSTALL_DATA. + added clean-info. added some standards.text support and made it + look like our other Makefiles. + + * configure.in: mark this directory target dependent. configure + now runs entirely in objdir so make existence tests and + references against ${srcdir}. + +Fri Dec 6 08:30:36 1991 Fred Fish (fnf at cygnus.com) + + * dwarfread.c (enum_type, struct_type): Fixes for opaque and + anonymous enumerations, structures, and unions. Now passes all + the current gdb test suite tests. + +Thu Dec 5 22:46:13 1991 K. Richard Pixley (rich at rtl.cygnus.com) + + * Makefile.in: idestdir and ddestdir go away. Added copyrights + and shift gpl to v2. Added ChangeLog if it didn't exist. docdir + and mandir now keyed off datadir by default. + +Thu Dec 5 21:53:21 1991 John Gilmore (gnu at cygnus.com) + + * symtab.c (decode_line_1): If SKIP_PROLOGUE leaves us in + mid-line, be more careful about possibly advancing to the next line. + +Thu Dec 5 18:59:51 1991 Michael Tiemann (tiemann at cygnus.com) + + * cplus-dem.c (cplus_demangle): Call `string_need' when + null-terminating a partially-computed string. + +Thu Dec 5 18:19:43 1991 Fred Fish (fnf at cygnus.com) + + * dwarfread.c (enum_type): Build a correct TYPE_NAME, add a + symbol to the symbol table for each member of the enum. + + * dwarfread.c (struct_type): Build a correct TYPE_NAME. + + * dwarfread.c (add_enum_psymbol): New function to extract enum + member names and add them to the partial symbol table while + building partial symbol tables. + +Thu Dec 5 17:31:05 1991 John Gilmore (gnu at cygnus.com) + + * symtab.c (check_stub_method): Must allocate two extra argument + slots (one for `this', one for arglist terminator). + +Thu Dec 5 10:51:05 1991 Fred Fish (fnf at cygnus.com) + + * inflow.c (child_terminal_info): Supply missing '"' character. + + * buildsym.c (define_symbol): Supply missing parenthesis. + +Thu Dec 5 03:34:21 1991 John Gilmore (gnu at cygnus.com) + + * coredep.c (fetch_core_registers): Fencepost error. Fixed by + Jay Lepreau <lepreau@cs.utah.edu>. + + * inflow.c: Remember whether GDB has a terminal. Avoid switching + terminals back and forth if we don't have one. + + * c-exp.y (parse_number): Zero is not an unsigned int constant! + * dbxread.c (read_dbx_symtab): Enum type numbers can be in (1,2) form. + + Improve type parsing. + * buildsym.c (define_symbol, read_range_type): Add + long_kludge_name that passes the names of range types being + defined, down to where we must choose between 'int' and 'long' + variants. This fails on Sun C anyway since the compiler itself is + confused between int and long. + (read_array_type, cleanup_undefined_types): Correct the size of + array type whose element-type size isn't immediately known. + + Early preparation to blow away many builtin types, building them + on the fly as needed. Don't compare types to builtin types with + ==; examine the relevant fields instead. + * coffread.c (process_coff_symbol: C_ARG, C_REGPARM): Avoid ==. + * buildsym.c (define_symbol, case 'p'): Avoid ==. + * valops.c (value_arg_coerce): Avoid ==.

His ChangeLog + entries are enclosed herein. Not all of these changes + have been merged into the master GDB sources -- check the + ChangeLog above here for the merge log. + +Mon Jun 3 17:05:45 EDT 1991 + + m2-exp.y Created. Tested outside of GDB for a few days. Proper + operators were added, C specific operators and tokens + removed. yylex() revamped to some extent. Still things + missing from the grammar, such as sets. + Tested for two weeks in GDB v3.5. + +Tue Jun 11 17:23:48 EDT 1991 + + m2-exp.y Added boolean constants TRUE and FALSE to the grammar + so they are built-in. Sort of a hack. + +Fri Jun 14 12:53:51 EDT 1991 + + m2-exp.y Added range checking for numeric constants. Any numeric + constant is assumed to be of builtin type INTEGER unless: + (1) it is octal or hexadecimal, in which case it is a + CARDINAL; (2) it is too big to fit into an INTEGER, in + which case it is a CARDINAL. + eval.c Added simple range checking for +, -, and * on integers. + Doesn't work very well for *, since 6 * 1,000,000,000 = + 1,705,032,704, which fails the simple test of result >= + first_operand, no matter in what order the operands are. + +Tue Jun 18 14:11:30 EDT 1991 + + Broke the parser into parts, one containing the C grammar and the other + containing code to be shared by all of the grammars. + + The following files no longer exist: + + expread.y + expread.tab.c + + The following files were added: + + c-exp.y (The C grammar) + m2-exp.y (The Modula-2 grammar) + parser-code.c (Code that is shared by the above grammar) + parser-code.h + parser-defs.h + + Makefile.dist Changed to reflect the above dependencies. NOTE: It is + now necessary to use the Bison compiler compiler, since it + will generate function/variable prefixes other than yy. + +Tue Jun 18 16:47:49 EDT 1991 + + symtab.[ch] Added the external variable working_lang, than holds the + value of the current working language. + Added the ennumerated type language_mode, with the values + language_auto and language_manual, the former meaning that + GDB sets working_lang as needed, and the latter meaning + that the value of working_lang is totally under user + control. + symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL, + REAL, BOOLEAN and CHAR. Also added the type codes + TYPE_CODE_BOOL and TYPE_CODE_CHAR. + utils.c Added set_language_command and show_language_command to + implement the GDB support commands "set language" and + "show language". + expression.h A number of identifiers were added to the type exp_opcode + to facilitate Modula-2 builtin functions, integer + division, and array indexing. + +Wed Jun 19 13:25:58 EDT 1991 + + language.h Added the macro STRICT_TYPE, which evaluates to non-zero + if the language specified by working_lang requires the use + of strict typing of expressions. Eventually, even this + will be able to be changed by the user. + Added the macro RANGE_CHECK, which evaluates to non-zero + if the language specified by working_lang requires the + checking of a value against the domain of its type. + Eventually, even this will be able to be changed by the + user. + language.[ch] Predicates involving types (simple_type, ordered_type, + same_type, integral_type, numeric_type, character_type, + boolean_type, float_type) are added. These predicates are + based on the current value of working_lang, and are handy + in type-checking. + +Wed Jun 19 15:39:34 EDT 1991 + + eval.c Added the function type_array_rank which computes the rank + of an array type. + valarith.c Added the funtion value_bool, which when given a integer + value.h value (ie. struct value *) as an argument, it returns a + boolean value (ie. struct value *) true if that integer + is non-zero, and a boolean value false otherwise. + valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values + will print out properly. + +Wed Jun 19 16:36:34 EDT 1991 + + valops.c Added the function value_capitalize, which returns it + value.h argument capitalized if its argument is a lowercase + letter, or the argument unchanged if its argument is not a + letter. + valarith.c Added the function range_check_p, which returns non-zero + value.h if its value argument is between the integral bounds upper + and lower. + Added the function range_check_enum_p, which makes sure + that its value argument is a valid member of the domain of + its type argument. + Added the function range_check_range_p, which makes sure + its value argument lies between the upper and lower bounds + of its type argument, which must be a ranged type. + Added the function check_array_index, which range and type + checks an index of an array. + Added the function value_multi_subscript, which computes + array[idx1,idx2...idxN], given a value array and an array + of values representing indicies. + values.c Changed value_from_long to work with TYPE_CODE_CHAR and + unpack_long to work with TYPE_CODE_BOOL and + TYPE_CODE_CHAR. + +Wed Jun 19 18:04:08 EDT 1991 + + symtab.c Stored pervasive types in a structure and make + lookup_pervasive_type() a lookup function that was based + on working_lang. If lookup_pervasive_type() returned + non-zero, then that value was returned (a fix, since + before it simply wouldn't return the pervasive type.) + language.h Added the macro CAST_IS_CONVERSION, which evaluates to + non-zero if the language specified by working_lang means + "conversion" when it says "cast". + valops.c Added the function value_real_cast(), which performs a + value.h *cast*, not a *conversion*, which is what value_cast() + does when it can. In particular, + value_cast(<float_type>,4) = 4.0, while + value_real_cast(<float_type>,4) = some mess. + eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR, + parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL. + expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX + and MIN on integral types. *NOTE*: These are currently + hardcoded to work only if there are 8 bits per storage + unit. FIXME. + eval.c Made logical functions call value_bool to return a + properly typed boolean value, based on working_lang. + +Thu Jun 20 11:55:27 EDT 1991 + + valprint.c Types now print out in a Modula-2 fashion. This works for + the cases when the type is printed out step-by-step, that + is, it doesn't work when the name of a structured type + (which includes the keyword "struct", etc.) is simply + displayed. + FIXME: Perhaps this is bad. Parts of it seem to kludgey, + since type specifications in C and Modula-2 are very + different. The C printing of a type is very recursive, + whereas in Modula-2 it is generally very simple. C has + type prefixes and suffixes, which have no real analogue in + Modula-2. Maybe type_print() should call a language + specific type printer. This is also advantageous if we + compile GDB to exclude some of the languages. We'll just + leave those functions out. + +Thu Jun 20 16:57:10 EDT 1991 + + dbxread.c When reading the complete symbol table in (via + psymtab_to_symtab()), the number and types of function + arguments are added to a function type. define_symbol() + calls add_param_to_type() to accomplish this. + Assumption: when we come across a function definition + (N_FUN symbol with an 'f' or 'F' in the name), its + arguments will appear before another function definition. + When a function is found, a pointer to its type is placed + in the global in_function_type. Changes that + add_param_to_type() makes are to this global. + valprint.c The type of a function now includes (for Modula-2) the + types of its parameters. + eval.c Type checking and a check for the proper number of + arguments is now done for function calls. Not sure of the + impact this has on C++ member function yet. + +Thu Jun 20 19:58:48 EDT 1991 + + valprint.c Rewrote the type printer. Broke it into two language + specific parts, adding the functions type_print_m2() and + type_print_m2_1(). + An unfortunate consequence is this: if you debugging a C + program in Modula-2 mode (why?), info types does not work + well with regular expressions, since the types are printed + out in Modula-2 terminology, but stored in C terminology. + language.[ch] Added the functions new_type_last(), type_keyword(), and + type_sep() to aid in the printing of typedefs. + symtab.c Made the printing of typedefs as language independent as + possible through calls to new_type_last(), type_keyword(), + and type_sep(). + +Fri Jun 21 11:50:26 EDT 1991 + + dbxread.c Check all incoming ennumerated types. If it looks like + Modula-2's BOOLEAN type, then change the type_code of the + type to TYPE_CODE_BOOL so we can process it as a boolean + variable. + valprint.c Replaced some of the 0x%x with calls to sprintf and + hexformat() in val_print(). + language.[ch] Added the function hex_to_string(), which converts its + integral argument to a hexadecimal number (format is + language based) and returns the result as a string. + +Mon Jun 24 12:25:07 EDT 1991 + + valprint.c Some functions call type_print_1() directly, instead of + value.h using type_print(), so they can specify where (column) to + print things. Since type_print() takes care of language + dependence, that needs to be called first. Added a + parameter depth to type_print() (so it is now like + type_print_1). Changed type_print to type_print_at, and + made type_print a macro that passes a depth argument of + zero. + symmisc.c Changed all calls to type_print_1 to calls to + type_print_at. + Makefile.dist Made it possible to build GDB for a specific set of + depend languages. Do this by passing a definition for the macro + LANGS to make. LANGS should be a string containing a + space-separated list of language names (ie. LANGS="c m2"). + The default is to build all languages. Note that grammar + files must follow the naming convention of <lang>-exp.y. + gdb.lang This holds the current value of the LANGS macro. It is + examined every time make is called, and is updated if + necessary. + eval.c Added #ifdef _LANG_<lang> to these files. + expread.c Still need to add them to dbxread.c and coffread.c. + main.c + source.c + symtab.c + utils.c + valarith.c + valprint.c + +Mon Jun 24 16:33:11 EDT 1991 + + language.[ch] Added the functions hexformat_pre() and + hex_to_string_pre(), which take a prefix argument to + include in the format string. Thus, hexformat_pre("08") will + return "0x08x" (if the working language is language_c). + Made hexformat() and hex_to_string() calls to the above + with "" as the prefix argument. + + am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c, + dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c, + infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c, + mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c, + pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c, + stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c, + valprint.c, vax-pinsn.c + + Changed all occurences of 0x%[0-9]*l*x in printf format strings to + calls to hexformat() and hex_to_string(). Format strings without + the leading "0x" were ignored. + + depend Updated to take the above into account. + + +Tue Jun 25 15:27:18 EDT 1991 + + symtab.h Added the types range_mode_t, range_check_t, type_mode_t, + and type_check_t to keep track of the current state of + range and type checking. + main.c Added the variables range_mode, range_check, type_mode, + and type_check to record the current state of range and + type checking. Added initialization code to main(). + language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine + the above variables. + + +Tue Jun 25 17:57:08 EDT 1991 + + dbxread.c process_one_symbol() updates the variable (enum language) + source_lang based on the extension of the filename + contained in the N_SO sybmol that started this symtab. + When end_symtab() is called, the value of source_lang is + put into the language field. + stack.c select_frame() sets working_lang (and possibly type_check + and range_check) to the language field of the symtab + associated with the frame that is selected if working_mode + is language_auto. If working_mode is language_manual, a + warning is printed and working_lang is not set. + language.c Added the function set_type_range(), which sets the value of + type_check and range_check (if their modes call for + automatic setting) based on the current value of + working_lang. A non-zero argument will cause the current + settings to be output. + + +Wed Jun 26 14:51:40 EDT 1991 + + eval.c Added range checks on assignment. + m2-exp.y Added the grammar for sets to the language. Currently, + these do not do anything except print an error message. + +Wed Jun 26 17:01:04 EDT 1991 + + m2-exp.y Added the ability for parse_number() to parse negative + numbers. A global flag is set upon encountering a unary + minus. This was done to make, for example, 1 parse as a + CARDINAL, and not as an integer, per Wirth's examples in + Programming in Modula-2 ed.4. + valprint.c Added support for "set radix 2" by then setting + output_format to 't'. + eval.c Implemented range checking on subrange types. Added calls + to range_check_range_p for BINOP_ASSIGN and BINOP_VAL. + Implemented MIN and MAX for ennumerated types. The + minimum value of an ennumerated type is defined by Wirth + as the first identifier, and the maximum as the last. + m2-exp.y Made octal numbers ending with "B" be characters and those + ending with "C" be numbers, per Wirth's book. (p. 34) + +Thu Jun 27 14:11:52 EDT 1991 + + stack.c select_frame() now only sets working_lang, it does not + notify the user. If working_mode is language_manual, then + a warning is issued once. + main.c At the end of each call to execute_command(), working_lang + is checked against the local static (enum language) + current. If they differ and working_mode is + language_auto, the new settings of language, type and + range checking are printed out. + stack.c Modified frame_info() to include the language of the + current frame in the output of "info frame". + language.[ch] Added the function language_str() which returns the name + of the current language. + +Fri Jun 28 15:33:14 EDT 1991 + + m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to + the language. INCL and DECL currently cause an error, + since sets are not implemented yet. INC and DEC are + implemented as PREINCREMENT/PREDECREMENT with one + argument, and as ASSIGN_MODIFY with two arguments. + eval.c Added type checking to the above cases. + value.h Added not_lval_constant to the lval_type ennumerated type. + not_lval_constant means that the value is a constant + value; that is 3 or 'a' or TRUE, not as in a constant + identifier. This is used to help coerce numbers such as 3 + to either signed or unsigned numbers. + valops.c Added the function value_coerce_constants() which coerces + constant integers as following: if one is a constant and + the other is not, the constant's type is set to the type + of the other argument. If both are constants and one is + signed, the other is converted to a signed constant. + +Sat Jun 29 17:26:29 EDT 1991 + + valarith.c Added a better range checker. It now checks range + (successfully) on integral operations [+-] (signed and + unsigned) for any C sized type. Still does not work well + for multiplication.) + int_in_size() returns an integer that is coerced to fit into + specified number of bytes. + +Mon Jul 1 13:04:14 EDT 1991 + + language.[ch] Added the function binop_result_type(), which returns the + builtin (struct type *) type that would be the result of a + binop on the two values V1 and V2. + +Wed Jul 3 19:22:53 EDT 1991 + + source.c Extended source_info() to include the source language in + the output from "info source". + +Fri Jul 5 13:48:52 EDT 1991 + + utils.c Moved the support functions for the GDB set/show commands + dealing with language into language.c. + language.c Added the function language_info(), which displays info + about the current working language, type and range check + settings. Called via the GDB command "info language". + Added an initialization routine _initialize_language(), + that sets defaults for the language, type and range + variables and sets up the new GDB commands. + main.c Language setup moved to language.c. + depend Rebuilt. + +Mon Jul 8 10:10:22 EDT 1991 + + valarith.c Debugged the range checker for arithmetic. Still does not + work for multiplication very well. + +Mon Jul 8 12:40:37 EDT 1991 + + language.[ch] Added the function value_true() which returns non-zero if + its argument represents a boolean true value. + breakpoint.c Changed breakpoint_cond_eval() to call value_true() to + check the truth of an expression. + +Thu Jul 11 12:51:34 EDT 1991 + + language.[ch] Added the predicate structured_type(), which returns + non-zero if the argument is a structured type. + Added the predicate pointer_type(), which returns non-zero + if the argument is a pointer type. + eval.c Added the ability to do addition and substraction on + pointers and integers. This case simply bypasses the + type checker. + +Thu Jul 11 14:41:42 EDT 1991 + + include/stab.def + Added the symbol N_DEFD (0x4a) which is a definition + module dependency that is used by the GNU Modula-2 + compiler and the linker. It is not important to GDB, + except that [dbx|coff|mips]read.c should ignore these + symbols. + +Fri Jul 12 16:07:00 EDT 1991 + + valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) > + 0 in val_print(). Also added statements to the else part + to coerce type (argument to val_print) to a pointer type + if it is an "array of unspecified length". + valops.c Added the function value_m2_string(), which returns a + (value) value which is a constant string, whose type is + (ARRAY [0..n] OF CHAR). The length field of the type + structure is set to zero, so it will be interpreted as an + "array of unspecified length". + stack.c Moved the language/frame mismatch check to + main.c:execute_command(). + main.c The working language is recorded each time + execute_command() is executed. If working lang has + changed during its execution, then the new + language/type/range info is printed out for the user. If + the working language does not match the language of the + frame, a warning is issued. + +Sat Jul 13 16:16:39 EDT 1991 + + eval.c Moved all the type-checking stuff for operators to + language.[ch] language.c. This is so we can keep language-specific + stuff (like for what type operators are defined) in + language.c. + language.[ch] Added the function binop_type_check(), which checks to see + if its two (value) arguments are type-compatible with its + opcode argument. The opcode should represent an operation + involving an operator. Also added the macro function + unop_type_check, which calls binop_type_check with a + NULL second argument. + expprint.c Added Modula-2 operators to the op_print_tab, so info + expression.h break works correctly. Also added "op_string", which + returns the string corresponding to the (enum exp_opcode) + opcode that is its argument. + + +Sat Jul 13 18:26:18 EDT 1991 + + coffread.c Added code to record the type of function arguments with + each paricular function. Code is very similar to that + added to dbxread.c. + dbxread.c Moved add_param_to_type() to symtab.c + symtab.[ch] Added function add_param_to_type() from dbxread.c + + *** NOTE: The above additions have not been tested. + +Mon Jul 15 12:50:47 EDT 1991 + + langauge.[ch] Added the functions type_error and range_error, which work + like error() except if the type/range mode is set to + *_mode_warn, then they do not do a return_to_top_level(), + but merely print a warning. + Also changed [set|show]_[type|range]_command() to support + the new "warn" feature. + +Thu Jul 18 17:50:54 EDT 1991 + + mipsread.c Added code to record the type of function arguments with + each particular function. Code is very similar to that + added to dbxread.c. + + *** NOTE: The above additions have not been tested. + +Fri Jul 19 11:19:10 EDT 1991 + + defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and + UMIN_OF_SIZE, which when given a size of a numeric type, + return the maximum and minimum value it can hold. UMAX... + and UMIN... return the result for unsigned types. + symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on + struct types.

Pretty up alldeps.mak with comments. + (depend): Don't try to do "gcc expread.y". + (expread.o): Update dependencies by hand. + +Mon Jul 29 15:21:09 1991 Roland H.

Pesch (pesch at cygint.cygnus.com) + + * doc/gdb.texinfo: + (1) Applied some fixes due to comments from Larry Breed (easier ones + through chapsec 5.2) + (2) Eliminated use of @footnote---had my doubts about it anyways, and + it's broken in latest texinfo + (3) Introduced *some* use of [] for optional arguments, where + explanation is not simpler by listing cmd w arg and cmd w/out arg + separately. Still not using @deffn. + (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a + couple of headings are too long. Need patches to texinfo or revision + to GPL-2. + + * Partial update to README (which still needs work for this + release!): (1) use of configure corrected for new script, + (2) "make gdb.dvi" and "make gdb.info" mentioned. + +Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com) + + * symtab.c (lookup_symbol): Don't complain right off about + no debug symbols; use the misc function vector first. + (list_symbols): Use misc function vector to find symbols + that don't have debug info, and print them. + (find_pc_symtab): Temporarily avoid fatal() when psymtab + PC range doesn't match symtab PC range, as it does on the + MIPS because our symtab reading isn't perfect. + + * dbxread.c (dbx_symfile_read): Make warning about + "no debug symbols" slightly nicer. + + * source.c (select_source_symtab): If "main" symbol exists, + but decode_line_spec can't find line info, don't just return + a zero; try other source symtabs or give an error. + + * mipsread.c (parse_partial_symbols): Sort the psymtabs by + their low addresses first, then rip through fixing high addrs. + + * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd, + <runene@ifi.uio.no>. + (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef. + +Tue Jul 23 18:52:43 1991 Roland H.

Clean up + bogus "off == 0" handling with a complaint.

Complain about unknown + type qualifiers. + (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *). + (psymtab_to_symtab_1): Print names of subsidiary files that + are being read in. FIXME, we read far too many files. This code + is not the problem, the problem is in parse_fdr where the psymtabs + are set up. + (cross_ref): Result should indicate that we used one aux entry + normally, or two if we encountered a "next" entry. This used + to leave the caller pointing at the wrong aux entry. + (add_symbol): If overflowed cur_block, reallocate it larger, + chase all pointers to it, and complain(), rather than clobber memory. + (shrink_block): Use xrealloc rather than xmalloc-and-copy. + (new_field): Only allocate one field initially, not two. + Pull ++ out of macro argument.

Elim LOC_EXTERNAL. + (print_frame_args): Keep track of param stack offsets before + re-looking up to find the local register param is kept in. + + * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>. + Further integration of mipsread into gdb. Eliminate unused + routines, duplicate declarations. Handle static symbols in + psymtabs as well as external symbols. When reading symtabs, + insert symbols into the correct block (global, static, or a local + block). + (read_mips_symtab, parse_partial_symbols): Don't pass useless + "incremental" arg. + (mipscoff_symfile_read): Don't call select_source_symtab. + (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate, + rather than SYMBOL_VALUE. + (parse_external): Comment clobbering of top_stack. + (parse_partial_symbols): Update comments. Allocate and parse + static symbols as well as external symbols. FIXME, enum values + are not handled in this pass, but should be. Inline new_psymbol. + Use SYMBOL_VALUE_ADDRESS. + (psymtab_to_symtab_1): Read symbols into global static block + by default (until enter some function's local block context). + (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK. + (destroy_all_symtabs, new_psymbol): Eliminate, unused. + + * source.c (select_source_symtab): Select a source symtab + from either the symtabs or, failing that, the psymtabs. + (list_command): Update error message. + (forward_search_command, reverse_search_command): Use getc, not + fgetc, for speed. FIXME, add comment about buffers that die if + overrun by long line. + + * values.c (unpack_field_as_long, modify_field): Avoid shifting + by an entire word, which is not portable, if we have a 32-bit + field. (Code in dbxread.c already turns such bitfields, if + aligned, into ordinary ints, but fixing this will help for other + symbol formats and for future changes.) + * core.c (core_open): Handle ANSI const brain death. + * utils.c (vprintf): Fix varargs typo. + +Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com) + + * findvar.c (find_var_value): Handle &function better. + * TODO: Document work needed on &fn and &array. + * printcmd.c (print_address_symbolic): New arg is the prefix + to print if a name is printed. + (print_address_demangle): Honor "set print address" now. + Use new arg above to improve spacing of output. + * valprint.c (val_print): When printing function pointers, + print symbolic form too. + * breakpoint.c (breakpoint_1): Use new print_address_symbolic. + +Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com) + + * core.c (memory_error): Reword error msg to mislead less. + + * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name. + + * mipsread.c (read_mips_symtab, read_the_mips_symtab, + parse_partial_symbols): Use newer BFD internals (external_filehdr + and external_aouthdr), byte-swap the fields that we care about + before using them, and make the file header data local to + read_the_mips_symtab rather than global. + +Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com) + + * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix + from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991. + + * main.c (command_line_input): Flush stdout and stderr + before every call to readline.

Good, since that hack confused code in symfile.c! + + (reorder_symtabs, destroy_all_symtabs): Removed static + all_symtabs, which was used to qsort symtabs in reorder_symtabs. + Instead, the latter now uses a temporary array (stack-allocated + from an obstack, and then freed). + + (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they + haven't been set in the outermost stBlock of a procedure. This was + a problem with f77 binaries on Ultrix 4.?. + + (new_symtab, new_symbol, new_type): Continue changing code to use + obstacks more and otherwise conform to dbxread internal style. + Made the free_code of symtabs be free_linetable (as in dbxread) + instead of free_contents. This implies memory leaks when reading + a new symbol table, until the conversion is finished. Did change + (struct symbol) and (struct type) to be allocated on the + symbol_obstack. Blocks and blockvectors are among the things + still "leaking." + + * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been + tested much, but it solved one problem (reported by Meissner), and + cleans up some other things. The problem happened when an + included file contains actual code (functions) and not just + definitions. The mips coff is a little inconvenient there, since + it may cause a procedure to be mapped to the wrong psymtab. + + * mips-tdep.c (heuristic_proc_desc): Minor cleanup. + * mips-xdep.c (fetch_core_registers): Minor cleanup.

This really + needs to be generalized to a timestamp per file. + + * core.c (cleanup_core): Avoid coredump if no core file. + + * config.gdb: Accept -host or -target in place of +host or + +target. + + * coffread.c (find_linenos): Avoid desupported BFD interface + to line numbers. We still read them manually rather than using + BFD's "generic" features. + + * gdbrc.tex, threecol.tex: Add GDB reference card and its + formatting code. + Makefile.dist: Add refcard to OTHERS list for creating tar files. + + * Makefile.dist: Eliminate use of $< in explicit targets. + + * readline/Makefile: Use $< rather than $*.c, which does not + include the VPATH in GNU Make. + + * tconfig/i960-bout, tconfig/i960-coff: These are identical + copies of tconfig/i960, added for global configuration + compatability. All i960 versions can read both coff and b.out. + + * tm-88k.h: Fix multiline macro that lacked \'s. Remove + COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled + automaticaly. + + * TODO: Think of more things to do. + +Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com) + + tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config + of sdb versus dbx debug symbols.

Add symfile.c. + Link in both dbxread and coffread. Fix up "make depend" to + rewack the locations of include, bfd, and getopt in its output. + + * README: Document moving include files, improve some of + the other doc. + + * coffread.c: Move common code out to symfile.c. Change + symbol_file_command style interface to use new *_symfile_init + and *_symfile_read interface under BFD. Use BFD internal + info to locate line table, symbols, etc. + + * core.c (core_fetch_registers): Rename to get_core_registers + to avoid confusion with fetch_core_registers. + (register_addr): Move to coredep.c, which is already machine + dependent. This leaves core.c pretty clean of dependencies. + + * coredep.c (register_addr): Accept this routine from core.c. + + * dbxread.c: Move common code (with coffread.c, etc) into new + symfile.c. Each psymtab now contains a pointer to the + format-dependent function that knows how to read it in. Make + some things static. + (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2. + (process_one_symbol): Add code to complain about a "compiler bug + we muzzle here", if we actually see it. + + * eval.c (evaluate_subexp): Insert missing "break" statements + in code that determines whether a variable is an lvalue in + memory, register, or whatever. I detected this via a compiler + bug in which it *almost* mashed out the whole switch statement. + + * gdb-int.texinfo: Add minor sections on configuring gdb for + release, and about the README file. + + * infcmd.c (registers_info): Fix formatting somewhat. Still + not as pretty as before, but it handles byte swapping. + + * remote-nindy.c: If data cache routines are interrupted while + waiting for the remote end, be sure that any uninitialized cache + blocks are on the free list, not on the valid list! + + * symfile.h: Flesh out this header file with all the various + routines and variables that have been merged in from dbxread.c + coffread.c, and symtab.c to symfile.c. + + * symfile.c: New file, containing code common to dbxread.c, + coffread.c, and some code from symtab.c. All generic code for + reading symbol files should be in here now. + (unrecord_misc_function): Remove unused function. + + * symtab.h: Remove file-reading things to symfile.h. + + * symtab.c: Remove file-reading things to symfile.c. + + * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL + to decode i960 fault types. + + * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c, + target.c: Change type of the "resume" function from int to void, + since its result was never used. + +Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint) + + * main.c: Replace "stupid" with "caution"; you now "set caution + on or off". + + * printcmd.c (print_scalar_formatted): Fix typo in 'g' format + + * infcmd.c (do_registers_info): Call val_print to deal with the + byte order of the registers being printed. FIXME, this makes + the formatting of the output uglier. + + * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is + defined, call it for signals the debugger doesn't itself use. + The i960 uses this for more detailed fault information. + + * remote.c (remote_open): If arg is null, print help rather than + dumping core. + + * sparc-xdep.c (register_valid): Avoid declaring size, since + various modules will think of various sizes depending on the + architecture of their tm-file. FIXME, we need protection against + actually entering one of those modules, which would clobber + storage if not for the target architecture compiled into gdb. + + * stack.c (up_command, down_command): Always print the frame + you arrive at. + (up_silently_command, down_silently_command): New commands + for use in scripts. + + * i960-pinsn.c (reg), i960-tdep.c: Lint. + + * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes + more parameters than it used to. + + * findvar.c (registers): Increase slop to 256 bytes, which should + protect us against even most RISC machines with large register + sets. + (locate_var_value): Move declaration inside related ifdef. + + * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP + throughout, to avoid throwing away buffered input from the board. + (nindy_wait): Supply_register takes addr_of_value, not value. + (i960_print_fault): Renamed from i80960_fault. + (nindy_fetch_registers): Avoid have_regs stuff, just get them. + (nindy_store_registers): Avoid regs_changed stuff, just stuff + them. + (nindy_create_inferior): Don't bother to write PC_REGNUM since + we can set the PC in the call to proceed(). Unpush nindy_ops + before pushing it on top, to avoid message to user. Eliminate + commentary from Unix machines that just misleads here. + (reset_command): Fix error message to suggest target command. + +Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint) + + Release 3.92.5 as frozen. + + Stabilize the merged release...with help from lint, Saber C, + gcc -W, etc. + + Everywhere: Add include files needed to declare return types + of functions called. + + * gdb.texinfo: Roland Pesch is documenting gdb, glory be! + + * breakpoint.h: Add undeclared breakpoint functions, and some + functions for display handling since I couldn't think of a better + .h to put them in. + + * breakpoint.c (insert_breakpoints): Make code for disabling + shared library bkpts more likely to work. It's used when we + rerun a program and stop before the shared library has been + mapped in. + (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int, + cast from pointer, so it squeezes through catch_errors. + (bpstat_stop_status): Fix logic broken some time ago. We now + always create a bpstat if the stop address matches a breakpoint, + even if we don't stop there -- just like the old code used to do + before I got my fingers into it (sigh). + (breakpoint_1): Print "ignore count" after "stop only if" + condition, since that's how it actually works. + (mention): Handle watchpoints as well as breakpoints. + (watch_command): use set_raw_breakpoint and mention to do most + of the work (and initialize all the fields!). Only pass one + arg to parse_c_expression, since that's all it takes. + + * command.c (not_just_help_class_command): Rename arg to args + since we ignore "unused argument" warnings on vars named "args". + inflow.c (child_terminal_info): ditto. + infptrace.c (kill_inferior): ditto + main.c (catch_errors, version_info, quit_command, pwd_command, + source_command, dump_me_command, editing_info, + set_history_size_command, set_history, show_history, + set_verbose): ditto + stack.c (locals_info): ditto + target.c (target_files_info): ditto + valprint.c (set_input_radix, set_output_radix): ditto + + * core.c: Remove old variables for handling core and exec file + sections (data_start, data_end, stack_start, stack_end, + reg_stack_start, reg_stack_end, reg_stack_offset, text_start, + text_end, exec_data_start, exec_data_end, text_offset, + exec_data_offset, data_offset, stack_offset). They're + superseded the more general build_section_table and + xfer_memory. + (get_exec_file): Mention the `file' command. + (read_memory_check): Rename to memory_error, and only call it + in the case of an actual error. + (read_memory, write_memory): call memory_error. + (core_fetch_registers): Register section name is ".reg". + + coredep.c: Remove a bunch of crud now that all this file does + is pull the registers out of a core file. + (fetch_core_registers): Rewrite to actually work, I hope. + + dbxread.c: Use a.out.gnu.h, not system a.out, now. + Replace index() with strchr(). Remove all the pre-BFD macro + definitions for accessing the symbol file. + (struct dbx_symfile_info): Encapsulate the information that + dbx_symfile_init needs to pass to dbx_symfile_read in this + struct. + + (dbx_new_init, dbx_symfile_init, dbx_symfile_read, + dbx_symfile_discard): Rearrange symbol file reading to divide + the format-specific part from the format-independent part, + leaving the format-independent part such as file name expansion + and opening in symtab.c. This replaces + partial_symbol_file_open and partial_symbol_file_read. + Symbol_file_read, add_file, add_file_target_command, + add_file_addr_command move to symtab.c. Pass an explicit + "mainline" flag for when reading the main symbol table, rather + than relying on the offset address to be zero or nonzero. + + (dbx_symfile_read): Don't allow void *'s to be printed as + typedefs. + (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols. + (ADD_PSYMBOL_TO_LIST): Make the "function call rather than + macro" debug version really work. + (read_dbx_symtab): Remove unref'd parameter inclink. + Avoid swapping N_SLINE symbols, for speed. + Merge N_TEXT!N_EXT case with the other external symbol + definitions' case. Add comments. + (start_psymtab): Allocate the symfile name in the psymtab on + the psymbol_obstack, rather than using the caller's storage. + (end_psymtab): Only allocate a dependencies list if there are + more than zero. + (psymtab_to_symtab_2): Use BFD when reopening file to read + its symbols for real. + (read_struct_type): Add FIXME comments where it needs work + for C++ bogosity. + (read_huge_number): Add FIXME about overflows. + (read_range_type): Add FIXME about comparing a long to 1<<32. + + * coffread.c: Minor changes to move things closer to the new + regime with symtab.c and dbxread.c Major work is still needed + here. + + * exec.c (exec_file_command): Remove old variables (see core.c + above). + (xfer_memory): If memory transfer is right at the end of a + section, don't lose. + + * findvar.c (get_saved_register): If value is in a real + register, LVAL is lval_register, not lval_memory. + + frame.h: Declare print_sel_frame and record_selected_frame. + + gdb-int.texinfo: New file, for GDB internals documentation. + Very simple, unformatted doc of cleanups is there for now. + + gdbcore.h: Remove obsolete variables that described a.out + section addresses and offsets. (See core.c above.) + Declare fetch_core_registers and registers_fetched. + + getopt.c: Declare char *alloca(); even on SPARC. + + infcmd.c (run_command): Call target_kill rather than + kill_inferior. + (step_command, next_command, stepi_command, nexti_command): + Declare from_tty parameter even though we don't use it. + (run_stack_dummy): argument BUFFER is a char array, not + a pointer to REGISTER_TYPE. + (finish_command): using_struct_return needed a value *, + not a struct symbol *. + + * infptrace.c (child_xfer_memory): To avoid dependency on + where sections are in memory, try PT_WRITE_D and if that fails, + try PT_WRITE_I. Most Unixes don't care which you use. + + * infrun.c (step_resume_break_shadow): Change to array to + match other breakpoint shadow storage. + (clear_proceed_status): Pass address of bpstat to + bpstat_clear, not the bpstat itself. + (child_create_inferior): FIXME comment about if the child + exits. + (start_inferior): Remove old function. + (child_open): Use target_kill rather than kill_inferior. + (wait_for_inferior): Ditto. + (insert_step_breakpoint, remote_step_breakpoint): Use + new step_resume_break_shadow. + + * inftarg.c (child_wait): If all child processes die, + pretend that the one being waited for exited with signal 42. + + * main.c (command_line_input): When scanning for comments, + don't coredump on unclosed quotes. + (quit_command): Use target_kill rther than kill_inferior. + (_initialize_main): Rename class_user from "user" to + "user-defined". + + * printcmd.c (print_command_1): Initialize "fmt" if no format + is specified by the user. + (print_frame_args): Only add to args_printed if we are + actually fetching args from the stack (avoiding undefined + arg_size). + (_initialize_printcmd): Remove bogus \{ from string. + + * remote-eb.c (eb_open): Avoid coredump on no argument. + + * remote-nindy.c: Bring out of Intel environment into new + target environment.

The rest is Bothner speaking: + + The next message is a merger of Alessando Forin's mips port with + mine. I've tried to use my good if biased judgment to get + the best of both. It *does* need testing. + + Some of the changes are general, *not* mips-specific. + + param.h: + Didn't believe in little-endian bit order. + There are still inconsistencies about whether flags + like BITS_BIG_ENDIAN are integer (#if ...) or + boolean (#ifdef ...). I tried to paper over them. + + dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h: + Moved some misc_function code that was common to + {dbx,coff,mips}read.c to symtab.c. + In the process, I think I cleaned things up a bit. + At the same time, moved obsavestring and obconcat to symtab.c. + + dbxread.c: + Removed obsolete condense_addl_misc_bunches (use + condense_misc_bunches(1) instead). + + exec.c: + Needed to include <sys/dir>, at least on DECstations. + + valops.c, mips-tdep.c, tm-mips.h: + Added PUSH_ARGUMENTS macro to support funny argument-pushing + conventions (when STACK_ALIGN is insufficient). + Needed on mips, where doubles need 8-byte alignment, + but ints only need 4. + + mips-opcode.h: + Removed cruft that was not being used. + Merged in many fixes (most from Frank Yellin, fy@lucid.com). + + mips-pinsn.c: + Print $ before register-names (I think that makes things a little + more consistent). + Never print two instructions, even if one delays. + Removed hex-disassemble set_cmd. (This is not mips-specific, + so I think the argument is whether it is generally worthwhile or not. + I'm inclined to think not, given how easy it is to + convert between radixes in gdb.) + + mipsread.c: + This is basically Alessando's code. + It doesn't use obstacks; I changed it to use obstacks + in a few minor places where using malloc causes a + memory leak. (Probably, more places could/should be changed.) + I added record_misc_function where it was missing. + In symbol_file_command and add_file_command, I tried + to make the code consistent with more recent versions. + Minor sylistic changes in parse_procedure. + Make a .gdbinfo. psuedo-symbol point back to the real + procedure symbol (using the isym field). + + mips-tdep.c: + This is basically from my port, but with a lot of details + and a number of routines merged in from Alessando's version. + I basically used my code "raw" backtrace (use heuristics + from the actual code, rather than symbol table info) - though + the idea is Alessandro's. I feel my code is a little cleaner + here, particularly in being a little more flexible, such as being + able to handle gcc-produced code (which it now can). + It also doesn't do frame caching (which is not useful + more recent gdb versions). + I also used my code for push_/pop_dummy, more or less. + I tried to incorporate AF's code for testing sigtramp + while backtracing; I probably got it wrong. + Added mips_print_register, which tries to scrunch as much + information as possible on a screen... + Removed the skip-prologue set_cmd. As with hex-disassemble (see + under mips-pinsn.c), I don't see anything mips-specific here, + and I don't see it being all that useful anyway. + + tm-mips.h: + Added a $fp psuedo-reg distinct from $fp (nice for gcc). + Use more register names (rather than hard-cases numbers). + +Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint) + + * Hack up 3.90.11 changes: + + * Makefile.dist (depend): parameterize $(GCC). + Add solib.c and solib.o. + (readline): Fix vpath for both absolute or relative SRCDIR. + + * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs. + Also, let the part I didn't understand at least compile so + I can test the rest. FIXME. + + * dbxread.c: Fix thinko using strcmp. + (init_psymbol_list): declare static. + (partial_symbol_file_open): Comment cleanups better, avoid + cleaning up the string table since the caller will do that. + Move the stat for mod time into symbol_file_command, temporarily. + (There should be a mod time for each symbol file, eventually, + to control its rereading. FIXME.) + + * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for + SunOS, which gives error for shared libs otherwise. (From + Schaefer, probably FIXME needs work for portability.) + + * solib.c: Move #include "param.h" to work. + Lowercase all the Uppercase Letters In the Messages. + (find_solib): Clean up inferior_so_name for debug printouts. + Allow no argument, to mean all shared libraries. + + * symmisc.c: include param.h to get CLEAR_SOLIB. + +Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint) + + * Merge in Kingdon's changes from FSF: the diffs from 3.90.9 + to 3.90.11.

Here are my suggestions. + + These patches all attempt to handle TYPE_CODE_REF (as in C++) better. + + findvar.c: + Do automatic de-reference when taking the address of a reference. + printcmd.c: + Don't deref_ref when printing parameter lists. + valops.c: + More attempts at treating refernences properly. + valprint.c: + In val_print, if deref_ref==0, don't print dangling " = ". + value.h: + Add COERCE_REF macro, which de-references an REF. + + * Merge changes from Per Bothner: + +* Fixed (Sony news)-specific configuration problems. +* Fixed other problems with using vanilla pcc and libc (enum problems; +assumption that vsprintf exists). +* Some major speed-ups (finc_pc_partial_function now caches a match; +parsing avoids duplicate symbol_lookup calls). +* Changed handling of baseclasses (no longer use baseclasses field +of struct type, use the first n_baseclasses fields instead). +* Various minor changes/fixes, most C++-related. + +blockframe.c: +Cache the most previous match from find_pc_partial_function. +(Save both low and high ends of matching function's pc range.) +This speeds up the loop of infrun.c:wait_for_inferior quite +a bit, and makes step/next commands much zippier. +command.c: +Added an enum->int cast (otherwise, some compilers barf). +dbxread.c: +No longer set baseclass offset to 0, since multiple +inheritance now mostly works. +Added a number of casts, to shut up compiler warnings +(after stabs where made enums, not ints). +When discarding a symbol table (in symbol_file_command), +must clear the cache introduced in blockframe.c. +Don't convert $vtbl_ptr_type to vtbl any more. +Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h). +Mask off sign bit emitted by g++ for virtual table offset. +Set voffset to -1 (not 1) for static member functions. +expread.y: +Changed parsing/lexing of names to avoid doing symbol lookup twice +(once when lexing to determine symbol class, once for real). +Now only call symbol_lookup once. Fields of 'this' win especially big. +printcmd.c: +Subpress printing addr twice in the case of 'x/s addr'. +symtab.c: +lookup_basetype_type is no longer used. +Add find_methods as recursive helper function to decode_line_1. +This allows multiple inheritance to work. +Also, once one or more matches has been found, do not look in +base-classes. (Baseclass methods would be overridden, anyway.) +symtab.h: +Removed baseclasses array in struct type. +Instead of using baseclasses[i], use fields[i-1]. +Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual. +Changed sign convention of voffset (previous was inconsistent). +tm-news.h: +Some macros (CALL_DUMMY and relatives) were missing. Put them back. +utils.c: +Used to assume existence of vsprintf. Re-written to not need it +if HAVE_VPRINTF is undefined. +valops.c: +typecmp was too pessimistic. Made it less so. +valprint.c: +Don't print space after address. +If vtable points to a misc symbol (with 0 offset), print it, +since that indicates the actual class of the object. +Changed ype_print_derivation_info to use new inheritance +scheme (without baseclasses vector). +values.c: +In value_primitive_field, fixed some bugs left over from previous set of fixes. +Also, changes needed because TYPE_BASECLASSES were removed. +xm-news.h: +REGISTER_U_ADDR didn't work for PC. Rewrote to use an array. + +Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint) + + * source.c: + If there is no path set, and the symbols don't indicate what directory + a file was compiled in, look in the current directory. But either + a path or a known compilation directory will prevent this. + + * dbxread.c: + Three independent bug fixes: + * Remove the #if 0 block that breaks some stuff. + * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C; + adapt gdb to either SunOS 4.0.* or 4.1. + * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think. + + * symtab.c: + Instantiate the class T when looking for methods in it. (Tiemann@sun) + + * valprint.c: + (type_print) Demangle the name being printed. + (type_print_base) Handle botched demangling without coredump (tiemann). + + * values.c: + (check_stub_method): Document routine. + (tiemann) fix bug for no-arg functions + Avoid clobbering beyond end of malloc'd storage. + Terminate the argument list properly. + +Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu) + + * Changes merged by John Gilmore: + +breakpoint.c: + In breakpoint_1, use new print_address_symbolic instead + of find_pc_partial_function. (This forces use of assembler-level + addresses, and avoids misleading non-mangled source-level names.) +cplus-dem.c: + Generalize ansi argument such that -1 means skip arglist totally. + Removed global variable print_ansi_qualifiers (which made + code non-reentrant), in favor of extra explicit arguments + to internal routines. +printcmd.c: + Add new helper function print_address_symbolic. + Use find_pc_misc_function instead of find_pc_partial_function + (since we want assembler-level symbols here). +stack.c: + Print unknown function as just "f (...)", not "f (...) (...)". + Use new fputs_demangled explicitly. +symtab.c: + Fixed a typing violation (problem: value.h cannot be imported + without renaming many variable in this file). + lookup_symbol: If no matching misc_func, look for a C++-mangled name. + decode_line_1: Moved forward some never-reached code. + Made decode_line_2 skip function prologues correctly. +utils.c: + fputs_filtered should not demangle by default. + Add new fputs_demangled to demangle on demand.. +valops.c: + Change value_struct_elt to use value_primitive_field (using recursive + utility function search_struct_field). This allows foo.bar to work + for multiple inheritance (so far only for data fields). + Change check_field in the same way (recursive helper function + to support multiple inheritance). + (Note: there are more of these problems that I haven't fixed. + Any code that says TYPE_BASECLASS (t, 1) is probably wrong.) + value_of_this: 'this' symbol name is now just "this", note "$this". +valprint.c: + Don't print static members. + Avoid printing "members of <type>" if there are none. + Simplified type_print_derivation_info by merging duplicate code. + Remove useless blank lines in type_print_base (ptype command). +value.h: + Added declaration of new routine value_primitive_field. +values.c: + Added value_primitive_field which is generalized version of + value_field that can handle multiple inheritance (non-zero offsets etc). + Re-implemented value_field to call value_primitive_field. + +Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint) + + * infcmd.c -- insert else to avoid 'delete env' coredump when you + delete the whole environment.
