+
+	* unroll.c (find_splittable_givs): When completely unrolling loop,
+	use biv initial value stored in splittable_regs instead of
+	bl->initial_value, since the later may not be safe.
+
+	* sched.c (schedule_block):  When calculating whether a register
+	crosses a call, must do this after registers are killed and before
+	new registers are made live.
+
+	* x-rs6000: Define INSTALL as /usr/ucb/install -c.  /etc/install
+	(the SYS V version) does not handle -c option as Makefile.in
+	intends it.

+
+	* mips-tfile (parse_stabs_common): Don't relocate N_LBRAC and

+
+	* cp-decl.c (grokdeclarator): Don't set TREE_PRIVATE here.
+	TREE_PRIVATE is only for visibility.

+
+Mon Jan 13 07:31:38 1992  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* rs6000.c (output_ascii): The AIX assembler silently truncates
+	strings longer than 666 characters, so break them up well before that.

+Mon Jan 13 00:26:47 1992  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* c-decl.c (pushdecl): Warn about shadowing at top level any symbol
+	that was declared among the function parms.  But don't warn for

+	* fixincludes: Insert #undef NULL before #define NULL.
+
+	* gvarargs.h (va_list): Check some macros to avoid redefinition.

+Sat Jan 11 22:04:34 1992  Michael Meissner  (meissner at osf.org)

+	conversions regardless of whether we have CONTRAVARIANCE_HARSHNESS
+	or not.  Also, `#if 0' some dead code.
+
+	* cp-method.c (report_type_mismatch): Fix bugs in formatting error
+	messages.
+

+	standard call insns.
+	(PIC call, call_value): New define_insns which output PIC calls.

+
+	* i386.md (mulhi3,mulsi3): If a multiply by constant 128, use the

+
+	* dbxout.c (dbxout_type): Tiemann's DECL_IGNORED_P optimization (Nov
+	20) was a little too drastic: If it succeded, no type info was
+	emitted at all, which made for syntactically invalid stabs.
+	Instead, just set 'full=0',
+	* dbxout.c (dbxout_symbol): Re-write code for TYPE_DECL to be a
+	little cleaner.  It *seems* to work ...
+

+
+	* expr.c (convert_move): Add truncates from DImode to smaller modes.

+	register for those loads that need it.  When loading a pic label,
+	set %o7 instead of clobbering it so its value can be used later.
+	(compute_frame_size): Leaf functions need to allocate space for
+	register window in frame if size greater than 0.
+	(print_operand): Delete obsolete %^ which added %o7 to addresses.
+	All uses of %o7 are now explicit.

+	* sparc.md: Fix all callers of legitimize_pic_address and
+	emit_move_sequence.
+	(reload_insi): New pattern.  Used to force reload to allocate a
+	scratch register for those pic address loads that need one.
+	(reload_insi+2): When loading pic label, set %o7 instead of
+	clobbering it.
+	(movdf, movsf): Reject matches that would require reloading via
+	use of a condition.
+	(tablejump): Now a define_expand, so can generate different

+
+	* genrecog.c: Major rework.
+	We now check to see if pairs of comparison nodes can have anything
+	that they both match.  If not, they can be reordered.  An efficient
+	ordering is established that groups all nodes with identical rtl
+	codes inside groups with identical modes.  This allows us to generate
+	a comparison tree that is a list of nested switch statements.
+	Also, genrecog.c is now indented properly so that debugging is eased.
+	(add_to_sequence): Enforce mode on the first arg of COMPARE, comparison
+	operation, SIGN_EXTEND, and ZERO_EXTEND.

+	All callers changed.

+
+	* cp-spew.c (do_aggr): New function. Looks ahead from AGGR to see if

+
+	* m68k.c (output_function_prologue, output_function_epilogue):
+	When saving/restoring only 2 registers, do so with two "movel"

+	faster code for the 68020 and later machines.
+
+Wed Dec 11 06:45:08 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)

+	moved to gnulib2.c.
+
+	* Makefile.in (collect2, collect2.o): Change to use the default

+	otherwise, collect2 will create a circular dependency.  Also, pass

+
+	* collect-osf.c (write_s_file): Change to the new way of doing
+	constructors and destructors of having an end marker instead of a
+	count.

+	destructors of having an end marker instead of a count.  Cast all
+	alloca calls to be the appropriate pointer type.  Put both
+	constructors and destructors into the data section, because the MIPS
+	tools do not like non-instructions in the .text section.
+
+	* decrose.h (HAVE_ATEXIT): Define, OSF/1 has atexit.

+	needed, since constructor/destructor support moved into gnulib2.c.
+
+	* t-i386rose (LIB2FUNCS_EXTRA): Remove, osf-main.c is no longer

+
+	* t-decstatn (CCLIBFLAGS, GNULIB2_CFLAGS): Define so that gnulib1
+	and gnulib2 are both compiled with -G 0, in case the users compiles
+	and links this way.  It also fixes a bug where the constructors and
+	destructors that collect2 produces are in the big data section, but
+	gnulib2 thinks they are in the small data section, because it only
+	sees a pointer.
+	(ld): Add -f to remove old ld link to collect2, if it exists.
+
+	* t-mips (CCLIBFLAGS, GNULIB2_CFLAGS): Define so that gnulib1
+	and gnulib2 are both compiled with -G 0, in case the users compiles
+	and links this way.  It also fixes a bug where the constructors and
+	destructors that collect2 produces are in the big data section, but
+	gnulib2 thinks they are in the small data section, because it only
+	sees a pointer.
+	(ld): Add rule to link collect2 to ld.
+	(EXTRA_PASSES): Build collect2 (aka ld).
+
+	* xm-mips.h (alloca): If not GNU C, declare alloca to be char *.
+
+	* mips-tfile.c (add_aux_sym_tir): Move code to record bitfield size,
+	so that it agrees with MIPS ECOFF practice, rather than the
+	documentation, which affects enum bitfields.  Changes from Per
+	Bothner.
+

+	pointer-to-method as well.  Don't build an OFFSET_REF for any
+	"function" that already has pointer type.  Only use

+	(mips_fill_delay_slot): Instead of taking the number of nops as a

+	instruction would modify the hi/lo registers.

+
+	* mips.md (various): Add 64 bit integer operations for addition,
+	subtraction, negation, and, inclusive or, exclusive or, one's

+	multiply, which the compiler then uses to construct 64 bit
+	multiplies.
+	(mulsi3): Break mul into it's two instructions, and schedule the
+	two nops needed for the mflo instruction.  Don't allow an integer

+	(movdf define_split): Add a define_split to separate the two parts
+	of DFmode register pairs when using GP registers.
+	(mov??_internal): Change condition to call memory_operand, instead
+	of just checking for MEM, which disallows (subreg (MEM)) during

+	define_expand for subsi3.

+	at the expense of potentially not moving the constant out of loops.
+	(various): Add = constraint to all clobbers.

+	unoptimized compiles call abort otherwise, when returning the result
+	of truncating a float as a function result.
+
+	* tm-mips.h (delay_type): New enum to express different types of
+	delay slots.
+	(mips_load_reg3, mips_load_reg4): Declarations for more registers
+	to check for needing nops.  Used by multiply/divide to schedule
+	the two nops needed after mfhi/mflo if the next instruction would
+	clobber the register.
+	(CONDITIONAL_REGISTER_USAGE): If -msoft-float, disable all FP
+	registers.
+	(MASK_DEBUG_G): Add comment saying -mdebugg turns of new DImode
+	patterns, in case the code is wrong.
+	(HARD_REGNO_NREGS): All FP registers use register pairs, so that
+	SF in a GP register takes only one register, and SI in a FP
+	register takes 2.
+	(HARD_REGNO_MODE_OK): Change macro to reference the array
+	mips_hard_regno_mode_ok, which is now built in override_options.
+	(CONST_OK_FOR_LETTER_P): 'N' is now for negative numbers, 'O' is
+	an exact power of 2, and 'P' is now for positive numbers.
+	(PREFERRED_RELOAD_CLASS): If -msoft-float, never prefer a FP
+	register.
+	(PREFERRED_RELOAD_CLASS_FM): Delete, since nobody uses it.
+	(FINAL_PRESCAN_INSN): Check for mips_load_reg3 and mips_load_reg4
+	being mentioned.  Also add a missing tab when more than one delay
+	slot.
+	(CONST_COSTS): Make all constant ints cost 0 to lower register
+	pressure according to Richard Kenner.
+	(RTX_COSTS): Adjust costs for DI, SF, and DF modes, and add ABS/FFS
+	costs as well.
+	(REGISTER_MOVE_COSTS): Bump costs for moving between register
+	classes, so that reload doesn't try to store int type values in the
+	floating point registers.

+	correct.
+	(lookup_tag): Bypass redefinition error message for UPT as well as
+	for TEMPLATE_DECL.
+	(start_decl): Add template decls only to top level.  Print message

+	the same, and it's cheaper this way.
+	(build_overload_name): Make template-related names unique, as well
+	as unlikely to be accepted by the assembler.
+
+	* cp-parse.y (yyprint): Handle PRE_PARSED_CLASS_DECL.
+	(template_def): In case handling destructors, pass new decl to

+
+	* cp-pt.c (overload_template_name): If not class-level, push

+
+	* out-sparc.c (output_cbranch): Always emit a nop before a FP branch
+	to avoid illegal assembly output.

+
+	* cp-typeck.c (c_expand_return): Be more careful about throwing
+	away only cleanup generated by 'build_functional_cast'.
+
+	* cp-init.c (build_new): Use TRUE_TYPE instead of TYPE more
+	consistently, in case TYPE is really an ARRAY_TYPE on its own.
+

+	this function. 
+	(dbxout_type_{method,method_1}): Move code from `dbxout_type' into
+	these new functions.
+	(dbxout_type): Now writes out info about basetypes.  Also, no longer
+	need to record info about types having ctors, dtors, or both.  GDB
+	now figures out what it needs to, when it needs to.
+	(dbxout_symbol): Implement special abbreviated form for C++ classes,
+	which place their names in both the struct and decl namespaces.
+	(dbxout_block): Write out special debugging stabs for exception
+	handler blocks.

+
+	* c-typeck.c (build_binary_op_nodefault): Delete ERROR_CODE
+	argument because it is always the same as CODE.  Add new argument

+	* c-common.c, c-convert.c, c-decl.c, c-tree.h, c-typeck.c: All
+	callers and other references to build_binary_op* fixed.
+	* c-typeck.c (new build_binary_op): Add warning message for

+	(main): No longer uses static sized array for ld arguments, so
+	that long command lines will work.  Vfork ld instead of running
+	via popen with nm.
+	(write_hooks): Use type names not variable names in sizeof calls.
+
+Fri Nov 15 15:01:41 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

+
+	* configure: Recognize only canonical names.  Added missing entries
+	for some configurations that obviously have not been tested in a
+	while.
+
+	* config.subr: Massive overhaul.  It claimed to canonicalize
+	the machine specification, but it never really did.  Now it
+	does.  In general, it is not necessary to specify the os for
+	popular machines that have a popular os, or given the os, it
+	can sometimes figure out the vendor.  Added in all the old
+	ways of specifying machines from configure.  Also added
+	support for all (before it was missing a few) of the tm-*.h
+	files.  It now supports the concept of guessing the vendor for
+	a given CPU type.  It now supports the concept of guessing the
+	os version given the vendor and/or the CPU type.  Changed the
+	default os for vax to ultrix, changed the default os for i386
+	to sco.
+
+	* collect-ld:  New file.  It is useful when compiling C++ programs
+	on machines that use collect.  This includes the decstation.

+	* tm-sparc.h (LEGITIMATE_CONSTANT_P): Accept anything except a
+	floating point constant.
+	Declare singlemove_string so it can be used in sparc.md.

+	one from the absolute value of something to PLUS, since we
+	subtract one using a PLUS operation.
+	(simplify_comparison, case MINUS): Handle GT case done by
+	emit_store_flag.
+	(simplify_comparison, cae IOR): Similarly, for IOR.
+
+	* tm-rs6000.h (BRANCH_COST): Define as 2.
+	* rs6000.md (scc): Allow some more cases.
+	(new scc patterns): Add numerous patterns to reflect superoptimizer
+	results for scc insns on RS/6000.

+
+	* mips-tfile.c (all): Change small allocation requests to use
+	separate allocation and free functions, instead of using the word8
+	union to hold each request.  In order to support this easily, a free

+	(main): If debugging, print a summary of the number of small
+	allocations, frees, and the number of pages used.
+	(add_procedure, copy_objects): Stuff the pointer to the end symbol
+	into the shash chain, and use it's value to generate the new value

+	we use.

+
+	* tm-mips.h (ASM_OUTPUT_REG_PUSH, ASM_OUTPUT_REG_POP): Correct so

+Fri Nov  8 12:05:39 1991  Per Bothner  (bothner at cygnus.com)
+
+	First cut at ANSI-style exception handling (using
+	syntax and semantics of Stroustrup 2nd ed).
+	THIS IS WORK IN PROGRESS!
+	* cp-tree.h:  Declare flag_ansi_exceptions.
+	* gplus.gperf:  Add 'throw' (for ANSI exception handling),
+	and update private/protected/public from (old) cp-lex.c.
+	* cp-hash.h:  New file, generated from gplus.gperf.
+	* cp-lex.c: #include cp-hash.h, instead of requiring
+	manual cut-and-paste when keywords are changed.
+	* cp-lex.c:  Commented out some extern declarations that
+	were conflicting with inlines in cp-input.c.
+	Hooks for ANSI-style exception handling.
+	* cp-parse.y:  Parse ANSI-style exception stuff.
+	* cp-decl2.c:  Define new flag flag_ansi_exceptions.
+	* cp-decl2.c (finish_table):  Off-by-one error in
+	calculating index type.
+	* clus-decl2.c (finish_vtable_vardecl):  Add missing
+	TREE_OPERAND to get dossier decl.
+	* cp-except (cplus_expand_start_except):  Allow NULL name,
+	since there is no distinguished name for ANSI exceptions.
+	* cp-except (cplus_expand_raise):  Too few
+	parameters to expand_expr; add them.
+	* cp-except.c:  New functions for ANSI exceptions:
+	cplus_exception_name, ansi_exception_object_lookup,
+	cplus_expand_throw, ansi_expand_start_catch.
+	These are heavily hacked from similar old functions.
+
+	Try to make -fdossier work better (but more work is needed).
+	(Especially, generate fewer unneeded descriptors.)
+	* cp-class.c (add_virtual_function, finish_struct):  Do not
+	create a vtable just because of -fdossier.
+	* cp-gc.c:  Each type points to an array of fields,
+	instead of an array of pointers to fields.  Ditto for methods.
+	This saves one pointer per field or method by removing
+	unneded extra indirection.  Also other tweaks to save space.
+	* cp-decl.c (init_decl_processing):  Add length of
+	field and method arrays to descriptors, instead of
+	relying on NULL-termination (since we no longer have
+	the extra pointer array).
+	Make the parameter count and required count of
+	method descriptors be shorts.
+	* cp-method.c:  Remove no-longer-needed functions
+	build_i_desc_overload and build_m_desc_overload.
+
+	Other C++ fixes:
+	* cp-dbxout.c (dbxout_symbol):  Class types were
+	emitting only a "t" spec which made gdb unhappy.
+	Kludged it so that it once more emits "Tt".
+	* cp-tree.c (lang_output_debug_info):  Do emit debugging
+	info if this implementation file corresponds the the
+	type's interface, even if nothing is written.

+	(override_options): If -msoft-float, 'f' constraint picks GP
+	registers.
+
+	* t-decrose (collect): Use ALL_CFLAGS instead of CFLAGS, since this
+	gets the shared library flags in x-decrose.

+	doesn't clobber the input argument by turning it into a
+	define_expand, and using a parallel operation including the
+	necessary clobber's.
+	(abssi2, ffssi2, ffssi2_internal): Use the 'd' constraint which only
+	matches the integer registers, rather than 'r' which can match
+	floating point registers as well.

+	* tm-mips-news.h (CPP_SPEC): Add -Dnews7300, -Dsony_news, -Dmips,
+	and -Dhost_mips.

+
+	* cp-class.c (add_method): when adding a new constructor or

+
+	* expr.c (store_field): Handle case where we are storing into a BLKmode

+
+	* tm-mips.h (target_flags): Delete second declaration.
+	(MASK_G0, MASK_G1, MASK_G2): Delete, since -G xx now works to set

+	* cp-pt.c (tsubst): For char_type_node, just build variant and
+	return it.
+	(tsubst, case FUNCTION_DECL): Walk methods more efficiently.
+
+	* cp-pt.c (overload_template_name): Push a binding level, to

+	non-null, even if the name doesn't match.
+	(build_lang_decl): If new decl node is TREE_PERMANENT, make sure the

+	(pushlevel):  Fixed bug which caused scope of tagged types to be
+	incorrectly assigned to the outermost {} block of functions rather
+	than to the outermost binding contours of functions.
+	(pushtag):  Revised to clarify code used to find applicable
+	binding level for a tagname.
+	Set TYPE_CONTEXT of new tagged type so that dwarfout.c can tell
+	file-scope tagged types from non-file-scope tagged types.
+	Create a NULL-named TYPE_DECL node for each new tagged type
+	(even incomplete ones).
+	(finish_struct, finish_enum): Don't create NULL-named
+	TYPE_DECL nodes for complete tagged types.  (This is now done in
+	`pushtag' for *all* new tagged type declarations and definitions.)
+
+	* toplev.c (compile_file):  Adjust conditions under which
+	`dwarfout_file_scope_decl' is called during final traversal of
+	the chain of file-scope decls so that it is called also for
+	file-scope TYPE_DECLs.

+
+	* out-i860.c (output_fp_move_double, find_addr_reg):  Add return stmts

+	(output_delayed_branch):  Fix test for CONST_INT values which must be
+	loaded in two instructions (as two halves).
+	(function_epilogue):  Remove ASM_OUTPUT_EPILOGUE_SUFFIX.  (Superceeded
+	by ASM_DECLARE_FUNCTION_SIZE in varasm.c.)

+	avoid bogus warnings from the MIPS C compiler.
+
+	* cccp.c (fancy_abort): Make this global again, so that

+	which have a different internal form, and convert them to a form
+	that can be recognized.

+
+	* toplev.c (main): If -G is used, set g_switch_set to true, and set

+	case where setup_parse is 0.
+	(tsubst): Check for several common values that won't be modified by
+	substitutions.
+	(tsubst, case FUNCTION_DECL): Don't return type passed if it has a
+	non-null context that might need fixing.  Process that context while
+	building up the new decl node; use it to notify build_decl_overload
+	that we've got a method rather than a function.
+	(tsubst, case METHOD_TYPE): Handle like FUNCTION_TYPE; enhance that
+	case to handle TYPE_METHOD_BASETYPE when set.
+	(unify): Increment value pointed to by nsubsts, not the pointer

+	SELECT_CC_MODE to see if we should try to change the mode of the
+	COMPARE and its result.

+Sun Oct 20 04:37:21 1991  Michael Tiemann  (tiemann at cygnus.com)
+
+	* cp-decl.c (grokfndecl): Use DECL_NAME, not DECLARATOR at end of

+
+Sat Oct 19 17:30:23 1991  Michael Meissner  (meissner at osf.org)
+
+	* tm-mips.h (GP_REG_OR_PSEUDO_P): New macro to make sure a reg or
+	pseudo reg during reload will eventually be a GP register for use as
+	a base or index register.  This fixes a bug where a FP register
+	could be used as a base or index register in some cases after

+
+	* jump.c (unsigned_condition, signed_condition): New functions.
+
+	* configure (vax): Set tm_file to tm-vax.h so "configure vax-dec-bsd"
+	works.
+
+	* combine.c (subst, case PLUS, MINUS): Remove some simplifications
+	from here.
+	* cse.c (simplify_binary_operation, case PLUS, MINUS): Put these
+	simplifications here.
+	Strip off CONST when looking for some simplifications.
+	Add code to simplify (a - (a - b)).

+Fri Oct 18 09:10:43 1991  Michael Tiemann  (tiemann at cygnus.com)
+
+	* cp-parse.y (stmts): Fix parsing rules to match C++ semantics
+	better (and hence give the compiler better error recovery).
+
+Thu Oct 17 19:31:15 1991  Ken Raeburn  (raeburn at cygnus.com)
+
+        * cp-pt.c (tsubst): For NEGATE_EXPR, call build1, not build.
+        Handle NOP_EXPR likewise.
+        (unify, case TEMPLATE_CONST_PARM): Copy value to permanent obstack.
+
+        * cp-method.c (PARM_CAN_BE_ARRAY_TYPE): If not already defined,
+        define it to be 1.
+        (build_overload_name): Test to see if it's nonzero, rather than
+        whether it's defined; this permits compilation options to disable
+        it, but leave it enabled by default.  Add one to the array size,
+        since the value retrieved appears to be the maximum index, not the
+        true array size.
+
+Thu Oct 17 19:15:37 1991  Mark Eichin  (eichin at tweedledumber.cygnus.com)
+
+        * cp-pt.c (instantiate_class_template):  has an argument to
+        indicate whether to setup for parsing or not. (All existing cases
+        did a feed input, but if we are trying to set up intermediate nodes
+        while waiting for the parser to return to a template_instantiate
+        site we need to suppress the parsing part of it, which will get
+        redone later.)
+        (tsubst): under case UNINSTANTIATED_P_TYPE, actually instantiate any
+        class templates that are needed for function return values, and set
+        them up as pending templates to be run later.
+
+        * cp-parse.y (primary): since build_x_function_call doesn't
+        require a complete type any more in certain cases, we instantiate
+        any pending templates and then require_complete_type on the
+        remainder. 
+
+        * cp-typeck.c (build_function_call_real): added an argument to
+        optionally skip the require_complete_type... implicit template
+        instantiation has to be postponed, so we won't get a complete type
+        until the parser can grab it.
+
+        * cp-call.c (build_overload_call_real): added an argument do
+        allow choice of build_function_call_maybe or build_function_call
+        based on whether we thought we would require a complete type out of
+        build_function_call. 
+
+Wed Oct 16 09:06:57 1991  Tom Wood  (wood at dg-rtp.dg.com)
+
+	* c-decl.c (store_parm_decls): Fix and disable recording the arg
+	type list for the function indicating the number of arguments.
+	* c-typeck.c (self_promoting_args_p): Allow the arg type to be null.
+
+	* expmed.c (store_bit_field, extract_bit_field): Add checks for
+	MEM_IN_STRUCT_P if the structure reference is a MEM.
+
+Tue Oct 15 18:37:50 1991  Ken Raeburn  (raeburn at cygnus.com)
+
+        * cp-call.c (build_overload_call): If template match fails, still
+        set function field of candidate structure, and set bad_arg field to
+        new magic number -4 to indicate failed type unificiation.
+
+        * cp-class.c (add_method): Call make_function_rtl only if not
+        processing a template declaration.
+
+        * cp-tree.def: New node type, UNINSTANTIATED_P_TYPE, for
+        parameterized types that haven't had parameters filled in yet.
+        Looks like a type node.
+
+        * cp-decl.c (struct binding_level): New flag indicating any name
+        should be accepted when looked up at this level.  This is a kludge
+        to try to deal with methods of parameterized types.
+        (declare_uninstantiated_type_level): Set it.
+        (uninstantiated_type_level_p): Return it.
+        * cp-class.c (pushclass): If the "class" type is
+        UNINSTANTIATED_P_TYPE, flag it in the new binding level.
+
+        * cp-decl.c (push_overloaded_decl): New argument to indicate
+        whether the decl should be forgotten when the current level is
+        exited.  Callers changed.
+        (push_overloaded_decl_top_level): Ditto.
+        (dont_forget_overload): Deleted.
+        (push_overloaded_decl_1): New fn; like push_overloaded_decl, but
+        never forgets.  Intended only for use by auto_function macro.
+        (auto_function): Use it.
+
+        * cp-decl.c (print_binding_level): Print type-shadowed field at
+        each level.  Skip fields with no values.
+
+        * cp-decl.c (adjust_type_value): Use SET_IDENTIFIER_TYPE_VALUE,
+        not set_identifier_type_value.
+
+        * cp-decl.c (pushdecl): Undo Oct 4 back-out of previous change.
+        Set type value of name of passed decl, instead of name of type in
+        passed decl.
+        (pushdecl_top_level): Search type-shadowed fields of outer binding
+        levels, munging outermost one if found to cause it to "restore" the
+        new global value.
+
+        * cp-decl.c (push_overloaded_decl): Don't punt second or later
+        templates of a given name.
+
+        * cp-decl.c (start_decl): Template-handling code moved up, to
+        cope better with variable declarations.  Don't check for incomplete
+        type or constructor requirements when processing template.
+
+        * cp-decl2.c (build_push_scope): If passed error mark node, just
+        return it.
+        (constructor_name): Handle UNINSTANTIATED_P_TYPE.
+
+        * cp-lex.c (identifier_type): Don't return PTYPENAME for function
+        template name.
+
+        * cp-method.c (report_type_mismatch): New magic bad-arg value -4
+        indicates type unification failure.
+        (build_overload_name, case UNINSTANTIATED_P_TYPE): Handle like other
+        template-related types that shouldn't get visibility outside the
+        compiler.
+
+        * cp-parse.y (template_type): Use IDENTIFIER_TYPE_VALUE from
+        name, if expansion doesn't happen.
+        (tmpl.1, tmpl.2): Now type <ttype>.  Value is null or return value
+        from instantiate_class_template.
+        (template_instantiation): Always put copy of decl in global scope.
+        Use pushdecl_top_level instead of setting IDENTIFIER_GLOBAL_VALUE
+        slot.
+        (LC): If type has been or is being defined, push a new type with the
+        same name, to avoid conflict.
+        (try_for_typename): New type <itype>.  Value is non-zero iff type to
+        be pushed uses no template parms and isn't error_mark_node.
+        (scoped_id): Return error_mark_node for template parameter uses, and
+        leave error_mark_node alone.  Only pop class if try_for_typename
+        value is non-zero.
+        (scoped_typename): Ditto.
+
+        * cp-pt.c (end_template_decl): If template decl/class head arg is
+        null, punt.  For non-type templates that didn't come in as template
+        decls, clear public flag.  Such cases shouldn't arise any more; just
+        put in abort call for now until we're sure.  Comment out code for
+        forcibly removing temporary values of template type parms; Michael
+        broke the code and fixed the original problem.  Handle error case
+        where decl to be pushed might be null.
+        (coerce_template_parms): Handle arg list as TREE_VEC as well as
+        TREE_LIST.  If arg list uses template parms, return
+        UNINSTANTIATED_P_TYPE node.
+        (uses_template_parms, case UNINSTANTIATED_P_TYPE): Return 1.
+        (instantiate_class_template): Now returns tree -- error_mark_node or
+        NULL_TREE or class type; callers and decls changed.  Assign

+
+	* All cplus-* files: Change the representation of the C++
+	inheritance lattice for types.  There is no longer such a thing as a
+	classtype_variant.  Instead, types all have their own lattices
+	accessed via their CLASSTYPE_ASSOC field.
+
+	* cplus-tree.h (lang_type): Delete fields OFFSET,
+	MAIN_CLASS_VARIANT, NEXT_CLASS_VARIANT, VIA_PUB_OR_VIRT.

+	the assoc for the type.
+	(CLASSTYPE_VIA_*, SET_CLASSTYPE_VIAS): Deleted.
+	(CLASSTYPE_OFFSET*): Deleted.
+	(CLASSTYPE_N_BASECLASSES): Now uses type's assoc.  TYPE_BASETYPES
+	field is unused.  Next change will make TYPE_BASETYPES hold the
+	assoc field.
+	(CLASSTYPE_VBASE_SIZE): Use slot in TYPE_LANG_SPECIFIC instead of
+	sneaking it into the TREE_TYPE field of the basetypes.
+
+	(ASSOC_TYPE): Deleted.  Now use ASSOC_VALUE everywhere.
+	(ASSOC_{BASETYPE,BASETYPES}): New macros.  Both are operations on
+	assocs and return assocs.
+	(CLASS_ASSOC_BASETYPE): New macro.  This performs roughly the same
+	function that CLASSTYPE_BASECLASS used to, but it retains no assoc
+	info in the type it returns.
+	(ASSOC_NEXT_ASSOC): New macro used for traversing assoc chains built
+	up by search routines.
+	(ASSOC_VIA_{PUBLIC,VIRTUAL}): New macros for accessing inheritance
+	information.  CLASSTYPE_VIA_{PUBLIC,VIRTUAL} no longer used.
+	(ASSOC_CID): New macro.

+	(DECL_ANON_UNION_ELEM): Deleted.  Now anonymous union decls are
+	distinguished as FIELD_DECLs with NULL DECL_NAMEs and UNION_TYPE
+	types.
+
+	(DERIVED_FROM_P): New macro.  Change calls that testing inheritance
+	relationships (get_base_type and get_base_distance) to use this macro.
+
+	* cplus-type2.c (basetype_or_else): Change interface to use/return an
+	assoc instead of a type.  Change name to base_assoc_or_else.
+
+	* cplus-tree.c (build_classtype_variant): Deleted.
+	(copy_type_lang_specific): Deleted.
+	* all cplus-* files: Everything that used to use CLASSTYPE_OFFSET on
+	types now uses ASSOC_OFFSET on assocs.
+
+	* cplus-class.c (propagate_basetype_offsets): Change interface to use
+	assocs instead of types.  Change name to propagate_assoc_offsets.
+	* cplus-search.c (get_base_type): Ditto; name changed to

+	({build,free}_mi_matrix): Ditto.
+	* cplus-init.c (expand_aggr_init_1): Ditto.

+	(build_virtual_init): Ditto.
+	* cplus-class.c (build_class_init_list): Rewritten to build list with
+	assoc entries instead of types.  Also, use new macro
+	ASSOC_BASEINIT_MARKED instead of CLASSTYPE_MARKED6.
+	(finish_base_struct): New argument ASSOCS is the list of assocs that
+	describe the basetypes of T.
+
+	* cplus-tree.c (make_lang_type): Always initialize
+	CLASSTYPE_VBASE_SIZE to integer_zero_node.  To test if a class has
+	virtual baseclasses, test CLASSTYPE_VBASECLASSES, not
+	CLASSTYPE_VBASE_SIZE.
+
+	* cplus-class.c (finish_struct): Rewritten to use assocs instead of
+	types where appropriate.
+
+	* cplus-search.c (get_base_distance): Change interface to use assocs
+	or types.  Also, PATH_PTR argument is now an assoc chain, not a
+	TREE_LIST.  Algorithm to find leftmost path is now more efficient.
+	(compute_visibility): Uses assoc chain instead of TREE_LIST of
+	types.
+	(recursive_bounded_basetype_p): New function.
+	(dfs_walk, dfs_* functions): Change to be called with assocs instead
+	of types.
+	(breadth_first_search, all bfs_*): Ditto.
+	cplus-tree.c (reverse_path): New function.  Like nreverse, but works
+	on assoc chains.
+
+	* cplus-class.c (build_vtable, prepare_fresh_vtable,
+	modify_vtable_{entries,entry},): Change interfaces to use assocs
+	instead of types.  Use macro ASSOC_VTABLE_PATH_MARKED on the assocs
+	instead of CLASSTYPE_MARKED3.  Use macro ASSOC_NEW_VTABLE_MARKED on
+	the assocs instead of CLASSTYPE_MARKED4.
+
+	* cplus-dbxout.c: Now needs to know more about assocs.  When assocs
+	are put in the TYPE_BASETYPEs field, it should not need to know
+	about lang_type.
+
+	* cplus-decl.c (xref_tag): Rewritten to build proper assoc lists.  No
+	longer builds basetype lists.
+	(finish_function): Make `flag_no_inline' really take effect.
+
+	* cplus-tree.c (make_assoc): Changed for new assoc structure.  The
+	fields in assocs are now: VALUE (pointer to TYPE that this assoc is
+	for), OFFSET (the byte offset of this basetype in the whole object),
+	VTABLE (the virtual function table that should be used to initialize
+	objects controlled by this assoc), VIRTUALS (the virtual functions
+	to use for initializing VTABLE), BASETYPES (a TREE_VEC of basetypes
+	that this assoc has, or NULL_TREE if none), NEXT_ASSOC (a temporary
+	slot used to point to the next assoc in an assoc chain),
+	VIA_{PUBLIC,VIRTUAL} bits saying whether this assoc is a basetype of
+	its parent via public or virtual inheritance.
+
+	* cplus-ptree.c (print_lang_type): Modified as necessary to cope with
+	new inheritance structure.
+
+	* cplus-search.c (get_base_type_1): This function was unused and
+	wrong.  Deleted.
+
+	* cplus-tree.c (layout_basetypes): Take new arg ASSOCS.  Layout the
+	basetypes my modifying the assocs, not the types.
+	(layout_vbasetypes): Ditto.
+
+	* all cplus-* files: Removed dead code, unused variables, and change
+	asserts where appropriate.
+
+	* all cplus-* files: DECL_VIRTUAL_P is no longer used as a truth test
+	for whether or not a function is virtual.  Use a test for non-NULL
+	DECL_VINDEX instead.

+
+	* expr.c (c_strlen): New function; determines strlen of string const.
+	(expand_builtin, cases BUILT_IN_STRCMP, BUILT_IN_STRCPY): Call it

+	(*extend*): Rework these patterns.  Don't accept memory input

+
+	* cplus-decl.c (start_decl): When constructing a decl tree for a
+	function template, copy last_function_parms to permanent storage,
+	and save it as the function argument list.  Call build_lang_decl
+	instead of build_decl, instead of duplicating the extra work it does.
+	Set `overloaded' flag to 1.  Call dont_forget_overload, so the
+	template decl won't get discarded.
+	Also deleted some commented-out code.
+
+	* cplus-pt.c (uses_template_parms, cases VAR_DECL, FUNCTION_DECL):
+	Give a warning if template parms are only used in places where they

+
+	* genemit.c (gen_expand, main): Change FAIL macro to be a simple

+
+	* cplus-class.c (add_virtual_function): Memoize the first 256
+	virtual function table index nodes (0x80000001, 0x80000002, etc.).

+	* cplus-tree.c (layout_basetypes): Same change.

+	(FULL_PROTOTYPES, NO_CONST_IN_SYSCALL): Define to get protoize
+	to compile cleanly.
+
+	* osf-main.c (new file): Provide simple constructor, destructor
+	capability to be linked into gnulib.
+
+	* collect-osf.c (various): General rewrite to improve speed and
+	portability.
+
+	* Makefile.in (CPLUS_OBJS): If CPLUS_INPUT is defined to be
+	cplus-input.o, compile it separately to work around problems with
+	bootstraping when it is included in cplus-lex.c.
+	(STAGESTUFF): Use $(LANGUAGES) instead of hard coded list of
+	languages, so make-xxx file can override, and provide others.
+	(gnulib2.ready): Make gnulib2 depend on all LANGUAGES targets, so
+	that if a target needs something else built, such as mips-tfile, it
+	will be.
+	(mostlyclean): Add missing -f to rm.
+	(install-dir): Use test to see if the directory exists before trying
+	to create it, and fail if the mkdir fails.
+	(install-headers): ditto.
+	(stage?, risky-stage?): ditto.
+	(install-cross): Install collect and mips-tfile if they are present.
+
+	* mips-tfile.c (toplevel, main): Add -I file option, which renames
+	the original output file to the given file.
+
+	* cplus-lex.c (toplevel): Include <assert.h> instead of "assert.h"
+	in order to avoid problems when including cplus-input.c, which also
+	uses <assert.h>.
+
+	* cplus-pt.c (toplevel): Move include of config.h before obstack.h
+	in case config.h defines some macros obstack.h uses such as
+	__PTR_TO_INT.
+
+Tue Jul 23 13:15:43 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* xm-i386.h, xm-i860.h, xm-spur.h, xm-tahoe.h: Use __builtin_alloca.
+
+Tue Jul 23 12:26:01 1991  Michael Tiemann  (tiemann at cygint.cygnus.com)
+
+	* function.c (instantiate_virtual_regs_1): Change dubious code that
+	used to assign NEW to XEXP (x, 1) regardless of whether
+	validate_change accepted it to instead set XEXP (x, 0) back to OLD.
+	I.e., if the rtx is out of range and OBJECT is NULL, don't make any
+	change at all.
+
+	* out-sparc.c (compute_frame_size): If a function has any
+	stack-local objects, it's frame size is non-zero and space must be
+	reserved for the register window.
+
+	* loop.c (loop_optimize): Use get_max_uid to compute max_uid_for_loop.
+
+	* fold-const.c (size_int): Extend SIZE_TABLE's range from
+	0..HOST_BITS_PER_INT-1 to 0..2*HOST_BITS_PER_INT.
+
+	* integrate.c (expand_inline_function): Add minor efficiency
+	hack to not free all the temp slots as parameters are passed
+	from "caller" to "callee".
+
+	* integrate.c (expand_inline_function): If the inline function
+	returns its value via a structure_value_addr, we must prepare for
+	this to take place, even if the value is ignored by the caller.
+
+	* tm-decstatn.h (SIZE_TYPE): Define this to be "unsigned int".
+
+	* emit-rtl.c (try_split): If `split_insns' actually returns a SEQ
+	which is isomorphic to PAT, return TRIAL.
+
+	* out-sparc.c (eligible_for_epilogue_delay): FP register moves are
+	only eligible for leaf-function epilogue delay slots.
+
+Tue Jul 23 11:52:50 1991  Michael Meissner  (meissner at geech.gnu.ai.mit.edu)
+
+	* dbxout.c (dbxout_symbol): Correct typo in getting static member
+	names.  The problem is DECL_ASSEMBLER_NAME returns a tree, and not a
+	char *.
+
+Tue Jul 23 07:10:41 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* varasm.c (immed_double_const): Use CONST_INT if MODE fits within
+	HOST_BITS_PER_INT, not BITS_PER_WORD.
+
+Mon Jul 22 21:37:03 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* fold-const.c (fold): Always preserve type after using const_binop.
+
+Mon Jul 22 18:34:55 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* reload1.c (reload): Fix typo in condition for reg_equiv_address
+	being set from reg_equiv_memory_loc; had X instead of XEXP (X, 0).
+
+Mon Jul 22 15:25:48 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* gcc.c (process_command): -xnone turns off any -x option.
+
+	* tree.c (copy_chain): Deleted.
+	* integrate.c (copy_decl_tree): Use copy_list and copy_node.
+
+Mon Jul 22 11:35:47 1991  Michael Tiemann  (tiemann at pogo.gnu.ai.mit.edu)
+
+	* tree.c, tree.h: Fix typos in Jul 22 merge.
+
+Mon Jul 22 08:51:47 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* jump.c (thread_jumps): Don't set CHANGED if the jump's label isn't
+	changing.
+
+Mon Jul 22 02:37:23 1991  Michael Tiemann  (tiemann at pogo.gnu.ai.mit.edu)
+
+	* version.c: Bumped to 1.94 because of significant changes to
+	cplus-* files.
+
+Sun Jul 21 18:45:57 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* toplev.c (rest_of_compilation):
+	Save and restore DECL_INITIAL if we use save_for_inline_copying.
+	* integrate.c (save_for_inline_copying): Really copy DECL_INITIAL.
+	Calling integrate_decl_tree doesn't do it; deleted that call.
+	(copy_decl_tree): New function.
+
+	* integrate.c (integrate_decl_tree): Renamed from copy_decl_tree.
+	(integrate_parm_decls): Renamed from copy_parm_decls.
+
+	* tree.c (copy_chain): New function.
+
+Sun Jul 21 06:43:23 1991  James Van Artsdalen  (james at bigtex.cactus.org)
+
+	* i386.md (tstsi): Add comment noting potential -m486 enhancement.
+	(SImode push): With -m486, don't push from MEM.
+	(addsi3): Don't use lea for three operand add if -m486.
+	(ashlsi3): Don't use lea for shift of 1 if -m486.
+	(zero_extendhisi2,zero_extendqihi2,zero_extendqisi2): If dest is
+	%eax, or if -m486, AND is faster than MOVZX.
+
+Sun Jul 21 06:27:33 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* expmed.c (store_fixed_bit_field): Pass actual bit position (including
+	offset) to get_best_mode; also limit mode size to BITS_PER_WORD.
+	Use failure of get_best_mode to indicate that field spans word 
+	boundary.
+	Pass actual bit position to store_split_bit_field.
+	(store_split_bit_field): Accept actual bit position, hence handing
+	bitpos > BITS_PER_WORD.
+	Abort if BITPOS and BITSIZE don't cross exactly one word boundary.
+	Pass offset to store_fixed_bit_field; if register, use operand_subword;
+	else adjust offset for second word.
+	(extract_{fixed,split}_bit_field): Likewise.
+
+Sun Jul 21 06:11:55 1991  Michael Tiemann  (tiemann at cygint.cygnus.com)
+
+	* All cplus-* files: DECL_VIRTUAL_P is no longer applied to
+	FUNCTION_DECLs.  Instead, to test if a function is virtual or not,
+	it suffices to test whether its DECL_VINDEX is non-NULL.  We use
+	ERROR_MARK_NODE as the placeholder for a FUNCTION_DECL we know will
+	be virtual, but for which we don't yet know the actual index.
+
+	* cplus-decl.c (define_function): Don't set up DECL_ASSEMBLER_NAME
+	until after having the chance to call through PFN.  Since `pushdecl'
+	now keys off of DECL_ASSEMBLER_NAME, we don't want to create
+	inadvertent aliases between builtin and library functions.
+
+	* cplus-typeck.c (build_modify_expr): We don't need to build a
+	SAVE_EXPR for a WITH_CLEANUP_EXPR.
+	(unary_complex_lvalue): For good measure, know how to deal with a
+	WITH_CLEANUP_EXPR inside a SAVE_EXPR.
+
+	* cplus-pt.c (uses_template_parms): Add handler for ARRAY_TYPE.
+
+	* cplus-method.c (do_inline_function_hair): Use TYPE_METHODS instead
+	of CLASSTYPE_METHOD_VEC for traversing all methods when looking for
+	inline functions.
+
+	* cplus-class.c (finish_struct_methods): Fix fencepost error if
+	there were no member functions except for ctors/dtors.
+
+Sun Jul 21 06:19:01 1991  James Van Artsdalen  (james at bigtex.cactus.org)
+
+	* tree.h, output.h (current_function_calls_longjmp): New variable.
+	* function.c (top level): Define it.
+	(push_function_context): Save it.
+	(pop_function_context): Restore it.
+	(init_function_start): Initialize it.
+
+	* calls.c (expand_call): Set current_function_calls_longjmp if
+	this call is to `longjmp'.
+
+	* flow.c, global-alloc.c: Include output.h so that
+	FRAME_POINTER_REQUIRED can use current_function_calls_*.
+	* Makefile.in (flow.o,global-alloc.o): Includes output.h.
+
+	* rtl.h (FUNCTION_FLAGS_CALLS_LONGJMP): New macro.
+
+	* integrate.c (initialize_for_inline): Record
+	current_function_calls_lonjmp in `function_flags'.
+	(output_inline_function): Set current_function_calls_longjmp if
+	the inline code calls longjmp.
+
+	* function.h (struct function): New field `calls_longjmp'.
+
+	* out-i386.c (simple_386_epilogue):  Add function description.
+	Return 0 if NON_SAVING_SETJMP && `setjmp' is called in function.
+
+	* tm-i386v.h (NON_SAVING_SETJMP): New macro.
+	(FRAME_POINTER_REQUIRED): New macro.
+
+Sat Jul 20 12:25:56 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* tm-m88k.h (OPTIMIZATION_OPTIONS): Don't change flag_signed_bitfields.
+
+	* cccp.c (include_defaults) Use LOCAL_INCLUDE_DIR macro instead
+	of "/usr/local/include".  Provide default definition.
+
+	* cccp.c (include_defaults) Added INCLUDE_DEFAULTS macro to
+	provide complete control over default include directories.
+	Delete the special case for VMS.
+	* xm-vms.h (INCLUDE_DEFAULTS): Defined.
+
+	* proto-man: Renamed from proto-unproto.1.
+
+	* final.c (final_scan_insn): Do ASM_OUTPUT_LOOP_ALIGN only for real loop.
+
+Sat Jul 20 05:34:13 1991  Michael Tiemann  (tiemann at cygint.cygnus.com)
+
+	* tree.h (tree_type): Use the MAXVAL slot for TYPE_METHODS.
+	* cplus-class.c (finish_struct): Methods are now chained with
+	TREE_CHAIN and placed in the TYPE_METHODS of their _TYPE node.
+	* cplus-dbxout.c (dbxout_type_methods): Use this fact, instead of
+	using more C++-specific knowledge.
+
+	* cplus-decl.c (init_decl_processing): Variable
+	`const_ptr_type_node' was not being initialized.  Same with
+	`const_string_type_node'.
+
+	* tree.h (DECL_PRINT_NAME): Marked for death.
+	(DECL_ASSEMBLER_NAME): Changed from a char* to a tree node.
+	All front-end files changed as necessary.
+
+	* cplus-tree.h (DECL_ORIGINAL_NAME): Deleted.  Now we use
+	DECL_NAME.
+	(DECL_NAME): No longer means the mangled name.  Now we use
+	DECL_ASSEMBLER_NAME for that purpose.
+	All cplus-* files changed as necessary.
+
+	* cplus-tree.c (lang_printable_name): Use a ring-buffer to hold
+	printable names instead of DECL_PRINT_NAME slot of a _DECL node.
+
+	* collect2.c: #define COLLECT, and let config.h provide definition
+	of macros.
+
+See file ChangeLog.3.
