This moves the gdb-specific obstack code -- both extensions like
obconcat and obstack_strdup, and things like auto_obstack -- to
gdbsupport.

This commit adds a flag to the ptype command in order to print the
offsets and sizes of struct members using the hexadecimal notation. The
'x' flag ensures use of the hexadecimal notation while the 'd' flag
ensures use of the decimal notation. The default is to use decimal
notation.
Before this patch, gdb only uses decimal notation, as pointed out in PR
gdb/22640.
Here is an example of this new behavior with hex output turned on:
(gdb) ptype /ox struct type_print_options
/* offset | size */ type = struct type_print_options {
/* 0x0000: 0x0 | 0x0004 */ unsigned int raw : 1;
/* 0x0000: 0x1 | 0x0004 */ unsigned int print_methods : 1;
/* 0x0000: 0x2 | 0x0004 */ unsigned int print_typedefs : 1;
/* 0x0000: 0x3 | 0x0004 */ unsigned int print_offsets : 1;
/* 0x0000: 0x4 | 0x0004 */ unsigned int print_in_hex : 1;
/* XXX 3-bit hole */
/* XXX 3-byte hole */
/* 0x0004 | 0x0004 */ int print_nested_type_limit;
/* 0x0008 | 0x0008 */ typedef_hash_table *local_typedefs;
/* 0x0010 | 0x0008 */ typedef_hash_table *global_typedefs;
/* 0x0018 | 0x0008 */ ext_lang_type_printers *global_printers;
/* total size (bytes): 32 */
}
This patch also adds the 'set print type hex' and 'show print type hex'
commands in order to set and inspect the default behavior regarding the
use of decimal or hexadecimal notation when printing struct sizes and
offsets.
Tested using on x86_64.

Note that the ptype information printed for types described
via pure DWARF debug info is slightly less informative as
the one printed when the information is encoded in the type's
name, via the GNAT encoding. As a result, the output in
the case of DWARF-described fixed point types is slightly
different. In pratice, this is no real loss because the information
not available in DWARF has no bearing on how the type is actually
stored in memory.

This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

This commit implements the pahole-like '/o' option for 'ptype', which
prints the offsets and sizes of struct fields, reporting whenever
there is a hole found.
The output is heavily based on pahole(1), with a few modifications
here and there to adjust it to our reality. Here's an example:
/* offset | size */ type = struct wer : public tuv {
public:
/* 32 | 24 */ struct tyu {
/* 32:31 | 4 */ int a1 : 1;
/* 32:28 | 4 */ int a2 : 3;
/* 32: 5 | 4 */ int a3 : 23;
/* 35: 3 | 1 */ char a4 : 2;
/* XXX 3-bit hole */
/* XXX 4-byte hole */
/* 40 | 8 */ int64_t a5;
/* 48:27 | 4 */ int a6 : 5;
/* 48:56 | 8 */ int64_t a7 : 3;
/* total size (bytes): 24 */
} a1;
/* total size (bytes): 56 */
}
A big part of this patch handles the formatting logic of 'ptype',
which is a bit messy. The code to handle bitfield offsets, however,
took some time to craft. My thanks to Pedro Alves for figuring things
out and pointing me to the right direction, as well as coming up with
a way to inspect the layout of structs with bitfields (see testcase
for comments).
After many discussions both on IRC and at the mailing list, I tried to
implement printing vtables and inherited classes. Unfortunately the
code grew too complex and there were still a few corner cases failing
so I had to drop the attempt. This should be implemented in a future
patch.
This patch is the start of a long-term work I'll do to flush the local
patches we carry for Fedora GDB. In this specific case, I'm aiming at
upstreaming the feature implemented by the 'pahole.py' script that is
shipped with Fedora GDB:
<https://src.fedoraproject.org/rpms/gdb/blob/master/f/gdb-archer.patch#_311>
This has been regression-tested on the BuildBot. There's a new
testcase for it, along with an update to the documentation. I also
thought it was worth mentioning this feature in the NEWS file.

GDB currently does not track types defined in classes. Consider:
class A
{
public:
class B
{
public:
class C { };
};
};
(gdb) ptype A
type = class A {
<no data fields>
}
This patch changes this behavior so that GDB records these nested types
and displays them to the user when he has set the (new) "print type"
option "nested-type-limit."
Example:
(gdb) set print type nested-type-limit 1
(gdb) ptype A
type = class A {
<no data fields>
class A::B {
<no data fields>
};
}
(gdb) set print type nested-type-limit 2
type = class A {
<no data fields>
class A::B {
<no data fields>
class A::B::C {
<no data fields>
};
};
}
By default, the code maintains the status quo, that is, it will not print
any nested type definitions at all.
Testing is carried out via cp_ptype_class which required quite a bit of
modification to permit recursive calling (for the nested types). This
was most easily facilitated by turning the ptype command output into a
queue. Upshot: the test suite now has stack and queue data structures that
may be used by test writers.

An earlier commit made GDB no longer assume no-debug-info functions
return int. This commit gives the same treatment to variables.
Currently, you can end misled by GDB over output like this:
(gdb) p var
$1 = -1
(gdb) p /x var
$2 = 0xffffffff
until you realize that GDB is assuming that the variable is an "int",
because:
(gdb) ptype var
type = <data variable, no debug info>
You may try to fix it by casting, but that doesn't really help:
(gdb) p /x (unsigned long long) var
$3 = 0xffffffffffffffff # incorrect
^^
That's incorrect output, because the variable was defined like this:
uint64_t var = 0x7fffffffffffffff;
^^
What happened is that with the cast, GDB did an int -> 'unsigned long
long' conversion instead of reinterpreting the variable as the cast-to
type. To get at the variable properly you have to reinterpret the
variable's address manually instead, with either:
(gdb) p /x *(unsigned long long *) &var
$4 = 0x7fffffffffffffff
(gdb) p /x {unsigned long long} &var
$5 = 0x7fffffffffffffff
After this commit GDB does it for you. This is what you'll get
instead:
(gdb) p var
'var' has unknown type; cast it to its declared type
(gdb) p /x (unsigned long long) var
$1 = 0x7fffffffffffffff
As in the functions patch, the "compile" machinery doesn't currently
have the cast-to type handy, so it continues assuming no-debug
variables have int type, though now at least it warns.
The change to gdb.cp/m-static.exp deserves an explanation:
- gdb_test "print 'gnu_obj_1::method()::sintvar'" "\\$\[0-9\]+ = 4" \
+ gdb_test "print (int) 'gnu_obj_1::method()::sintvar'" "\\$\[0-9\]+ = 4" \
That's printing the "sintvar" function local static of the
"gnu_obj_1::method()" method.
The problem with that test is that that "'S::method()::static_var'"
syntax doesn't really work in C++ as you'd expect. The way to make it
work correctly currently is to quote the method part, not the whole
expression, like:
(gdb) print 'gnu_obj_1::method()'::sintvar
If you wrap the whole expression in quotes, like in m-static.exp, what
really happens is that the parser considers the whole string as a
symbol name, but there's no debug symbol with that name. However,
local statics have linkage and are given a mangled name that demangles
to the same string as the full expression, so that's what GDB prints.
After this commit, and without the cast, the print in m-static.exp
would error out saying that the variable has unknown type:
(gdb) p 'gnu_obj_1::method()::sintvar'
'gnu_obj_1::method()::sintvar' has unknown type; cast it to its declared type
TBC, if currently (even before this series) you try to print any
function local static variable of type other than int, you'll get
bogus results. You can see that with m-static.cc as is, even.
Printing the "svar" local, which is a boolean (1 byte) still prints as
"int" (4 bytes):
(gdb) p 'gnu_obj_1::method()::svar'
$1 = 1
(gdb) ptype 'gnu_obj_1::method()::svar'
type = <data variable, no debug info>
This probably prints some random bogus value on big endian machines.
If 'svar' was of some aggregate type (etc.) we'd still print it as
int, so the problem would have been more obvious... After this
commit, you'll get instead:
(gdb) p 'gnu_obj_1::method()::svar'
'gnu_obj_1::method()::svar' has unknown type; cast it to its declared type
... so at least GDB is no longer misleading. Making GDB find the real
local static debug symbol is the subject of the following patches. In
the end, it'll all "Just Work".

The fact that GDB defaults to assuming that functions return int, when
it has no debug info for the function has been a recurring source of
user confusion. Recently this came up on the errno pretty printer
discussions. Shortly after, it came up again on IRC, with someone
wondering why does getenv() in GDB return a negative int:
(gdb) p getenv("PATH")
$1 = -6185
This question (with s/getenv/random-other-C-runtime-function) is a FAQ
on IRC.
The reason for the above is:
(gdb) p getenv
$2 = {<text variable, no debug info>} 0x7ffff7751d80 <getenv>
(gdb) ptype getenv
type = int ()
... which means that GDB truncated the 64-bit pointer that is actually
returned from getent to 32-bit, and then sign-extended it:
(gdb) p /x -6185
$6 = 0xffffe7d7
The workaround is to cast the function to the right type, like:
(gdb) p ((char *(*) (const char *)) getenv) ("PATH")
$3 = 0x7fffffffe7d7 "/usr/local/bin:/"...
IMO, we should do better than this.
I see the "assume-int" issue the same way I see printing bogus values
for optimized-out variables instead of "<optimized out>" -- I'd much
rather that the debugger tells me "I don't know" and tells me how to
fix it than showing me bogus misleading results, making me go around
tilting at windmills.
If GDB prints a signed integer when you're expecting a pointer or
aggregate, you at least have some sense that something is off, but
consider the case of the function actually returning a 64-bit integer.
For example, compile this without debug info:
unsigned long long
function ()
{
return 0x7fffffffffffffff;
}
Currently, with pristine GDB, you get:
(gdb) p function ()
$1 = -1 # incorrect
(gdb) p /x function ()
$2 = 0xffffffff # incorrect
maybe after spending a few hours debugging you suspect something is
wrong with that -1, and do:
(gdb) ptype function
type = int ()
and maybe, just maybe, you realize that the function actually returns
unsigned long long. And you try to fix it with:
(gdb) p /x (unsigned long long) function ()
$3 = 0xffffffffffffffff # incorrect
... which still produces the wrong result, because GDB simply applied
int to unsigned long long conversion. Meaning, it sign-extended the
integer that it extracted from the return of the function, to 64-bits.
and then maybe, after asking around on IRC, you realize you have to
cast the function to a pointer of the right type, and call that. It
won't be easy, but after a few missteps, you'll get to it:
..... (gdb) p /x ((unsigned long long(*) ()) function) ()
$666 = 0x7fffffffffffffff # finally! :-)
So to improve on the user experience, this patch does the following
(interrelated) things:
- makes no-debug-info functions no longer default to "int" as return
type. Instead, they're left with NULL/"<unknown return type>"
return type.
(gdb) ptype getenv
type = <unknown return type> ()
- makes calling a function with unknown return type an error.
(gdb) p getenv ("PATH")
'getenv' has unknown return type; cast the call to its declared return type
- and then to make it easier to call the function, makes it possible
to _only_ cast the return of the function to the right type,
instead of having to cast the function to a function pointer:
(gdb) p (char *) getenv ("PATH") # now Just Works
$3 = 0x7fffffffe7d7 "/usr/local/bin:/"...
(gdb) p ((char *(*) (const char *)) getenv) ("PATH") # continues working
$4 = 0x7fffffffe7d7 "/usr/local/bin:/"...
I.e., it makes GDB default the function's return type to the type
of the cast, and the function's parameters to the type of the
arguments passed down.
After this patch, here's what you'll get for the "unsigned long long"
example above:
(gdb) p function ()
'function' has unknown return type; cast the call to its declared return type
(gdb) p /x (unsigned long long) function ()
$4 = 0x7fffffffffffffff # correct!
Note that while with "print" GDB shows the name of the function that
has the problem:
(gdb) p getenv ("PATH")
'getenv' has unknown return type; cast the call to its declared return type
which can by handy in more complicated expressions, "ptype" does not:
(gdb) ptype getenv ("PATH")
function has unknown return type; cast the call to its declared return type
This will be fixed in the next patch.

Fortran provide types whose values may be dynamically allocated
or associated with a variable under explicit program control.
The purpose of this commit is:
* to read allocated/associated DWARF tags and store them in
the dynamic property list of main_type.
* enable GDB to print the value of a dynamic array in Fortran
in case the type is allocated or associated (pointer to
dynamic array).
Examples:
(gdb) p vla_not_allocated
$1 = <not allocated>
(gdb) p vla_allocated
$1 = (1, 2, 3)
(gdb) p vla_ptr_not_associated
$1 = <not associated>
(gdb) p vla_ptr_associated
$1 = (1, 2, 3)
Add basic test coverage for most dynamic array use-cases in Fortran.
The commit contains the following tests:
* Ensure that values of Fortran dynamic arrays
can be evaluated correctly in various ways and states.
* Ensure that Fortran primitives can be evaluated
correctly when used as a dynamic array.
* Dynamic arrays passed to subroutines and handled
in different ways inside the routine.
* Ensure that the ptype of dynamic arrays in
Fortran can be printed in GDB correctly.
* Ensure that dynamic arrays in different states
(allocated/associated) can be evaluated.
* Dynamic arrays passed to functions and returned from
functions.
* History values of dynamic arrays can be accessed and
printed again with the correct values.
* Dynamic array evaluations using MI protocol.
* Sizeof output of dynamic arrays in various states.
The patch was tested using the test suite on Ubuntu 12.04 64bit.

Based on work from Daniel Jacobowitz <dan@codesourcery.com>
* c-typeprint.c (cp_type_print_method_args): For non-static methods,
print out const or volatile qualifiers, too.
(c_type_print_args): Add parameters show_artificial and language.
Skip artificial parameters when requested.
Use the appropriate language printer.
(c_type_print_varspec): Tell c_type_print_args to skip artificial
parameters and pass language_c.
* dwarf2read.c (die_list): New file global.
(struct partial_die_info): Update comments for name field.
(pdi_needs_namespace): Renamed to ...
(die_needs_namespace): ... this. Rewrite.
(dwarf2_linkage_name): Remove.
(add_partial_symbol): Do not predicate the call to
partial_die_full_name based on pdi_needs_namespace.
Remove call to cp_check_possible_namespace_symbols and associated
outdated comments.
(guess_structure_name): Do not inspect child subprogram DIEs.
(dwarf2_fullname): Update comments.
Use die_needs_namespace to assist in computing the name.
(read_func_scope): Use dwarf2_name to get the DIE's name.
Use dwarf2_physname to get the "linkage name" of the DIE.
(dwarf2_add_member_field): Use dwarf2_physname instead of
dwarf2_linkage_name.
(read_structure_type): For structs and classes, set TYPE_NAME, too.
(determine_class): Remove.
(read_partial_die): Ignore DW_AT_MIPS_linkage_name for all languages
except Ada.
(new_symbol): Unconditionally call dwarf2_name.
Compute the "linkage name" using dwarf2_physname.
Use dwarf2_name instead of dwarf2_full_name for enumerator DIEs.
When determining to scan for anonymous C++ namespaces, ignore
the linkage name.
(dwarf2_physname): New function.
(dwarf2_full_name): Move content to new function and call
that.
(dwarf2_compute_name): "New" function.
(_initialize_dwarf2_read): Initialize die_list.
* gnu-v3-eabi.c (gnu_v3_find_method_in): Remove unused variable
physname.
(gnu_v3_print_method_ptr): Use the physname for virtual methods
without a demangled name.
Print out type information for non-virtual methods.
* linespec.c (decode_line_1): Force ANY string using "::" (or
"." for java) to use decode_compound, and clean up any stray quoting.
If we found a file symtab, re-evaluate whether the remainder is_quoted.
(decode_compound): Stop consuming at an open parenthesis.
Keep template parameters.
Keep any overload information.
Keep keywords like "const".
Remove paren_pointer.
Move is_quoted check from set_flags to here.
Remove #if 0 code from 2000. Ten years is long enough.
(find_method): Before comparing symbol names, canonicalize the string
from the user.
If a specific overload is requested, find it. Otherwise throw an error.
(find_method_overload_end): New function.
(set_flags): Remove.
(decode_compound): Assume that parentheses are matched.
It's a lot easier.
* symtab.c (symbol_find_demangled_name): Add DMGL_VERBOSE flag
to cplus_demangle.
* linespec.c (decode_line_1): Keep important keywords like
"const" and "volatile".
* symtab.h (SYMBOL_CPLUS_DEMANGLED_NAME): Remove.
* typeprint.h (c_type_print_args): Add declaration.
* ui-file.c (do_ui_file_obsavestring): New function.
(ui_file_obsavestring): New function.
* ui-file.h (ui_file_obsavestring): Add declaration.
* valops.c (find_overload_match): Resolve the object to
a non-pointer type.
If the object is a data member, search the object for the member
and return with staticp set.
Use SYMBOL_NATURAL_NAME instead of SYMBOL_CPLUS_DEMANGLED_NAME.
Do not attempt to extract a function name from non-function types.
If the extracted function name and the original name are the same,
we don't have a C++ method.
From Jan Kratochvil <jan.kratochvil@redhat.com>:
* dwarf2read.c (new_symbol <DW_TAG_enumerator>): Call dwarf2_full_name.

Change all references to stdout/stderr to gdb_stdout/gdb_stderr.
Replace all calls to stdio output functions with calls to
corresponding _unfiltered functions (`fprintf_unfiltered')
Replaced calls to fopen for output to gdb_fopen.
Added sufficient goo to utils.c and defs.h to make the above work.
The net effect is that stdio output functions are only directly used
in utils.c. Elsewhere, the _unfiltered and _filtered functions and
GDB_FILE type are used.
In the near future, GDB_FILE will stop being equivalant to FILE.
The semantics of some commands has changed in a very subtle way:
called in the right context, they may cause new occurences of
prompt_for_continue() behavior. The testsuite doesn't notice anything
like this, though.
Please respect this change by not reintroducing stdio output
dependencies in the main body of gdb code. All output from commands
should go to a GDB_FILE.
Target-specific code can still use stdio directly to communicate with
targets.

of create_range_type.
* printcmd.c (ptype_command, ptype_eval, whatis_command,
whatis_exp, maintenance_print_type): Move prototypes and functions
to new typeprint.c.
* printcmd.c (_initialize_printcmd): Move add_com calls for
ptype_command and whatis_command to new typeprint.c.
* ser-bsd.c (serial_open): Remove unused variable sgttyb.
* source.c (find_source_lines): Local variable c only used
when LSEEK_NOT_LINEAR is defined.
* stabsread.c (read_array_type): Use new create_range_type
function.
* stabsread.c (read_range_type): Add new index_type variable and
call new create_range_type function rather than handcrafting
range types.
* symmisc.c (type_print_1): Change usages to LA_PRINT_TYPE.
* symtab.c (typedef_print usages): Use c_typedef_print, renamed.
* symtab.c (type_print_base usages): Use c_type_print_base.
* symtab.c (type_print_varspec_prefix usages): Use
c_type_print_varspec_prefix.
* symtab.c (type_print_method_args usages): Use
cp_type_print_method_args.
* valprint.c: Completely ripped apart and the fragments used
to create c-valprint.c, cp-valprint.c, m2-valprint.c, and
valprint.h. Remaining stuff is language independent.
* value.h (struct fn_field): Forward declare for prototypes.
* value.h (type_print_1): Remove prototype.
* value.h (enum val_prettyprint): Moved to defs.h.
* value.h (typedef_print): Prototype renamed to c_typedef_print.
* value.h (baseclass_offset): Add prototype.
**** start-sanitize-chill ****
* Makefile.in (SFILES_MAINDIR): Add ch-typeprint.c, ch-valprint.c.
* Makefile.in (OBS): Add ch-typeprint.o, ch-valprint.o.
* ch-typeprint.c: New file for language dependent type printing.
* ch-valprint.c: New file for language dependent value printing.
* ch-exp.y (parse_number): Remove prototype and stub function.
* ch-exp.y (decode_integer_literal): Removed unused digits and
temp variables.
* ch-exp.y (convert_float): Completely ifdef out for now.
* ch-exp.y (tokentab2, tokentab3, tokentab4, tokentab5),
ch-lang.c (chill_op_print_tab):
Change from ANSI-obsolescent "const static" to ANSI-conformant
"static const".
* ch-exp.y (yylex): Add unhandled storage class enumeration
literals to switch statement for completeness.
* ch-lang.c (chill_create_fundamental_types): Remove unused
nbytes variable. Change dummy type to 2 bytes to match int.
Handle FT_VOID types gratuituously added to chill DWARF by
compiler. Change FT_CHAR case to generate an TYPE_CODE_CHAR
type rather than a one byte TYPE_CODE_INT type.
* ch-lang.c (chill_language_defn): Add chill_print_type and
chill_val_print.
* ch-lang.h (chill_print_type, chill_val_print): Add prototypes.
