configure doesn't check for sys/types.h any more, but it still tries
to use the result of the check. This removes that use as well.
2013-11-18 Tom Tromey <tromey@redhat.com>
* configure: Rebuild.
* configure.ac: Remove check of HAVE_SYS_TYPES_H.
We don't use the result of checking for unistd.h, so this removes the
check.
2013-11-18 Tom Tromey <tromey@redhat.com>
* configure: Rebuild.
* configure.ac: Don't check for unistd.h.
stdlib.h is universal as well, so there is no need to check for it.
2013-11-18 Tom Tromey <tromey@redhat.com>
* configure: Rebuild.
* configure.ac: Don't check for stdlib.h
* defs.h: Include stdlib.h unconditionally.
2013-11-18 Tom Tromey <tromey@redhat.com>
* configure: Rebuild.
* configure.ac: Don't check for stdlib.h.
* gdbreplay.c: Unconditionally include stdlib.h.
gdb already unconditionally includes stddef.h in many places.
I think there is no reason to check for its existence.
Also, Zack Weinberg's header file survey agrees:
http://hacks.owlfolio.org/header-survey/
This patch removes the configure check and the inclusion guards.
It also removes a redundant inclusion that I noticed in defs.h.
2013-11-18 Tom Tromey <tromey@redhat.com>
* config.in: Rebuild.
* configure: Rebuild.
* configure.ac: Don't check for stddef.h.
* defs.h: Unconditionally include stddef.h. Remove duplicate
inclusion.
This removes gdb_dirent.h and updates the code to use dirent.h
instead. It also removes the now-useless configure checks.
2013-11-18 Tom Tromey <tromey@redhat.com>
* common/common.m4 (GDB_AC_COMMON): Don't use AC_HEADER_DIRENT.
* common/gdb_dirent.h: Remove.
* common/filestuff.c: Use dirent.h.
* common/linux-osdata.c: Use dirent.h.
(NAMELEN): Define.
* config.in: Rebuild.
* configure: Rebuild.
* configure.ac: Don't use AC_HEADER_DIRENT.
* linux-fork.c: Use dirent.h
* linux-nat.c: Use dirent.h.

2013-11-18 Tom Tromey <tromey@redhat.com>
* config.in: Rebuild.
* configure: Rebuild.
* configure.ac: Don't use AC_HEADER_DIRENT.
Now that we are using the gnulib string.h module, we don't need to
check for string.h or strings.h. This removes the last few checks
from the source and from the configure scripts.
2013-11-18 Tom Tromey <tromey@redhat.com>
* configure: Rebuild.
* common/common.m4 (GDB_AC_COMMON): Don't check for string.h or
strings.h.
2013-11-18 Tom Tromey <tromey@redhat.com>
* server.h: Don't check HAVE_STRING_H.
* gdbreplay.c: Don't check HAVE_STRING_H.
* configure: Rebuild.
This removes gdb_string.h. This patch is purely mechanical. I
created it by running the two commands:
git rm common/gdb_string.h
perl -pi -e's/"gdb_string.h"/<string.h>/;' *.[chyl] */*.[chyl]

This imports the gnulib strstr and strerror modules. It doesn't make
any other changes to gdb; I found it simpler to work with the branch
if I made the changes more indepdendent than I had previously.

While adding modules I found that the current approach of listing all
the modules on one line made it harder to experiment -- any conflicts
from git were a pain to resolve.
This patch splits the list of modules so that there is one module per

In the case where the GNAT runtime was built with full debugging info,
several of the exceptions defined there might have a name contain
the word "global". To make this less likely, this patch renames
the exception name, replacing "Global" by "Global_GDB". It still
keeps the exeption name relatively short, while it is unlikely that
the GNAT runtime has an exception whose name explicitly mentions GDB,
and even less likely that it contains "Global_GDB".

If the runtime has full debug info, then the non-standard exceptions

Similar to qsort(), the glibc version of memcpy() also declares its
arguments with __attribute__(__nonnull__(...)). If NULL is passed
anyway, upstream GCC's new pass '-fisolate-erroneous-paths' typically
causes a trap in such cases. I've encountered this with GDB in
chain_candidate() when trying to execute the break.exp test case.

This patch fixes some spurious failures when the inferior is linked
against the shared version of libgnat by default, as appears to be
the case on many GNU/Linux distributions. When that happens, we have
to start the program in order to ensure that the GNAT runtime is
mapped to memory, in order for us to find the standard exceptions
(defined within the runtime). Otherwise, they will not be shown,
as expected, by the debugger.
gdb/testsuite/ChangeLog:
* gdb.ada/info_exc.exp: Start inferior before starting

* gdb.ada/mi_exc_info.exp: Start inferior before starting

This patch fixes PR c++/16117.
gdb has an extension so that users can use expressions like FILE::NAME
to choose a variable of the given name from the given file. The bug
is that this extension takes precedence over ordinary C++ expressions
of the same form. You might think this is merely hypothetical, but
now that C++ headers commonly do not use an extension, it is more
common.
This patch fixes the bug by making two related changes. First, it
changes gdb to prefer the ordinary C++ meaning of a symbol over the
extended meaning. Second, it arranges for single-quoting of the
symbol to indicate a preference for the extension.
Built and regtested on x86-64 Fedora 18.

Consider the following code, compiled at -O2 on ppc-linux:
procedure Increment (Val : in out Float; Msg : String);
The implementation does not really matter in this case). In our example,
this function is being called from a function with Param_1 set to 99.0.
Trying to break inside that function, and running until reaching that
breakpoint yields:
(gdb) b increment
Breakpoint 1 at 0x100014b4: file callee.adb, line 6.
(gdb) run
Starting program: /[...]/foo
Breakpoint 1, callee.increment (val=99.0, val@entry=0.0, msg=...)
at callee.adb:6
6 if Val > 200.0 then
The @entry value for parameter "val" is incorrect, it should be 99.0.
The associated call-site parameter DIE looks like this:
.uleb128 0xc # (DIE (0x115) DW_TAG_GNU_call_site_parameter)
.byte 0x2 # DW_AT_location
.byte 0x90 # DW_OP_regx
.uleb128 0x21
.byte 0x3 # DW_AT_GNU_call_site_value
.byte 0xf5 # DW_OP_GNU_regval_type
.uleb128 0x3f
.uleb128 0x25
The DW_AT_GNU_call_site_value uses a DW_OP_GNU_regval_type
operation, referencing register 0x3f=63, which is $f31,
an 8-byte floating register. In that register, the value is
stored using the usual 8-byte float format:
(gdb) info float
f31 99.0 (raw 0x4058c00000000000)
The current code evaluating DW_OP_GNU_regval_type operations
currently is (dwarf2expr.c:execute_stack_op):
result = (ctx->funcs->read_reg) (ctx->baton, reg);
result_val = value_from_ulongest (address_type, result);
result_val = value_from_contents (type,
value_contents_all (result_val));
What the ctx->funcs->read_reg function does is read the contents
of the register as if it contained an address. The rest of the code
continues that assumption, thinking it's OK to then use that to
create an address/ulongest struct value, which we then re-type
to the type specified by DW_OP_GNU_regval_type.
We're getting 0.0 above because the read_reg implementations
end up treating the contents of the FP register as an integral,
reading only 4 out of the 8 bytes. Being a big-endian target,
we read the high-order ones, which gives us zero.
This patch fixes the problem by introducing a new callback to
read the contents of a register as a given type, and then adjust
the handling of DW_OP_GNU_regval_type to use that new callback.

ELFv2 needs different plt call stubs to ELFv1, register usage differs
too. When I added these to ld I changed register usage in the ELFv1
stubs as well, simplifying the linker code and (perhaps) future
maintenance. All well and good, but this means gdb needs to cope with
more stub variants. This patch also handles skipping over addis/addi
setting up r2 in ELFv2 global entry code. We want breakpoints to be
set past this point to catch calls via the local entry point.
