We wrote a test case that tries every single 32bit opcode on the hardware

[Darwin] Fix cleanup leak in machoread.c:macho_symfile_read
This patch fixes a cleanup leak in macho_symfile_read (symbol_table):
symbol_table = (asymbol **) xmalloc (storage_needed);
make_cleanup (xfree, symbol_table);
Unfortunately, fixing the leak alone triggers a crash which occurs
while loading the symbols from an executable:
% gdb
(gdb) file g_exe
[SIGSEGV]
The crash is caused by the fact that performing the cleanup
right after the call to macho_symtab_read, as currently done,
is too early.
Indeed, references to this symbol_table get saved in the oso_vector
global during the call to macho_symtab_read via calls to
macho_register_oso, and those references then get accessed
later on, when processing all the OSOs that got pushed (see
call to macho_symfile_read_all_oso).
This patch prevents this by using one single cleanup queue for
the entire function, rather than having additional separate
cleanup queues (Eg: for the handling of the minimal symbols),
thus preventing the premature free'ing of the minimal_symbols
array.
Secondly, this patch takes this opportunity for avoiding the use
of the oso_vector global, thus making it simpler to track its
lifetime.
gdb/ChangeLog:
* machoread.c (oso_vector): Delete this global.
(macho_register_oso): Add new parameter "oso_vector_ptr".
Use it instead of the "oso_vector" global.
(macho_symtab_read, macho_symfile_read_all_oso): Likewise.
(macho_symfile_read): Use a local oso_vector, to be free'ed
at the end of this function, in place of the old "oso_vector"
global. Update various function calls accordingly. Use one
single cleanup chain for the entire function.

do not use dwarf2_per_objfile in dwarf2_per_objfile_free.
This patch fixes a case of multiple calls freeing the same data
while free-ing objfiles that have child objfiles (separate debug
info, as is the case on Darwin targets).
Following the code, free_objfile_separate_debug iterates over
all child objfiles of the parent objfile, calling free_objfile:
for (child = objfile->separate_debug_objfile; child;)
{
struct objfile *next_child = child->separate_debug_objfile_link;
free_objfile (child);
child = next_child;
}
This causes, among other things, the free'ing of the child objfile's
private data:
/* Discard any data modules have associated with the objfile. The function
still may reference objfile->obfd. */
objfile_free_data (objfile);
This indirectly calls(back) dwarf2_per_objfile_free, which tries
to free the dwarf2read-specific data by using the dwarf2_per_objfile
global, eg:
for (ix = 0; ix < dwarf2_per_objfile->n_comp_units; ++ix)
Even if we were lucky enough the first time around that this global
actually corresponds to the objfile being destroyed, the global
will still have the same value at the second iteration, and thus
become dangling. Indeed, after dwarf2_per_objfile_free returns
eventually back to free_objfile, free_objfile then deallocates
its objfile_obstack, where the dwarf2_per_objfile is allocated.
Ironically, there should be no need to access that global at all,
here, since the data is passed as an argument of the callback.
And it looks like the dwo/dwp/[...]-handling code is in fact already
using that argument, rather than the global.
This patch thus fixes the problem by doing the same, replacing
all references to DWARF2_PER_OBJFILE by uses of DATA instead.

* dwarf2read.c (dwarf2_per_objfile): Replace uses of
DWARF2_PER_OBJFILE by uses of DATA instead.

Fix PR cli/15603
This fixes PR cli/15603.
The bug here is that when a software watchpoint is being used, gdb
will stop responding to C-c. This is a regression caused by the
"catch signal" patch.
The problem is that software watchpoints always end up on the bpstat
list. However, this makes bpstat_explains_signal return
BPSTAT_SIGNAL_HIDE, causing infrun to think that the signal is not a
"random signal".
The fix is to change bpstat_explains_signal to handle this better. I
chose to do it in a "clean API" way, by passing the signal value to
bpstat_explains_signal and then adding an explains_signal method for
watchpoints, which handles the specifics.

Fix PR symtab/15391
PR symtab/15391 is a failure with the DW_OP_GNU_implicit_pointer
feature.
I tracked it down to a logic error in read_pieced_value. The code
truncates this_size_bits according to the type size and offset too
early -- it should do it after taking bits_to_skip into account.
This patch fixes the bug.
While testing this, I also tripped across a latent bug because
indirect_pieced_value does not sign-extend where needed. This patch
fixes this bug as well.
Finally, Pedro pointed out that a previous version implemented sign
extension incorrectly. This version introduces a new gdb_sign_extend
function for this. A couple of notes on this function:
* It has the gdb_ prefix to avoid clashes with various libraries that
felt free to avoid proper namespacing. There is a "sign_extend"
function in a Tile GX header, in an SOM-related BFD header (and in
sh64-tdep.c and as a macro in arm-wince-tdep.c, but those are
ours...)
* I looked at all the sign extensions in gdb and didn't see ones that
I felt comfortable converting to use this function; in large part
because I don't have a good way to test the conversion.
Built and regtested on x86-64 Fedora 18. New test cases included;
this required a minor addition to the DWARF assembler. Note that the
DWARF CU made by implptrpiece.exp uses a funny pointer size in order
to show the sign-extension bug on all platforms.

Remove superfluous semicolons from testsuite throughout.
A few months ago semicolons after "return" were removed throughout the
testsuite. However, as I pointed out in review, they're unnecessary
not just after "return", but pretty much after any tcl command. ';'
is the command separator, and you only need it if there's another
command on the same line afterwards.
This patch was written by running:
$ find . -name "*.exp" | xargs grep -l ";\s*$" | xargs sed -i 's/\([^#][^\s*;]*\)\s*;\s*$/\1/'
and then undoing changes to comments, and lib/future.exp.
Tested on x86_64 Fedora 17.

... etc, etc ...
Even though the process was running a 32-bit program, GDBserver sent
back to GDB a register set in 64-bit layout.
A patch (http://sourceware.org/ml/gdb-patches/2012-11/msg00228.html) a
while ago made GDB track a target_gdbarch per inferior, and as
consequence, fetch a target description per-inferior. This patch is
the GDBserver counterpart, that makes GDBserver keep track of each
process'es XML target description and register layout. So in the
example above, GDBserver will send the correct register set in 32-bit
layout to GDB.
A new "struct target_desc" object (tdesc for short) is added, that
holds the target description and register layout information about
each process. Each `struct process_info' holds a pointer to a target
description. The regcache also gains a pointer to a target
description, mainly for convenience, and parallel with GDB (and
possible future support for programs that flip processor modes).
The low target's arch_setup routines are responsible for setting the
process'es correct tdesc. This isn't that much different to how
things were done before, except that instead of detecting the inferior
process'es architecture and calling the corresponding
init_registers_FOO routine, which would change the regcache layout
globals and recreate the threads' regcaches, the regcache.c globals
are gone, and the init_registers_$BAR routines now each initialize a
separate global struct target_desc object (one for each arch variant
GDBserver supports), and so all the init_registers_$BAR routines that
are built into GDBserver are called early at GDBserver startup time
(similarly to how GDB handles its built-in target descriptions), and
then the arch_setup routine is responsible for making
process_info->tdesc point to one of these target description globals.
The regcache module is all parameterized to get the regcache's layout
from the tdesc object instead of the old register_bytes, etc. globals.
The threads' regcaches are now created lazily. The old scheme where
we created each of them when we added a new thread doesn't work
anymore, because we add the main thread/lwp before we see it stop for
the first time, and it is only when we see the thread stop for the
first time that we have a chance of determining the inferior's
architecture (through the_low_target.arch_setup). Therefore when we
add the main thread we don't know which architecture/tdesc its
regcache should have.
This patch makes the gdb.multi/multi-arch.exp test now pass against
(extended-remote) GDBserver. It currently fails, without this patch.
The IPA also uses the regcache, so it gains a new global struct
target_desc pointer, which points at the description of the process it
is loaded in.
Re. the linux-low.c & friends changes. Since the register map
etc. may differ between processes (64-bit vs 32-bit) etc., the
linux_target_ops num_regs, regmap and regset_bitmap data fields are no
longer sufficient. A new method is added in their place that returns
a pointer to a new struct that includes all info linux-low.c needs to
access registers of the current inferior.
The patch/discussion that originally introduced
linux-low.c:disabled_regsets mentions that the disabled_regsets set
may be different per mode (in a biarch setup), and indeed that is
cleared whenever we start a new (first) inferior, so that global is
moved as well behind the new `struct regs_info'.
On the x86 side:
I simply replaced the i387-fp.c:num_xmm_registers global with a check
for 64-bit or 32-bit process, which is equivalent to how the global
was set. This avoided coming up with some more general mechanism that
would work for all targets that use this module (GNU/Linux, Windows,
etc.).

gdb/testsuite/gdb.cp/annota2.exp: Add missing empty line
in output.
There should be an empty line between "post-prompt" and "starting".
This fixes a testsuite failure on ARM.

gdb/testsuite/gdb.cp: Fix tests for ARM C++ ABI.
The ARM C++ ABI defines constructors and destructors to return
pointers to this. The C++ tests that check the types of constructors
and destructors expect a return type of void. Conditionalize these
tests so they pass on ARM.

* gdb.cp/anon-struct.exp: Conditionalize constructor and
destructor prototypes for ARM ABI.
* gdb.cp/m-static.exp: Likewise.
