2ed3e00940 [windows] Fix accidental change of %u -> %d in SuspendThread warning.
While enhancing the warning printed in when SuspendThread fails,
I accidently changed the format used to print the error code
from %u to %d. This patch reverts it back.

        * windows-nat.c (thread_rec): Revert format used to print
        error code returned by SuspendThread from %d back to %u.

0c3d84be3e windows: Prefix thread ID values with "0x" in debug traces
The windows-nat.c debug traces print the thread ID in base 16,
but give no indication of it. So, in a trace like the following...

    gdb: kernel event for pid=4816 tid=720 code=CREATE_THREAD_DEBUG_EVENT)

... where tid is "720", it's easy to be confused and think that
the thread ID is 720 rather than 0x720.  This patch avoids the
confusion by adding the usual "0x" prefix used for hexadecimal
values.

gdb/ChangeLog:

        * windows-nat.c (windows_continue): Add "0x" prefix for thread
        ID in debug trace.
        (get_windows_debug_event): Likewise, for all debug traces.

80e88e1aa2 windows: Add thread ID in SuspendThread error warning message.
This patch adds the thread ID to a warning printed when a call to
SuspendThread fails. It will help investigate issues, particularly
when correlated with the various debug traces provided by the
windows-nat module.

For the record, the output has been changed from...

    warning: SuspendThread failed. (winerr 6)

... to ...

    warning: SuspendThread (tid=0x720) failed. (winerr 6)

gdb/ChangeLog:

        * window-nat.c (thread_rec): Add thread ID in SuspendThread
        warning message.

b241c8905a sim: bfin: only regen linux-fixed-code.h in maintainer mode
Since many people don't have a Blackfin toolchain available, only try to
regenerate the header file when in maintainer mode.  This file rarely changes,
and when it does, we commit the generated output, so there's almost never a
need to run directly on an end system.

4ec7020176 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.

3aee891821 [GDBserver] Multi-process + multi-arch
This patch makes GDBserver support multi-process + biarch.

Currently, if you're debugging more than one process at once with a
single gdbserver (in extended-remote mode), then all processes must
have the same architecture (e.g., 64-bit vs 32-bit).  Otherwise, you
see this:

... 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.).

88ab56844a gdb/testsuite/gdb.base/long_long.exp: Fix ARM EABI target
glob.

The current glob missed gnueabihf targets. Expand to catch these
cases and fix the test failure on those systems.

42daa7a046 gdb/testsuite/gdb.cp/annota2.exp: Add missing empty line

f4059ef3de 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/testsuite/ChangeLog:

2013-06-07  Will Newton  <will.newton@linaro.org>

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

fe8400b438 gdb/printcmd.c: Fix printing of Thumb minimal symbols.
In build_address_symbolic we call gdbarch_addr_bits_remove for
symbols in the symbol table but not for minimal symbols. This
causes a failure in gdb.cp/virtfunc.exp on ARM, as the address
of the virtual thunk is given an offset of 1 when in Thumb mode.

gdb/ChangeLog:

2013-06-07  Will Newton  <will.newton@linaro.org>

	gdbarch_addr_bits_remove for text minimal symbols.
