Ulrich Weigand a1da2672bd ppc64: Handle short vectors as function return types
Short synthetic vector types (i.e. those defined using GCC's
attribute ((vector_size)) instead of AltiVec vector types)
are returned in r3.  Fix ppc64_sysv_abi_return_value to
correctly handle this.

gdb/ChangeLog:

	* ppc-sysv-tdep.c (ppc64_sysv_abi_return_value_base): Handle short
	synthetic (non-AltiVec) vector types.
	(ppc64_sysv_abi_return_value): Likewise.

Mike Frysinger a348708291 sim: drop -DTRACE from configure
No code uses this anymore and the symbol conflicts with the new TRACE
helper.  Punt it from configure.

Mike Frysinger 5b064994f0 sim: msp430: use new common trace print helpers
Replace the "if (TRACE_xxx_P) trace_generic" form with "TRACE_xxx".
The output is the same, but the code is nicer to read.

Antoine Tremblay 98aa42ee02 Fix MI dprintf-insert not printing on a resolved pending location.
This patch fixes the "Format string required" error when trying to print
a dprintf on a now resolved, pending location when set via the MI interface
even if the format string is entered correctly.

This patch also adds a test case to check that issue called
mi-dprintf-pending.exp.

Mike Frysinger bb11f3ed2b sim: trace: add common macros for logging info

Mike Frysinger db7858e227 sim: cgen: namespace custom trace functions
The cgen code declares some macros/funcs using the trace_xxx prefix, but
the code isn't generic and only works with cgen targets.  This is blocking
the creation of new common trace functions.

Let's blindly add cgen_xxx prefixes to all these symbols.  Some already
use this convention to avoid conflicts, so it makes sense to align them.
In the future we might want to move some to the common trace core, but
one thing at a time.

Walfred Tedeschi 966f0aefa6 Fix broken GDB build after adding Bound table support for i386.
Types used for some variables could not be used for 32 bits, causing a
compilation failure.
This patch adds a cast to force a quite compilation, but at the same
time it bails out in the case that the cast performed is not safe, i.e.
in the case where the debuggee is 64bit and debugger is 32bit.

Documentation was also affected, once a different version of texinfo the
docs could not be build.

When laying out .debug_* sections, we translate the names of compressed

Mike Frysinger 83034798de sim: trace: centralize the system tracing
First we convert the ETRACE_P to STRACE_EVENTS_P.  This means we move from

the sim state works the same as the sim cpu.

Jan Kratochvil 24c05f4605 Fix gdbserver <library-list> and its #FIXED version="1.0"
While reimplementing <library-list/> I found from expat-2.0.1-11.fc15.x86_64:

warning: while parsing target library list (at line 1): Required attribute "version" of <library-list-svr4> not specified

I believe the same bug has to apply for existing FSF gdbserver but I do not
have any <library-list/> platform to test it (I did not try to build MinGW).

features/library-list.dtd:
<!ATTLIST library-list  version CDATA   #FIXED  "1.0">

http://www.xml.com/pub/a/98/10/guide0.html?page=3 says:

	In this case, the attribute is not required, but if it occurs, it must
	have the specified value.

Which would suggest gdbserver is right but solib-target.c is wrong.  One could
also make gdbserver explicit for the version (if those 14 bytes are not of
a concern).

Gary Benson 12e2a5fdcc Comment and whitespace changes
Comments on the various implementations of target fileio functions
duplicate information documented in target.h.  This commit replaces
the duplicated documentation with breadcrumbs, and inserts blank

necessary.

Jon Turney 5d9c55d355 windows-nat: Also ignore ERROR_INVALID_HANDLE from SuspendThread()
Discussed somewhat in the thread at
https://cygwin.com/ml/gdb-patches/2013-06/msg00680.html

This is pretty straightforward to demonstrate on Cygwin currently:

$ cat main.c

int main()
{
  return 0;
}

$ gcc -g -O0 main.c -o main

$ ./gdb ./main
[...]
(gdb) r
Starting program: /wip/binutils-gdb/build.x86_64/gdb/main
warning: SuspendThread (tid=0x1cf0) failed. (winerr 6)
[Inferior 1 (process 976) exited normally]

with this patch applied:

$ ./gdb ./main
[...]
(gdb) r
Starting program: /wip/binutils-gdb/build.x86_64/gdb/main
[Inferior 1 (process 4852) exited normally]

gdb/ChangeLog:

2015-06-03  Jon Turney  <jon.turney@dronecode.org.uk>

	* windows-nat.c (thread_rec): Also ignore ERROR_INVALID_HANDLE
	from SuspendThread().
