2004814a3c Enable unwind tables by default. Assert the default in target-def.h to 
make sure that it sticks.

e8fa8f4db7 Extend ctype classification table to 16bit. Based on patch by 
Takehiko Nozaki, with changes to compile fail when using the old names

ebfcfb962b Fix "ashq" second argument sign extension (the assembler does not treat 
-1 as a 64bit value).
Upstream reported as http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56875
Problemm noted by Jonny Billquist (in lint), hint for solution from mouse.

255fdbee78 Improve the output of gcc when a subprogram gets a signal. When OOMing 
it gets signal 9, which prints "Killed" -- that this is actually
signal 9 and not a generic message is never clear and causes people to
file PRs unnecessarily.

Suggested by followups to PR 44096.

I applied this to gcc 4.5 ages ago, but this copy has been sitting
around in one of my trees for even longer and it may as well get
committed too.

58ca788453 Make GCC define __ARM_PCS and __ARM_PCS_VFP as defined by the ARM C Language 
Extentions (clang already defines them):
__ARM_PCS is defined to 1 if the default procedure calling standard for
the translation unit conforms to the "base PCS" defined in [AAPCS].
__ARM_PCS_VFP is defined to 1 if the default is to pass floating-point
parameters in hardware floating-point registers using the "VFP variant PCS"
defined in [AAPCS].

8743a11216 Apply GCC/35998 from FreeBSD http://svnweb.freebsd.org/changeset/base/245024 
gcc: avoid generating negative values to DW_AT_byte_size.

There is a bug in gcc (GCC/35998) where dwarf reports
sizes of unsigned -1 (0xffffffff).

On NetBSD this generated a faulty CTF entry which then
caused a segfault in ctfmerge. The issue was worked
around in NetBSD's Dtrace but since the issue originated
in gcc, it seems reasonable to fix it here.

Thanks to Christoph Mallon for pointing out a correct fix.

implementation of the same feature.

0bca5478cf Fix ffssi2 again. 
Use a UNSPEC for the internal ffs.
use (match_dup 1) since Z will be set if it is 0 just as if tst:SI was done.
This can let gcc produce better code if you code appropriately.

1ee229bdd2 Remove pattern for arith_adjacentmem in arm.md, thus fixing 
PR toolchain/45576 at a very small run-time cost.

This was suggested by Richard Earnshaw.

A real fix is known to be in gcc 4.5.3 (as in NetBSD-current) and in
gcc-current; don't apply in that tree.

bd081d44b9 Make the MIPS N32/N64 ABIs properly support 128-bit long doubles. With this 
change, we should be fully conformant with the N32 and N64 ABIs.

Note that infinityl_ieee754.c will work with either 64-bit, 80-bit, or
128-bit long doubles.

50eaa87a8f Update pa-netbsd.h to match pa-linux.h where it should. That is, remove 
local definitions of

	ASM_PREFERRED_EH_DATA_FORMAT
	ASM_MAYBE_OUTPUT_ENCODED_ADDR_RTX

and make it obvious we're not using local ASM_OUTPUT_INTERNAL_LABEL

8d2b0eb1d3 make the stdc++ headers usable for clang++. clang wants that __weakref__ 
declarations are "static", gcc-4.1 uses "extern" here.
(gcc-4.2 uses "static" as well, so this looks like a bug in gcc.)
