0a10f22a30 On ARM EABI double precision floating point values are stored in the
endian the CPU is in, i.e. little-endian on most ARM cores.

This allows ARMv4 and ARMv5 boards to boot with the ARM EABI.

003f0fa63f add support to gcc for AES and PCLMUL intrinsics... This addes the
-maes option, but not the -mpclmul option as I ran out of bits in
the 32 bit flags field...  You can -D__PCLMUL__ to get this, but it
won't be compatible w/ clang and modern gcc...

707d0cef66 Pull in r183984 from llvm trunk:
Make PrologEpilogInserter save/restore all callee saved registers in
  functions which call __builtin_unwind_init()

  __builtin_unwind_init() is an undocumented gcc intrinsic which has
  this effect, and is used in libgcc_eh.

  Goes part of the way toward fixing PR8541.

This obsoletes the ugly hack to libgcc's unwind code from r245272, and
should also work for other arches, so revert the hack too.

9636f78ba3 GCC: bring back experimental support for amdfam10/barcelona CPUs.
Initial support for the AMD amdfam10 chipsets has been available in the
gcc43 branch under GPLv2. AMD and some linux distributions (OpenSUSE) did
a backport of the amdfam10 support and made it available.

This is a revised subset of the support initially brought in in r236962
and later reverted. The collateral efects seem to have disappeared but
it is still recommended to set the CPUTYPE with caution.

93c7e89712 Allow the unwind functions int libgcc_s to interact correctly with libthr.
_Unwind_ForcedUnwind in libgcc_s takes as one of it's parameters a stop
function to tell it when to stop unwinding. One of the stop function's
parameters is a _Unwind_Exception_Class. On most architectures this is an
int64_t, however on ARM EABI the gcc developers have made this a char array
with 8 items. While both of these take the same space they are passed into
the stop function differently, an int64_t is passed in in registers r2 and
r3, while the char[8] is passed in as a pointer to the first item in
register r2.

Because libthr expects the value to be an int64_t we would get incorrect
results when it passes a function that take an int64_t but libgcc passes in
a pointer to a char array including crashing.

The fix is to update libgcc_s to make it pass an int64_t to the stop
function and to libstdc++ as it expects _Unwind_Exception_Class to be an
array.

bfd6a1d202 Add an ugly hack to libgcc's unwind code, to make it behave properly at
runtime on amd64, when it is compiled by clang.  Some versions of clang
don't save and restore all callee registers, if a __builtin_eh_return()
intrinsic is used in a function.  This is particularly bad on amd64.

Until the problem gets fixed by upstream, use an asm statement to force
clang to assume the registers in question are clobbered, when invoking
__builtin_eh_return(), so it will emit code to save and restore them.

This should fix the crashes reported on -current with some C++ programs,
particularly those that throw exceptions over multiple function
boundaries.

b76bfc09c3 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.

Upstream gcc has been slow to react to this issue and
the author that submitted the patch is not interested
in licensing the change to us, so I did an independent
workaround for the issue.

d131070105 Don't define CTORS_SECTION_ASM_OP and DTORS_SECTION_ASM_OP on arm when
built with clang. When these are defined the lists are defined similar to:

asm(".section .ctors");
STATIC func_ptr __CTOR_LIST__[1] = { (func_ptr) (-1) };
asm(".section .dtors");
STATIC func_ptr __DTOR_LIST__[1] = { (func_ptr) (-1) };

The problem is clang will move the two arrays out of the .ctors and .dtors
sections causing these sections to contain a single null address. By not
defining these macros we use the version of the code that places the arrays
is their sections by using __attribute__((section(".ctors"))) and similar
for .dtors.

4da573d910 Merging of projects/armv6, part 3
r238211:
Support TARGET_ARCH=armv6 and TARGET_ARCH=armv6eb

This adds a new TARGET_ARCH for building on ARM
processors that support the ARMv6K multiprocessor
extensions.  In particular, these processors have
better support for TLS and mutex operations.

This mostly touches a lot of Makefiles to extend
existing patterns for inferring CPUARCH from ARCH.
It also configures:
 * GCC to default to arm1176jz-s
 * GCC to predefine __FreeBSD_ARCH_armv6__
 * gas to default to ARM_ARCH_V6K
 * uname -p to return 'armv6'
 * make so that MACHINE_ARCH defaults to 'armv6'
It also changes a number of headers to use
the compiler __ARM_ARCH_XXX__ macros to configure
processor-specific support routines.

b375a6d71d Pass --enable-new-dtags to the linker invocation by default. If
desired, one can turn off the generation of post-ELF standard dtags by
overriding it with --disable-new-dtags after the default switch.

Immediate effect of the change is that -rpath path is now stored both
in DT_RPATH and DT_RUNPATH tags, which is the right way to provide
rpath for dynamic linker supporting DT_RUNPATH per specification.

AMD and some linux distributions (OpenSUSE) did a backport of the amdfam10

and while it can improve performance, enabling the CPUTYPE may break some
