3c2ef5414f ia64: makecontext: fix signed warnings
The ia64_rse_is_rnat_slot func expects an unsigned pointer, but we're
passing in a signed pointer.  The signness doesn't matter here, so
convert it to unsigned.

f5ad94e02a arm: Implement armv6 optimized string routines
The strcpy and strchr (and related) functions are four times faster
than the byte-by-byte default versions.

The strlen function is twice as fast for long strings and 50% faster
for short strings over the armv4 version.

adbb8027be Remove PIPE_BUF Linux-specific code
Fixes BZ #12723

The variable pipe buffer size does nothing to the value of PIPE_BUF,
since the number of bytes that are atomically written is still
PIPE_BUF on Linux.

a6f2f43538 arm: Add optimized add_n and sub_n
Written from scratch rather than copied from GMP, due to LGPL 2.1 vs
GPL 3, but tested with the GMP testsuite.

This is 250% faster than the generic code as measured on Cortex-A15,
and the same speed as GMP on the same core, and probably everywhere.

Written from scratch rather than copied from GMP, due to LGPL 2.1 vs
GPL 3, but tested with the GMP testsuite.

This is 50% faster than the generic code as measured on Cortex-A15.
It is 25% slower than the current GMP routine on the same core.

This is 25% faster than the generic code as measured on Cortex-A15,
and the same speed as GMP on the same core.  It's probably slower
than GMP on the A8 and A9 cores though.

92cc8e332b arm: Delete LOADREGS macro
There was only one user.  It's "condition" argument was used
for "ia" rather than an actual condition.  The apcs26 syntax
is almost certainly not needed, given current binutils requirements.

55668624cf arm: Use push/pop mnemonics
For arm this makes no difference--the result is bit-for-bit identical;
for thumb this results in smaller encodings.  Perhaps it ought not and
this is in fact an assembler bug, but I also think it's clearer.

5232b909bf arm: Introduce and use GET_TLS

3ae44082ab arm: Introduce and use NEGOFF series of macros
There are several places in which we access negative offsets from
the thread-pointer, but thumb2 only supports positive offsets in
memory references.

Avoid duplicating the rather large macros in which these references
are embedded by abstracting out the operation.
