86ee76a086 hppa: Update libm-test-ulps
Update libm-test-ulps for hppa. There are a few entries
with 4 or 5 ulps, but these appear to be expected. A more
thorough review will be required if hppa switches long-double
to a different type.

b7f7d28b61 hppa: Fix _FPU_GETCW and _FPU_SETCW.
The following patch fixes both _FPU_GETCW and
_FPU_SETCW for hppa. The initial implementation was
flawed and not well tested. We failed to set cw,
and passed in the value of a register to fldd.
This patch fixes both of those errors and allows
the libm tests to pass without failure.

4fdd5ec125 ia64: fix set-but-unused warnings with syscalls
These macros often set up a variable that later macros sometimes do
not use.  Add unused attribute to avoid that.

Similarly, the ia64 code tends to check the err field rather than
the val (which is opposite of most arches) leading to the same
kind of warning.  Replace this with a dummy reference.

a186dc916c ia64: fix strict aliasing warnings with libm error
The current code declares double constants by using a char buffer and
then casting the pointer to a different type.  This makes the aliasing
logic unhappy.  Change it to use a union instead to avoid that.

c5abd7ce01 ia64: fix strict aliasing warnings with func descriptors
Function pointers on ia64 are like parisc -- they're plabels.  While
the parisc port enjoys a gcc builtin for extracting the address here,
ia64 has no such luck.

Casting & dereferencing in one go triggers a strict aliasing warning.
Use a union to fix that.

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.

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.
