Subject: Add an extra pow rule to match.pd
From: Richard Sandiford <richard.sandiford@arm.com>
Gcc: private.sent
--text follows this line--
Simplify pow(|x|,y) and pow(-x,y) to pow(x,y) if y is an even integer.
At the moment this duplicates a case in fold_builtin_pow, but an
upcoming patch will move all the fold_builtin_pow rules to match.pd.
I'm doing this one early to fix a regression in builtin-10.c for
soft-float ARM.

I noticed that when testing glibc with a cross compiler I got
UNSUPPORTED: nptl/tst-thread_local1
because the libstdc++-v3 configuration for cross compiling defaulted
to __cxa_thread_atexit_impl not being available. This patch fixes
GLIBCXX_CROSSCONFIG to run the same test (for the case covering
targets with glibc) for __cxa_thread_atexit_impl as for native
compilation, just as it runs most of the other tests done for native
compilation (for these targets, it's not possible to build libstdc++
without already having built libc, so link tests are OK).
Tested with no regressions for cross to arm-none-linux-gnueabi.
* crossconfig.m4 (GLIBCXX_CROSSCONFIG) <*-linux* | *-uclinux* |
*-gnu* | *-kfreebsd*-gnu | *-knetbsd*-gnu | *-cygwin*>: Check for
__cxa_thread_atexit_impl.

As the PR points out, the "simple" reorder algorithm makes bigger code
than the STC algorithm did, for -Os, for x86. I now tested it for many
different targets and it turns out to be worse everywhere.
This simple patch tunes "simple" a bit; this makes it better than STC
almost everywhere. The only exceptions (for the targets where I have
results) are x86 and mn10300. For those targets it may be best to switch
the default algorithm for -Os to STC.
