* [Bug testsuite/44159] New: CPU options cause testsuite failures

On x86_64-w64-mingw32 targets, during tests such as avx-vaddpd-1.c, the
testsuite fails. This seems to be due to the fact that the test function is
inlined into main. Due to this inlining, some of the the xmm registers are
saved and restored. However, because the -mavx flag is passed, the register
saves are performed using instructions not available on the CPU. In other
words, the register save/restore is performed before the __cpuid function is
called to determine whether the test is supported on the machine that is
running the test.
This is hit-and-miss and is problematic on any tests that require unsupported
registry saves on this target type.

------- Comment #1 from dougsemler at gmail dot com 2010-05-16 14:23 -------
Created an attachment (id=20672)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=20672&action=view)
Assembly that shows unsupported registry saves
This assembly is made from:
/opt/build/x86_64-pc-linux/x86_64-w64-mingw32/gcc/gcc/xgcc
-B/opt/build/x86_64-pc-linux/x86_64-w64-mingw32/gcc/gcc/
/opt/src/repos/gcc.git/gcc/testsuite/gcc.target/i386/avx-vaddpd-1.c -O2 -mavx
-lm -o ./avx-vaddpd-1.exe
during a test suite run. As can be seen, the vmovdqa instruction is used to
save the registers xmm6,7, and 8 prior to the __cpuid test...which is not
available on my core2 duo.
