The gcc.target/i386/avx512fp16-trunchf.c test FAILs on 32-bit Solaris/x86:
FAIL: gcc.target/i386/avx512fp16-trunchf.c scan-assembler-times vcvttsh2si[ \\\\t]+[^{\\n]*(?:%xmm[0-9]|\\\\(%esp\\\\))+, %eax(?:\\n|[ \\\\t]+#) 3
FAIL: gcc.target/i386/avx512fp16-trunchf.c scan-assembler-times vcvttsh2usi[ \\\\t]+[^{\\n]*(?:%xmm[0-9]|\\\\(%esp\\\\))+, %eax(?:\\n|[ \\\\t]+#) 2
This happens because Solaris defaults to -fno-omit-frame-pointer, so it
uses %ebp instead of the expected %esp. As Hongyu Wang suggested in the
PR, this can be fixed by accepting both forms, which this patch does.
Tested on i386-pc-solaris2.11 and x86_64-pc-linux-gnu.
Ok for master?
Rainer

I think this can be put in as an obvious fix.
Thanks for the patch.
