--- Comment #16 from Marc Poulhi=C3=A8s <poulhies at adacore dot com> ---
Hi!
I'm seeing regressions in pr99744-{1,2,4,5}.c for an i586 target where MMX/=
SSE
are not enabled.

IIUC, your patch inserts "general-regs-only" in x86gprintrin.h if MMX or SS=
E is
enabled and makes the inlining of the calls in theses tests (using
target("general-regs-only")) be compatible with the intrinsics defined in t=
he
header.

In my case, MMX/SSE being both disabled, the calls can't be inlined (mismat=
ch
of target options).

Would that still be correct to change the

     #if defined __MMX__ || defined __SSE__

by

     #if defined __i686__

?=
