Bug ID: 80742
Summary: attribute target no- does not work
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: andi-gcc at firstfloor dot org
Target Milestone: ---
Disabling ISAs with attribute target doesn't seem to work on x86_64
e.g.
typedef float __m128 __attribute__ ((vector_size (16)));
__attribute__((target("no-sse2"))) __m128 func (__m128 x, __m128 y)
{
__m128 xmm0 = x, xmm1 = y, xmm2;
xmm0 = __builtin_ia32_xorps (xmm1, xmm1);
return xmm0;
}
does not error out.
