Bug ID: 69512
Summary: ICE when using avx with i586
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: chrbr at gcc dot gnu.org
Target Milestone: ---
a reduced case from gcc.target/i386/avx-vcmppd-1.c that fails instead of being
unsupported for testing with -march=i586
attached test compiled with
runs withs -O2 -mavx -march=i586 -m32
ICES with unrecognizable insn
extern double s1[];
extern double s2[];
extern long long e[];
void
avx_test ()
{
int i;
for (i = 0; i < 2; i++)
e[i] = !__builtin_isunordered(s1[i], s2[i]) && s1[i] != s2[i] ? -1 : 0;
}
I suppose that avx is not available for this combination ?, so maybe just
missing an arch incompatible option check ?
