Bug ID: 80250
Summary: ICE in in final_scan_insn, at final.c:3025 for
__builtin_ia32_vp4dpwssds_mask builtin
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
Target Milestone: ---
Following test-case ICEs:
$ cat ice.i
typedef int a __attribute__ ((__vector_size__ (64)));
__attribute__ ((__vector_size__ (16 * sizeof (float)))) int b ();
#pragma GCC target "avx5124vnniw"
a
c ()
{
long *d;
a e;
a f;
a g;
a h;
a i;
short j = 0;
return __builtin_ia32_vp4dpwssds_mask (h, g, f, e, i, 0, b (), j);
}
$ gcc -O1 -fno-dce ice.i
ice.i: In function ‘c’:
ice.i:15:1: error: could not split insn
}
