Bug ID: 104790
Summary: [12 Regression] ICE (insn does not satisfy its
constraints) with MVE since
r12-4374-g5efeaa0d29525fa28e189e6278c1b1651fb0d7bf
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: acoplan at gcc dot gnu.org
Target Milestone: ---
The following ICE was reduced from the testsuite:
$ cat t.c
typedef short V __attribute__((vector_size(16)));
V b, c, d;
void f() {
int i;
c = d;
i = 0;
for (; i < 8; ++i)
if (d[i & -i] != b[d[i] - 1])
__builtin_abort();
}
$ gcc/xgcc -B gcc -c t.c -march=armv8.1-m.main+mve -mfloat-abi=hard -O
t.c: In function ‘f’:
t.c:10:1: error: insn does not satisfy its constraints:
