Summary: ICE in related_vector_mode, at stor-layout.c:537
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3

ICEs when compiling the following testcase, extracted from
gcc/testsuite/gcc.target/i386/sse2-pr94680.c, w/ -maltivec:
typedef long long v2di __attribute__((vector_size(16)));
v2di

{
return __builtin_shuffle ((v2di) { 0, 0 }, x, (v2di) {3, 0});
}
% powerpc-e300c3-linux-gnu-gcc-12.0.0 -maltivec -c z7u847kc.c
during RTL pass: expand
