Similar happens with __builtin_ia32_pmovsqw128mem_mask():
$ cat testcase-min0.i
int foo0_u32_0;
__attribute__((__vector_size__(2 * sizeof(long)))) long long foo0_v128s64_0;
char foo0_ret;
void foo0() {
__builtin_ia32_pmovsqw128mem_mask(&foo0_u32_0, foo0_v128s64_0, 15);
foo0_ret = foo0_u32_0;
}
$ x86_64-pc-linux-gnu-gcc -O -mavx512vl testcase-min0.i
during RTL pass: dse1
testcase-min0.i: In function 'foo0':
testcase-min0.i:7:1: internal compiler error: in expand_simple_unop, at
