--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I've tried to reproduce it with
typedef __simd128_int32_t int32x4_t;
void
foo (int32x4_t c)
{
int32x4_t b = __builtin_neon_vdup_nv4si (3);
register int32x4_t a __asm ("d16");
asm volatile ("" : "=w" (a));
a = a >> b;
a |= c;
asm volatile ("" : : "w" (a));
}
but it doesn't, for some reason the ICE needs a REG_EQUAL attribute on the
right shift into which we propagate the constant and LRA picks the constant
from there, but haven't managed to force that.
