--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The first arg doesn't have to be constant:
typedef int __attribute__ ((__vector_size__ (16))) V;
typedef long __attribute__ ((__vector_size__ (16))) W;
void
foo (W *x)
{
*x = __builtin_shuffle (*x, (W){}, (W)(V){0, 0, -15, 0});
}
__builtin_shuffle is documented:
"The elements of MASK are considered modulo N in the single-operand case and
modulo 2*N in the two-operand case."
and as there are two operands, that means modulo 4, so the result should be
the same as
*x = __builtin_shuffle (*x, (W){}, (W){0, 1});
I think and thus a nop.

--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I guess there are two issues, one is a backend issue that vec_shr_optab
expander doesn't handle shift amount 0 correctly, and another in the
middle-end, that it shouldn't be dumb and for shift_amt == const0_rtx should
just return v0.

Shortcut identity VEC_PERM expansion [PR94710]
This PR is about the rs6000 backend emitting wrong assembly
for whole vector shift by 0, and while I think it is desirable
to fix the backend, I don't see a point why the expander should
try to emit that, whole vector shift by 0 is identity, we can just
return the operand.

out to be caused by a failure to make of the higher bits in an index
endian conversion.
