Good question. It seems to do the right thing in both cases:

I found that if I make modified versions of the intrinsics in arm_neon.h that
are designed more along the lines of the x86_64 SSE intrinsics defined with a
simple pointer dereference, then gcc does the righ

Results for clang and MSVC are similar:
clang trunk:
foo(__simd128_int32_t):
push{r11, lr}
mov r11, sp
sub sp, sp, #24
bfc sp, #0, #4
mov r0, sp

Interesting. Comparing the implementation of _mm_store_si128 to vst1q_s32:
emminitrin.h
extern __inline void __attribute__((__gnu_inline__, __always_inline__,
__artificial__))
_mm_store_si128 (__m128i *__

Are you saying that if the GIMPLE were defined for the intrinsics, then the
optimizer would eliminate them automatically? Or is there more to it?
