Function signatures and decorations match gcc/config/i386/smmintrin.h.
Also, copy tests for:
- _mm_cmpeq_epi64
- _mm_mullo_epi32, _mm_mul_epi32
- _mm_packus_epi32
- _mm_cmpgt_epi64 (SSE4.2)
from gcc/testsuite/gcc.target/i386.
2021-08-23 Paul A. Clarke <p...@us.ibm.com>
gcc
* config/rs6000/smmintrin.h (_mm_cmpeq_epi64, _mm_cmpgt_epi64,
_mm_mullo_epi32, _mm_mul_epi32, _mm_packus_epi32): New.
* config/rs6000/nmmintrin.h: Copy from i386, tweak to suit.
gcc/testsuite
* gcc.target/powerpc/pr78102.c: Copy from gcc.target/i386,
adjust dg directives to suit.
* gcc.target/powerpc/sse4_1-packusdw.c: Same.
* gcc.target/powerpc/sse4_1-pcmpeqq.c: Same.
* gcc.target/powerpc/sse4_1-pmuldq.c: Same.
* gcc.target/powerpc/sse4_1-pmulld.c: Same.
* gcc.target/powerpc/sse4_2-pcmpgtq.c: Same.
* gcc.target/powerpc/sse4_2-check.h: Copy from gcc.target/i386,
tweak to suit.

v3:
- Add nmmintrin.h. _mm_cmpgt_epi64 is part of SSE4.2, which is
ostensibly defined in nmmintrin.h. Following the i386 implementation,
however, nmmintrin.h only includes smmintrin.h, and the actual
implementations appear there.
- Add sse4_2-check.h, required by sse4_2-pcmpgtq.c. My testing was
obviously inadequate.
v2:
- Added "extern" to functions to maintain compatible decorations with
like implementations in gcc/config/i386.
- Removed "-Wno-psabi" from tests as unnecessary, per v1 review.
- Noted testing in patch series cover letter.
