Evan Cheng 7e2ff11a42 Make sure all possible shuffles are matched. 
Use pshufd, pshuhw, and pshulw to shuffle v4f32 if shufps doesn't match.

Evan Cheng c5cf9bba05 Change SSE pack operation definitions to fit what the intrinsics expected. 
For example, packsswb actually creates a v16i8 from a pair of v8i16. But since
the intrinsic specification forces the output type to match the operands.

Evan Cheng 38b34296d0 Added aliases to scalar SSE instructions, e.g. addss, to match x86 intrinsics. 
The source operands type are v4sf with upper bits passes through.
Added matching code for these.

Evan Cheng c2c8b58cf6 Don't sort the names before outputing the intrinsic name table. It causes a 
mismatch against the enum table.
This is a part of Sabre's master plan to drive me nuts with subtle bugs that
happens to only affect x86 be. :-)

Chris Lattner 20e619fba3 When building a VVECTOR_SHUFFLE node from extract_element operations, make 
sure to build it as SHUFFLE(X, undef, mask), not SHUFFLE(X, X, mask).

The later is not canonical form, and prevents the PPC splat pattern from
matching.  For a particular splat, we go from generating this:

	li r10, lo16(LCPI1_0)
	lis r11, ha16(LCPI1_0)
	lvx v3, r11, r10
	vperm v3, v2, v2, v3

to generating:

	vspltw v3, v2, 3

Chris Lattner 112cee1182 new testcase 
llvm-svn: 27234
 2006-03-28 20:32:12 +00:00
Chris Lattner c9992548fc Turn a series of extract_element's feeding a build_vector into a 
vector_shuffle node.  For this:

void test(__m128 *res, __m128 *A, __m128 *B) {
  *res = _mm_unpacklo_ps(*A, *B);
}

we now produce this code:

_test:
        movl 8(%esp), %eax
        movaps (%eax), %xmm0
        movl 12(%esp), %eax
        unpcklps (%eax), %xmm0
        movl 4(%esp), %eax
        movaps %xmm0, (%eax)
        ret

instead of this:

_test:
        subl $76, %esp
        movl 88(%esp), %eax
        movaps (%eax), %xmm0
        movaps %xmm0, (%esp)
        movaps %xmm0, 32(%esp)
        movss 4(%esp), %xmm0
        movss 32(%esp), %xmm1
        unpcklps %xmm0, %xmm1
        movl 84(%esp), %eax
        movaps (%eax), %xmm0
        movaps %xmm0, 16(%esp)
        movaps %xmm0, 48(%esp)
        movss 20(%esp), %xmm0
        movss 48(%esp), %xmm2
        unpcklps %xmm0, %xmm2
        unpcklps %xmm1, %xmm2
        movl 80(%esp), %eax
        movaps %xmm2, (%eax)
        addl $76, %esp
        ret

GCC produces this (with -fomit-frame-pointer):

_test:
        subl    $12, %esp
        movl    20(%esp), %eax
        movaps  (%eax), %xmm0
        movl    24(%esp), %eax
        unpcklps        (%eax), %xmm0
        movl    16(%esp), %eax
        movaps  %xmm0, (%eax)
        addl    $12, %esp
        ret
