2006-03-31Implement an item from the readme, folding vcmp/vcmp. instructions withChris Lattner
identical instructions into a single instruction. For example, for: void test(vector float *x, vector float *y, int *P) { int v = vec_any_out(*x, *y); *x = (vector float)vec_cmpb(*x, *y); *P = v; } we now generate: _test: mfspr r2, 256 oris r6, r2, 49152 mtspr 256, r6 lvx v0, 0, r4 lvx v1, 0, r3 vcmpbfp. v0, v1, v0 mfcr r4, 2 stvx v0, 0, r3 rlwinm r3, r4, 27, 31, 31 xori r3, r3, 1 stw r3, 0(r5) mtspr 256, r2 blr instead of: _test: mfspr r2, 256 oris r6, r2, 57344 mtspr 256, r6 lvx v0, 0, r4 lvx v1, 0, r3 vcmpbfp. v2, v1, v0 mfcr r4, 2 *** vcmpbfp v0, v1, v0 rlwinm r4, r4, 27, 31, 31 stvx v0, 0, r3 xori r3, r4, 1 stw r3, 0(r5) mtspr 256, r2 blr Testcase here: CodeGen/PowerPC/vcmp-fold.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27290 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-30Make sure all possible shuffles are matched.Evan Cheng
Use pshufd, pshuhw, and pshulw to shuffle v4f32 if shufps doesn't match. Use shufps to shuffle v4f32 if pshufd, pshuhw, and pshulw don't match. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27259 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-29Change SSE pack operation definitions to fit what the intrinsics expected.Evan Cheng
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27254 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-28When building a VVECTOR_SHUFFLE node from extract_element operations, makeChris Lattner
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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27236 91177308-0d34-0410-b5e6-96231b3b80d8

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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27233 91177308-0d34-0410-b5e6-96231b3b80d8
