2006-10-05add a new SimplifyDemandedVectorElts method, which works similarly toChris Lattner
SimplifyDemandedBits. The idea is that some operations can be simplified if not all of the computed elements are needed. Some targets (like x86) have a large number of intrinsics that operate on a single element, but pass other elts through unmodified. If those other elements are not needed, the intrinsics can be simplified to scalar operations, and insertelement ops can be removed. This turns (f.e.): ushort %Convert_sse(float %f) { %tmp = insertelement <4 x float> undef, float %f, uint 0 ; <<4 x float>> [#uses=1] %tmp10 = insertelement <4 x float> %tmp, float 0.000000e+00, uint 1 ; <<4 x float>> [#uses=1] %tmp11 = insertelement <4 x float> %tmp10, float 0.000000e+00, uint 2 ; <<4 x float>> [#uses=1] %tmp12 = insertelement <4 x float> %tmp11, float 0.000000e+00, uint 3 ; <<4 x float>> [#uses=1] %tmp28 = tail call <4 x float> %llvm.x86.sse.sub.ss( <4 x float> %tmp12, <4 x float> < float 1.000000e+00, float 0.000000e+00, float 0.000000e+00, float 0.000000e+00 > ) ; <<4 x float>> [#uses=1] %tmp37 = tail call <4 x float> %llvm.x86.sse.mul.ss( <4 x float> %tmp28, <4 x float> < float 5.000000e-01, float 0.000000e+00, float 0.000000e+00, float 0.000000e+00 > ) ; <<4 x float>> [#uses=1] %tmp48 = tail call <4 x float> %llvm.x86.sse.min.ss( <4 x float> %tmp37, <4 x float> < float 6.553500e+04, float 0.000000e+00, float 0.000000e+00, float 0.000000e+00 > ) ; <<4 x float>> [#uses=1] %tmp59 = tail call <4 x float> %llvm.x86.sse.max.ss( <4 x float> %tmp48, <4 x float> zeroinitializer ) ; <<4 x float>> [#uses=1] %tmp = tail call int %llvm.x86.sse.cvttss2si( <4 x float> %tmp59 ) ; <int> [#uses=1] %tmp69 = cast int %tmp to ushort ; <ushort> [#uses=1] ret ushort %tmp69 } into: ushort %Convert_sse(float %f) { entry: %tmp28 = sub float %f, 1.000000e+00 ; <float> [#uses=1] %tmp37 = mul float %tmp28, 5.000000e-01 ; <float> [#uses=1] %tmp375 = insertelement <4 x float> undef, float %tmp37, uint 0 ; <<4 x float>> [#uses=1] %tmp48 = tail call <4 x float> %llvm.x86.sse.min.ss( <4 x float> %tmp375, <4 x float> < float 6.553500e+04, float undef, float undef, float undef > ) ; <<4 x float>> [#uses=1] %tmp59 = tail call <4 x float> %llvm.x86.sse.max.ss( <4 x float> %tmp48, <4 x float> < float 0.000000e+00, float undef, float undef, float undef > ) ; <<4 x float>> [#uses=1] %tmp = tail call int %llvm.x86.sse.cvttss2si( <4 x float> %tmp59 ) ; <int> [#uses=1] %tmp69 = cast int %tmp to ushort ; <ushort> [#uses=1] ret ushort %tmp69 } which improves codegen from: _Convert_sse: movss LCPI1_0, %xmm0 movss 4(%esp), %xmm1 subss %xmm0, %xmm1 movss LCPI1_1, %xmm0 mulss %xmm0, %xmm1 movss LCPI1_2, %xmm0 minss %xmm0, %xmm1 xorps %xmm0, %xmm0 maxss %xmm0, %xmm1 cvttss2si %xmm1, %eax andl $65535, %eax ret to: _Convert_sse: movss 4(%esp), %xmm0 subss LCPI1_0, %xmm0 mulss LCPI1_1, %xmm0 movss LCPI1_2, %xmm1 minss %xmm1, %xmm0 xorps %xmm1, %xmm1 maxss %xmm1, %xmm0 cvttss2si %xmm0, %eax andl $65535, %eax ret This is just a first step, it can be extended in many ways.
