Michael Gottesman b9205da3c6 [InstCombine] Teach InstCombine how to handle an obfuscated splat. ... An obfuscated splat is where the frontend poorly generates code for a splat using several different shuffles to create the splat, i.e., %A = load <4 x float>* %in_ptr, align 16 %B = shufflevector <4 x float> %A, <4 x float> undef, <4 x i32> <i32 0, i32 0, i32 undef, i32 undef> %C = shufflevector <4 x float> %B, <4 x float> %A, <4 x i32> <i32 0, i32 1, i32 4, i32 undef> %D = shufflevector <4 x float> %C, <4 x float> %A, <4 x i32> <i32 0, i32 1, i32 2, i32 4> llvm-svn: 166061		2012-10-16 21:29:38 +00:00
