In the common case where we are shuffling a vector, emit an
...
llvm vector shuffle instead of a bunch of insert/extract operations.
For: vec4 = vec4.yyyy; // splat
Emit:
%tmp1 = shufflevector <4 x float> %tmp, <4 x float> undef, <4 x i32> < i32 1, i32 1, i32 1, i32 1 >
instead of:
%tmp1 = extractelement <4 x float> %tmp, i32 1
%tmp2 = insertelement <4 x float> undef, float %tmp1, i32 0
%tmp3 = extractelement <4 x float> %tmp, i32 1
%tmp4 = insertelement <4 x float> %tmp2, float %tmp3, i32 1
%tmp5 = extractelement <4 x float> %tmp, i32 1
%tmp6 = insertelement <4 x float> %tmp4, float %tmp5, i32 2
%tmp7 = extractelement <4 x float> %tmp, i32 1
%tmp8 = insertelement <4 x float> %tmp6, float %tmp7, i32 3
