...to decide which
vectors should be decomposed.
Thanks,

[LLVMdev] Is there pass to break down <4 x float> to scalars
Hi, LLVM community,
I write some code in hand using LLVM IR. for simplicity, I write them in <4
x float>. now I found some stores for elements are useless.
for example, If I store {0.0, 1.0, 2.0, 3.0} to a <4 x float> %a. maybe
only %a.xy is alive in my program. our target doesn't feature SIMD
instruction, which means we have to lower vector to many scalar
instructions. I found
