[llvm-dev] KNL Vectorization with larger vector width

[hameeza ahmed via llvm-dev]

Hello,

If we pass march=knl, the llvm vectorizer (O3) generates max 16xi32 vector
width instruction and 8xi32 or 4xi32 in recursive manner.

I am working on a target with larger vector widths like 32,64...
Now how to enable the vectorizer (O3) to automatically generate larger
vector size instructions recursively by specifying the new target. Which
files have the code for this?


Please help

Thank You
Regards
