[PATCH] D149842: Scalarizer: limit scalarization for small element types

[Piotr Sobczak via Phabricator via llvm-commits]

piotr added a comment.

Having looked at some real-world graphics content on AMDGPU (with ScalarizeMinBits = 32), I can confirm the usefulness of this patch. I can see more packed instructions generated (for example v_pk_add_f16, v_pk_mul_f16, v_pk_fma_f16).
