[PATCH] D109243: AMDGPU/GlobalISel: Add build_vector_trunc post-legalizer combine

[Petar Avramovic via Phabricator via llvm-commits]

Petar.Avramovic added a comment.

I don't think this is the best place to perform this combine since there are some regressions in regbank-combiner.
Also I expect that it will be covered by D116441 <https://reviews.llvm.org/D116441> during inst-selection.
