There was a problem hiding this comment.
Note: we usually try to make the attributes be first class in the operation, this is fine for alignment because it's already the case in many tests.

We have some easy missing features here for next PRs, nice! Let me create an issue to track.

…VM (llvm#810) As title. Add setAlignmentAttr for GlobalOps created from AST. LLVM Lowering should have LLVM GlobalOp's alignment attribute inherited from CIR::GlobalOp. This PR is definitely needed to fix issue llvm#801 (comment), but the issue doesn't have alignment and comdat attribute for CIR Ops to begin with, so I'll keep investigating and fix CIR problem in another PR.
