[Michael Liao via Phabricator via llvm-commits]

hliao added a comment.

Add TTI hooks to double-check that address space casting is no-op.

NOTE: This change depends on
- https://reviews.llvm.org/D82025 (exposing `isNoopAddrSpaceCast` from TLI into TTI) to be compiled.
- https://reviews.llvm.org/D81943 (enhance SROA to handle no-op address space casting) to pass all testing.
