[llvm] [coro][pgo] Remove redundant coroutine test files (PR #89620)
via llvm-commits
llvm-commits at lists.llvm.org
Mon Apr 22 09:15:13 PDT 2024
https://github.com/zmodem created https://github.com/llvm/llvm-project/pull/89620
Each of these is a copy of a test under Transforms/Coroutines/
The PGO functionality is already covered by multiple runlines (pgo and no pgo) in the original files, so the copies add no new coverage, only maintenance problems.

Subject: [PATCH] [coro][pgo] Remove redundant coroutine test files
Each of these is a copy of a test under Transforms/Coroutines/
The PGO functionality is already covered by multiple runlines (PGO and
NOPGO) in the original files, so the copies add no new coverage, only
maintenance problems.
