Mark drop calls in landing pads `cold` instead of `noinline` Now that deferred inlining has been disabled in LLVM (#92110), this shouldn't cause catastrophic size blowup. I confirmed that the test cases from https://github.com/rust-lang/rust/issues/41696#issuecomment-298696944 still compile quickly (<1s) after this change. ~Although note that I wasn't able to reproduce the original issue using a recent rustc/llvm with deferred inlining enabled, so those tests may no longer be representative. I was also unable to create a modified test case that reproduced the original issue.~ (edit: I reproduced it on CI by accident--the first commit timed out on the LLVM 12 builder, because I forgot to make it conditional on LLVM version) r? `@nagisa` cc `@arielb1` (this effectively reverts #42771 "mark calls in the unwind path as !noinline") cc `@RalfJung` (fixes #46515) edit: also fixes #87055 |
