[PATCH] D76792: [InlineFunction] Update metadata on loads that are return values

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

For the record, this causes a 0.6-0.8% compile-time regression <http://llvm-compile-time-tracker.com/compare.php?from=0d71782f4e29784873080571f7aebd5bdd163f3f&to=1d0f757904919d19f1cf5dcd307874bceb1e9efb&stat=instructions> on the tramp3d-v4 benchmark (there is also a 0.03% code-size improvement, so at least something is happening there codegen-wise). Can't say whether this is because adding the metadata itself has some cost, or because the presence of the metadata makes further optimization more expensive.
