URL: https://github.com/llvm/llvm-project/commit/6eda66b0a9f793c65852aa94430ae9bd891bcf63 DIFF: https://github.com/llvm/llvm-project/commit/6eda66b0a9f793c65852aa94430ae9bd891bcf63.diff LOG: PR50294: Fix a performance regression from 2c9dbcd. Per the contract of ReadLateParsedTemplates, we should not be returning the same results multiple times. No functionality change intended, other than to runtime. Thanks to Luboš Luňák for identifying the cause of the regression!
