 [TySan] Add initial Type Sanitizer support to Clang) (#76260) 2024-12-17T15:13:42+00:00 Florian Hahn flo@fhahn.com 2024-12-17T15:13:42+00:00 c135f6ffe2542bdde5a2a3e1d6515a6fc7031967 This patch introduces the Clang components of type sanitizer: a sanitizer for type-based aliasing violations. It is based on Hal Finkel's https://reviews.llvm.org/D32198. The Clang changes are mostly formulaic, the one specific change being that when the TBAA sanitizer is enabled, TBAA is always generated, even at -O0. It goes together with the corresponding LLVM changes (https://github.com/llvm/llvm-project/pull/76259) and compiler-rt changes (https://github.com/llvm/llvm-project/pull/76261) PR: https://github.com/llvm/llvm-project/pull/76260

 [MTE] Apply alignment / size in AsmPrinter rather than IR (#111918) 2024-12-17T08:47:02+00:00 Florian Mayer fmayer@google.com 2024-12-17T08:47:02+00:00 514580b43898921cc95659de47b383bd2c9b4b12 This makes sure no optimizations are applied that assume the bigger alignment or size, which could be incorrect if we link together with non-instrumented code.
