[clang] [compiler-rt] PREVIEW: Introduce realtime sanitizer backend (PR #91529)
Chris Apple via cfe-commits
cfe-commits at lists.llvm.org
Wed May 8 13:18:51 PDT 2024
https://github.com/cjappl created https://github.com/llvm/llvm-project/pull/91529
This introduces a nice self contained piece
All interceptors
All infrastructure "boilerplate" cmake
All unit tests (no lit tests)
Minimal meddling in clang, just to get the tests running
Unit tests for this RUN which I think is what makes this a great chunk.
