URL: https://github.com/llvm/llvm-project/commit/fd57946cc4f11fe4610d3544b61041f306823f81 DIFF: https://github.com/llvm/llvm-project/commit/fd57946cc4f11fe4610d3544b61041f306823f81.diff LOG: [NFC][clang] Update ubsan-trap-merge.c test to show absence of nomerge in non-trap mode (#119280) This shows that ubsan handlers do not have nomerge attributes in non-trap mode, even if -ubsan-unique-trap is enabled. 0d15d46362bd6ab5a9a2165805adaab13a7689f4 attaches nomerge but only for trap mode. --------- Co-authored-by: Vitaly Buka <vitalyb...@gmail.com> Added: Modified:
