URL: https://github.com/llvm/llvm-project/commit/4aa1cadf3c67c61b394051630896f06f35b562ca DIFF: https://github.com/llvm/llvm-project/commit/4aa1cadf3c67c61b394051630896f06f35b562ca.diff LOG: [Driver] Disable -fsanitize=function for ppc64be after D148573 ELFObjectWriter.cpp may report ``` error: Cannot represent a difference across sections ``` on some ppc64be configurations, likely related to some interaction between the obsoleted ELFv1 and MC. Unfortunately I cannot reproduce this locally with --target=powerpc64-linux-gnu.
