[PATCH] D102090: [CMake][ELF] Add -fno-semantic-interposition and -Bsymbolic-functions

Fri May 7 13:55:35 PDT 2021

phosek added inline comments.

================
Comment at: llvm/cmake/modules/HandleLLVMOptions.cmake:243
+if(${CMAKE_SYSTEM_NAME} MATCHES "DragonFly|FreeBSD|Fuchsia|Linux|NetBSD|OpenBSD")
+  set(CMAKE_SHARED_LINKER_FLAGS "${CMAKE_SHARED_LINKER_FLAGS} -Wl,-Bsymbolic-functions")
+endif()
----------------
I'd really like to avoid modifying `CMAKE_SHARED_LINKER_FLAGS`, modifying these global variables is an antipattern in modern CMake. We should always set these directly on the targets that need them. What's the problem with the approach you used in the first patch?
