This patch makes sure: - we pass the correct compiler options when building Google benchmarks, - we only import the C++ version of the memory functions. The change in libc/cmake/modules/LLVMLibCTestRules.cmake is here to make sure CMake can generate the right command line in the presence of the CMAKE_CROSSCOMPILING_EMULATOR option. Relevant documentation: https://cmake.org/cmake/help/latest/variable/CMAKE_CROSSCOMPILING_EMULATOR.html https://cmake.org/cmake/help/latest/command/add_custom_command.html#command:add_custom_command " If COMMAND specifies an executable target name (created by the `add_executable()` command), it will automatically be replaced by the location of the executable created at build time if either of the following is true: - The target is not being cross-compiled (i.e. the CMAKE_CROSSCOMPILING variable is not set to true). - New in version 3.6: The target is being cross-compiled and an emulator is provided (i.e. its CROSSCOMPILING_EMULATOR target property is set). In this case, the contents of CROSSCOMPILING_EMULATOR will be prepended to the command before the location of the target executable.
