Hi, I wonder if this is a valid flag in either clang/gcc. The flag in question is "-march=aarch64". I verified with latest tip and neither clang nor gcc fail to recognize this flag. This piece of code is in cmake/config-ix.cmake in compiler-rt repo. + elseif("${COMPILER_RT_TEST_TARGET_ARCH}" MATCHES "aarch64") + test_target_arch(aarch64 "-march=aarch64") Anyone have any thoughts or any suggestions ? Currently this is blocking my compiler-rt build for aarch64-linux. --Sumanth G -------------- next part -------------- An HTML attachment was scrubbed... URL...

The point here is, if you are not building for Android. You will hit this patch with cmake configuration -DCOMPILER_RT_TEST_TRIPLE=aarch64-linux-gnu + elseif("${COMPILER_RT_TEST_TARGET_ARCH}" MATCHES "aarch64") + test_target_arch(aarch64 "-march=aarch64") I don't see "-march=aarch64" is a valid flag on either LLVM or GCC. Should we replace this with a flag which is valid for only aarch64 and works for both LLVM and GCC ? If the compiler-rt b...

This is currently a rough area in our build system, but there are two CMake options you probably need to set. (1) -DLLVM_BUILD_EXTERNAL_COMPILER_RT=On —> This option causes the build to use the just-built clang when building compiler-rt (2) -DCOMPILER_RT_DEFAULT_TARGET_ARCH=??? —> This is where you specify which architecture you want to build the compiler-rt archives and libraries for

...ild system successfully configured and built clang/LLVM but failed to configure compiler-rt due to the clang checking in compiler-rt's Cmake system. > I add x86 into LLVM_TARGET_ARCH, and this helps the just-built clang pass the CMake check, but failed in another checking which is invoked by test_target_arch. The test_target_arch is used to setup flags used for building compiler-rt, but it uses try_compile() function, which compiles a simple test code using libraries and invokes linker and linker scripts, flags, etc.. Without compiler-rt, clang will, of course, fails to link programs. However, compiler...
