search for: llvm_target_arch

I've been working on getting the LLVM OpenMP library to build smoothly alongside llvm/clang using CMake, but one problem I'm having is determining exactly which CMake option designates the architecture the compiler will compile. I see LLVM_TARGET_ARCH, LLVM_TARGETS_TO_BUILD, LLVM_DEFAULT_TARGET_TRIPLE, etc. I thought I should just ask which one designates the architecture the compiler will build, but I wouldn't mind an explanation for all of them :) And yes, I've looked at http://llvm.org/docs/CMake.html, but am still confused. Any he...

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

...work, but -DCOMPILER_RT_DEFAULT_TARGET_TRIPLE works. > While using there two additional options, I still got errors. The build 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 invoke...

That seems to work (see below). $ cd
