<p class="MsoNormal">The default CMake options produce a compiler that is capable of targeting all the architectures that were present in the source tree. The list of supported architectures can be reduced using LLVM_TARGETS_TO_BUILD in case you want to save
disk-space, compilation-time, etc.. The default architecture targeted by the resulting compiler is specified by LLVM_TARGET_ARCH and LLVM_DEFAULT_TARGET_TRIPLE.<o:p></o:p></p>

<p class="MsoNormal"><span lang="EN-US">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">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
