This reverts commitd763c6e5e2. Adds the patch by @hans from https://github.com/llvm/llvm-project/issues/62719 This patch fixes the Windows build.d763c6e5e2reverted the reviews D144509 [CMake] Bumps minimum version to 3.20.0. This partly undoes D137724. This change has been discussed on discourse https://discourse.llvm.org/t/rfc-upgrading-llvms-minimum-required-cmake-version/66193 Note this does not remove work-arounds for older CMake versions, that will be done in followup patches. D150532 [OpenMP] Compile assembly files as ASM, not C Since CMake 3.20, CMake explicitly passes "-x c" (or equivalent) when compiling a file which has been set as having the language C. This behaviour change only takes place if "cmake_minimum_required" is set to 3.20 or newer, or if the policy CMP0119 is set to new. Attempting to compile assembly files with "-x c" fails, however this is workarounded in many cases, as OpenMP overrides this with "-x assembler-with-cpp", however this is only added for non-Windows targets. Thus, after increasing cmake_minimum_required to 3.20, this breaks compiling the GNU assembly for Windows targets; the GNU assembly is used for ARM and AArch64 Windows targets when building with Clang. This patch unbreaks that. D150688 [cmake] Set CMP0091 to fix Windows builds after the cmake_minimum_required bump The build uses other mechanism to select the runtime.
