Using something like this: https://godbolt.org/z/EKEMsaMdW. If I take this patch and remove the ARM::AEK_SIMD from the ARM_ARCH and ARM_CPU_NAME definitions it still seems to do OK. Is there some other reason that AEK_SIMD needs to be added to them? I tried some combinations of -march=..[+[no]fp] and -mfpu=... but they seemed OK and the tests passed. ARM::getFPUFeatures gets used in quite a few places though so something else might be going wrong. https://github.com/llvm/llvm-project/pull/130623 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
