I'm guessing this is what you are suggesting: In getAArch64TargetCPU, if it finds out the cpu name passed via -mtune or -mcpu is "native", 1. Call llvm::sys::getHostCPUName to get the host CPU name. 2. Check the host CPU name to see if it is a valid AArch64 CPU. A CPU is valid if it is one of these CPUs: cyclone, cortex-a53, cortex-a57, cortex-a72, or generic (this is the set of CPUs that are valid in DecodeAArch64Mcpu). 3. If the host CPU is valid, return the CPU name. Otherwise, return "native". http://reviews.llvm.org/D14471 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
