Author: olista01 Date: Thu Nov 26 09:36:42 2015 New Revision: 254160 URL: http://llvm.org/viewvc/llvm-project?rev=254160&view=rev Log: [AArch64] Add command-line options for ARMv8.2-A
This adds new values for the -march option (armv8.2a and armv8.2-a, which are aliases of each other), and new suffixes for the -march and -mcpu options (+fp16 and +nofp16), to allow targeting the ARMv8.2-A architecture and it's optional half-precision floating-point extension.
