URL: https://github.com/llvm/llvm-project/commit/1b090db0df47f3ebf6acab0316180267e6b96f43 DIFF: https://github.com/llvm/llvm-project/commit/1b090db0df47f3ebf6acab0316180267e6b96f43.diff LOG: [ARM] Improve diagnostics message when Neon is unsupported Summary: Whenever Neon is not supported, a generic message is printed: error: "NEON support not enabled" Followed by a series of other error messages that are not useful once the first one is printed. This patch gives a more precise message in the case where Neon is unsupported because an invalid float ABI was specified: the soft float ABI. error: "NEON intrinsics not available with the soft-float ABI. Please use -mfloat-abi=softfp or -mfloat-abi=hard" This message is the same one that GCC gives, so it is also making their diagnostics more compatible with each other. Also, by rearranging preprocessor directives, these "unsupported" error messages are now the only ones printed out, which is also GCC's behaviour.
