[PATCH] D12344: ARM: Error out if float-ab=hard and abi=apcs-gnu on macho platforms

[Akira Hatanaka via cfe-commits]

ahatanak added a comment.

float-abi=hard has no effect on the backend code-generation if the ABI is APCS, meaning GPRs will be used to pass floating point arguments. This patch makes changes to the driver so that the error is detected in the front-end rather than silently ignoring the option in the backend.
