[PATCH] D12692: LLVM does not distinguish Cortex-M4 from Cortex-M4F neither Cortex-R5 from R5F

[Alexandros Lamprineas via llvm-commits]

labrinea updated this revision to Diff 34305.
labrinea added a comment.

Previous approach was not very welcome to llvm-dev. Since we want to mimic gcc behaviour I am removing r5f and m4f entries from Target Parser. Updating r5 and m4 FPUs accordingly. A clang patch is required for these changes otherwise there will be regressions.
