Currently, llvm (backend) doesn't know cortex-r4, even though it is the default target for armv7r. Using "--target=armv7r-arm-none-eabi" provokes 'cortex-r4' is not a recognized processor for this target' by llvm. This patch adds support for cortex-r4 and, very closely related, r4f. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@234486 91177308-0d34-0410-b5e6-96231b3b80d8
