[PATCH] D67661: [RISCV] Headers: Add Bitmanip extension Clang header files and rvintrin.h

[Scott Egerton via Phabricator via cfe-commits]

s.egerton updated this revision to Diff 229857.
s.egerton added a comment.

Re-add accidentally reverted update <https://reviews.llvm.org/D67661?id=221334>.

The original message was:

Fixed typos in opcodes. Missing '.'s were added. e.g. adduw -> addu.w

Removed slliu.w functions. There is no single instruction equivalent for when the second argument to the header function is not an immediate. Additionally there is no way of detecting this from C code and throwing a user friendly error message as __builtin_constant_p is not guaranteed to be reliable across inline boundaries at different optimisation levels.

Also rebased on top of upstream commits.
