[PATCH] D71553: [RISCV] Add Clang frontend support for Bitmanip extension

2020-01-14 Thread Sam Elliott via Phabricator via cfe-commits 
lenary added a comment.

@s.egerton Please can you revert rG57cf6ee9c84434161088c39a6f8dd2aae14eb12d 
 - this 
patch has open dependencies, including on the LLVM support for RISC-V B 
extension. It would be confusing to users if clang 10.0 contained frontend 
support for the B extension, but LLVM 10.0 did not contain backend support for 
it.

Sorry for the confusion around marking this as approved.

Thanks Scott, it should be relatively easy to add tests for this in 
'clang/test/Preprocessor/riscv-target-features.c' if you could.
