[LLVMdev] [BUG] Support unqualified btr, bts

[Ramkumar Ramachandra]

Hi,

I happened to notice that linux.git uses plenty of btr and bts
instructions (not btrl, btrw, btsl, btsw).  For examples, see
arch/x86/include/asm/bitops.h.  LLVM barfs on these due to ambiguity,
while GNU as is fine with them.  Surely, there must be architectures
where the w/l variant is unavailable?  LLVM must support those
architectures, no?

Thanks.
