PowerPC assembly code in the wild, so it seems, has things like this: bc+ 12, 28, .L9 This is a bit odd because the '+' here becomes part of the BO field, and the BO field is otherwise the first operand. Nevertheless, the ISA specification does clearly say that the +- hint syntax applies to all conditional-branch mnemonics (that test either CTR or a condition register, although not the forms which check both), both basic and extended, so this is supposed to be valid. This introduces some asm-parser-only definitions which take only the upper three bits from the specified BO value, and the lower two bits are implied by the +- suffix (via some associated aliases). Fixes PR23646. llvm-svn: 280571
