It brought one warning (with -Asserts, at least),
llvm/lib/Target/Mips/Disassembler/MipsDisassembler.cpp:462:21:
warning: unused function 'DecodeHWRegs64RegisterClass'
[-Wunused-function]
1 warning generated.

> URL: http://llvm.org/viewvc/llvm-project?rev=172284&view=rev
> Log:
> This patch tackles the problem of parsing Mips
> register names in the standalone assembler llvm-mc.
>
> Registers such as $A1 can represent either a 32 or
> 64 bit register based on the instruction using it.
> In addition, based on the abi, $T0 can represent different
> 32 bit registers.
>
>
> The problem is resolved by the Mips specific AsmParser
> td definitions changing to work together. Many cases of
> RegisterClass parameters are now RegisterOperand.
