[PATCH] [mips] Expansion of ROL and ROR instructions

[Daniel Sanders]

I believe it's closely related. On MIPS32r2 and later, ror/rol are aliases for rotr and rorv/rolv are aliases for rotrv/rotlv. Prior to MIPS32r2, they are macros that expand to equivalent code as per your patch.

Either way, you need to account for the case when the rotation immediate is zero.
