Summary: Previous behaviour of 'R' and 'm' has been preserved for now. They will be improved in subsequent commits. The offset permitted by ZC varies according to the subtarget since it is intended to match the restrictions of the pref, ll, and sc instructions. The restrictions on these instructions are: * For microMIPS: 12-bit signed offset. * For Mips32r6/Mips64r6: 9-bit signed offset. * Otherwise: 16-bit signed offset.
