A quick google for MIPS and dror32 seems to point to NEC and
SandCraft.

e.g. see the very brief descriptions of dror, dror32, and drorv on

http://www.sandcraft.com/products/gnu/17_assembler.html

which seems to indicate that they're the direct analogues of dsll et
al.


So, if there's going to be a 64-bit ror/rol, i really do think they
should be dro[rl] (and it might be good to have assembler macros that
DTRT w/ the rest of the variants of the dro? and ro? insns 8-).
