After discussions last night, I'm leaning towards going legit with all my pseudo expansions in Mips 16. Some I think I can clearly do by just putting in the proper side effects of implicit registers (T8 the condition code register as used by mips 16). But I'm still left with some pseudos that have jmp .+4 type instructions in them. The original Mips port was to Mips I and Mips I,
