So the debugger can show them during stepping. The fmt_* functions now take a PPCDisasmContext instead of just the ctx->instr_str so that they can alter the context. Some fmt_* functions have an alternate (e.g. fmt_twoop_in for fmt_twoop) to indicate a difference in input/output registers. The mtsrin and mfsrin instructions use a register to indicate which sr register to use. The string instructions may affect multiple registers but only the first is included in the list. Removed some extra blank lines. Fixes: lscbx: Add r0 check. mftb: Do simplified if the spr is illegal. Maybe should do illegal opcode instead?
