WinUAE disasm question
Hello, I can't find the docs that explain the first field in a disasm output:
Code:
-1 00047466 303c 0001 MOVE.W #$0001,D0 -1 0004746A 41f9 0004 6f36 LEA.L $00046f36,A0 -1 00047470 4a28 0039 TST.B (A0,$0039) == $00046f6f [00] -1 00047474 6600 001e BNE.W #$001e == $00047494 (T) -1 00047478 4a39 0004 6f31 TST.B $00046f31 [00] -1 0004747E 6600 0014 BNE.W #$0014 == $00047494 (T) -1 00047482 303c 0000 MOVE.W #$0000,D0 3 0004706A 48e7 fffe MOVEM.L D0-D7/A0-A6,-(A7) -1 000488D8 e350 ROXL.W #$01,D0 -1 000477A6 b03c 0020 CMP.B #$20,D0 I'm trying to figure out why the code jumps all over the place when it hits the MOVEM at 4706A Thanks |

It is CPU interrupt mask. (-1 = mask=0,supervisor mode. 0 = mask=0, user mode)
JIT enabled because output makes no sense? |

Thanks. But JIT is not enabled. I'm using "More compatible" 68000, 24-bit addressing, no MMU and no FPU.

Ok, then make sure at least one break point is enabled. History is only collected if at least one break point is enabled (or when debugger is called). It would slow down emulation noticeably.
for example "f 0" is enough. |

Yes this is history. Which made me scratch my head. I'll keep digging to see why it behaves that way. Thanks.
