Thanks I’ll test it. Does is also work if the base library pointer is known in the source file prior to the OS call?

If I have move.l execbase, a6 then later jsr -30(a6) same with other base lib etc will it work,
For cheapres.py is the usage is python cheapres.py sourcefile? Any dependencies? Last edited by kamelito; 28 March 2020 at 23:09. |

it will if the base lib is set before -30(a6) is called. I thought I protected the scan when RTS is encountered but it doesn't seem to be the case (working on the script right now so it might be done tonight)
usage is: cheapres.py -i input_file.asm -o output_file.asm. Omitting the output overwrites the input (which can be regenerated at will probably) Dependencies are kept to their minimum (no other python modules than already existing builtins, maybe it would even run on amiga in python 2.4 with minimum adaptations). Maybe time not to divert this thread any further. You can PM me if you have issues, or open a separate thread. Last edited by jotd; 29 March 2020 at 12:50. |

Many thanks, Jotd - very useful.
BTW I think this is relevant to this thread as it is enhancing IRA output. #my2cents |

thanks if someone has issues with the scripts please yell. I have updated them several times since yesterday on my github page. Now cheapres.py is able to insert named offsets from $DFF000 base too as someone suggested.

@PHX
>Maybe you have an editor or viewer which is not set to the standard tab-width of 8? Right thanks notepad++ default is 4 with 8 it is perfect! >Not yet. But I already have that on my ToDo-list for future additions. I mentioned the new directives DATAB, DATAW and DATAL for this purpose. Also on this list: a directive to insert user comments, an option to output mnemonics in lower-case. >No. A global option would be easy, but I guess you would like to see it as a directive for certain regions? I think your directives DATAB DATAW DATAL are the way to go but you could add a char like DATAW_B for word as binary or DATAB_D for decimal, DATAW_H for hex something like that. (Not sure if ascii is needed) >Like library LVOs, this should be done by a post-processor. Jotd has currently >the best options for it!

Also a base offset >$8000 makes no sense. |

BTW I found a very annoying bug in last version of IRA (2.09). I tried to disassemble a binary file (start $80000) like this:
Code:
>ira -a -offset=$80000 -binary heimsp.bin IRA V2.09 (Apr 1 2020) (c)1993-1995 Tim Ruehsen (SiliconSurfer/PHANTASM) (c)2009-2015 Frank Wille (c)2014-2017 Nicolas Bastien Atari's executable files not yet supported. And second IRA HAS DELETED THE FILE! I tried several times, same thing. Version 2.00 works well on that file. I have zoned it if you want to check. |

@jotd how cheapres recognize the different libraries bases? Do you look for specific text like ExecBase, IntuitionBase is their a list? Or is it done differently?

yeah, good question. ExecBase, IntuitionBase, GraphicsBase... basically name of the lib with first letter uppercased. Ex: lowlevel.library => LowlevelBase.
You can manually set them if the program uses a proxy routine to open the libraries (often happens in C programs) |

another strange thing when processing Oscar (ECS) executable.
shitload of messages like this: Watch out: prgcounter(0000d0a0) > nextreloc(000088bc) then P1 Missed bad reloc addr $000088bc! Output is okay, though. |

I cannot remember the details, but probably there was a relocation in the executable's reloc-hunk which the reassembler now skipped in the output, because the code was not detected correctly?
Check offset $88bc. Does it look correct? Is there a label in this location? |
