correct option to re assemble code resourced by IRA

[kamelito]

Are these the correct options to re assemble a disassembly done via IRA under Windows?

vasm.exe -devpac -m68000 -no-opt -Fhunkexe -kick1hunks file.asm

if you used 68000 to disassemble you don't need to use -m68000. I don't think it's useful in any case, as IRA uses the MC68020 directive if you disassemble with 68020.

I'm using this:

vasmm68k_mot -no-opt -nosym -maxerrors=0 -Fhunkexe -kick1hunks

no-opt is of course required, but nosym is also required, else you get debug symbols and the code is much bigger. -devpac is useless as well.

Correct. IRA always writes the matching CPU directives for the given -M68xxx options into the output, which overwrites vasm command line options.

-devpac may be used instead of -no-opt, as Devpac-compatibility also disables all optimizations.

There may be special cases where you need other options. For example -keepempty, when the original has empty sections which need to be preserved.

Thanks both for the answers.
