Ghidra to IRA export: release it or not?

!ZAJC! · 01 August 2024, 10:55

Are there any Ghidra users around interested in seeing an IRA export tool? Poll above.

TLDR:

Ghidra is an open-source reverse engineering framework by NSA (No Such Agency).
ghidra-amiga-ldr is a plugin by Vladimir Kononovich that lets you load an Amiga Hunk Exe, further extended into ghidra-amiga by Bartmann/Abyss
See a video of it in action here [ Show youtube player ] (turn on auto-translated subtitles in Youtube unless you speak Russian)
IRA is a disassembler by phx (Frank Wille) that can take an Amiga executable and create disassembly that can be submitted to vasm and other assemblers and create an identical executable.

I built a Ghidra tool that can export your annotated Ghidra-analyzed Amiga Hunk EXE into an IRA config.

You feed that .cnf file to IRA and get output like this:

Code:

	LEA	s_dos_library_002359c9,A1 ;00030: 43f9000169c9
	JSR	LVO_exec_library_OldOpenLibrary(A6) ;00036: 4eaefe68
	MOVEA.L	(A7)+,A0		;0003a: 205f
	MOVE.L	D0,-(A7)		;0003c: 2f00
	TST.L	172(A5)			;0003e: 4aad00ac
	BEQ.S	is_workbench_process	;00042: 6738
; * Running in CLI
	CLR.W	LineWriteOffset(A4)	;00044: 426c3402
	CLR.W	offs_StartWord0(A4)	;00048: 426c3400
	JSR	parse_stuff		;0004c: 4eb9000002b4
	MOVEA.L	(A7)+,A6		;00052: 2c5f
	MOVEQ	#0,D1			;00054: 7200
	JSR	LVO_dos_library_CurrentDir(A6) ;00056: 4eaeff82

Notice the auto-annotated strings, user-defined comments, labels, auto-generated LVO equates, etc..

Here's a screenshot:

Any interest?

Very cool. This could definitely come in handy. Nicely done.
