[Enhancement] can retrowrite support arm32 architecture?
Platform details Please detail the following:
- Architecture: arm32
- Kernel or userspace: STM32 embeded decives
- Compiler: arm-none-eabi-gcc
- Language (if not obvious from compiler): c
- OS: firmware
I tried to port the retrowrite to the arm32 architecture,but it seems be a lot of questions. the firmware usually has no PIE, is it possible to achieve the arm32 retrowrite?
@wsxk It's still an open problem to distinguish scalars and references for non-PIE binaries... Reassembly is hard, you can refer to this paper
Anyway I'm working on the exactly same target as you. The tool will be released soon (in ~1 month). Contact me if you're interested to this :)

but if I want to make retrowrite appliable in arm32 firmware,I need to distinguish all the scalars and references so that the compiler can reassemble the asm to firmware that runs properly.
@itewqq Could I please ask you about the progress of the compatibility of ARM32? Is there any problem you've met? How did you distinguish scalars and references? Thanks.

I've finished the job like 6 month ago, but my paper was rejected for weird reason so it's still not public lol. Anyway you can DM me and talk about it.
@itewqq If convenient, could you please send me brief summaries of your solutions about this issue? My Email: [email protected], There's a lot of trouble for me to sign up in telegram lol
