Describe the bug

I'm trying to analyze ARMv9 binary, compilled with arm-linux-gnueabihf-gcc and getting the following warnings in decompiler:

Unknown calling convention yet parameter storage is locked
[r2ghidra] Matching calling convention arm32 of function sym.imp.abort failed, args may be inaccurate.

I've tried different types of analysis and different types of architecture settings. The best result is achieved with automatic aaa preset

how can I provide Cutter with calling convention type or add support for ARM v9?

Thank you for letting us know!
I moved the issue to r2ghidra-dec repository since it's related to the plugin itself and not to Cutter.=

@ITAYC0HEN Can you point me how can I add support for this binaries?

I was looking for the place in the code (https://github.com/radareorg/r2ghidra-dec/blob/master/src/R2Architecture.cpp#L26) to show you how to fix it, but then accidentally fixed it myself 🙈

r2's arm32 cc maps to __stdcall in sleigh so I added that. It can still happen that you see incorrect function args, especially for imported functions, but that is better tracked in #73.

Nice! So how can I introduce this to my Cutter (Currently stable release)? Should I build from source or do you have some sort of nightly builds stream?

[thestr4ng3r]

The best way is to build all from source, but a new release is scheduled soon too. There are no nightlies provided unfortunately.

Unless you're on windows and then you can download the artifact from AppVeyor
