Is there a binutils for that ?

[satnatantas]

Yes, there are binutils for both, and also a patch from Simeon Piligrim (Nikon Hacker) to add support for FR80 changes.

Actually, I am stuck at that there is no IDA CPU module for either FR80 or FRV, so I would like to contribute to the project by using existing binutils to add support of these archs to Radare and use it instead. What should I start with?

Any... Link ?

FRV anf FR is inside any recent binutils and GCC release. I compilied binutils for FRV just fine, GCC is a tougher thing though.

[Maijin]

There are tons of examples on how to add architecture from binutils see https://github.com/radare/radare2/wiki/Implementing-a-new-architecture (bottom) or just browse git logs/history

[radare]

new architectures should be added into radare2-extras and packaged in radare2-pm

FR still not present, am I wrong?

[XVilka]

@vitecd not yet, otherwise it would have been closed.

This issue has been moved from radareorg/radare2 to radareorg/ideas as we are trying to clean our backlog and this issue has probably been created a long while ago. This is an effort to help contributors understand what are the actionable items they can work on, prioritize issues better and help users find active/duplicated issues more easily. If this is not an enhancement/improvement/general idea but a bug, feel free to ask for re-transfer to main repo. Thanks for your understanding and contribution with this issue.

It's outrageously ugly, but it works if anyone is interested in FR30/FR60 disassembly:

Binutils cgen is a disaster. And that will increase r2 size a lot. Can you do the PR to r2-extras instead? And make the r2pm package
