GSoC 2020: SLEIGH Disassembler Backend


Hello all, I’m Jiaxiang Zhou from China. I was lucky to be selected as a participant of Radare2 project this year. My main work was to integrate SLEIGH as a disassembly backend into Radare2. r2ghidra-dec was my main working repository, aiming to delivering Ghidra’s decompiler to Radare2. It could be renamed as r2ghidra since it would become not only a decompiler but a complete bridge between Radare2 and Ghidra after this project.

Special thanks should be given to my mentors, Florian Märkl, Giovanni, and Anton. Your patience and guidance are all well appreciated. I couldn’t have completed this project without your support.

Here’s the slides made for r2con2020.
