This is a C++ RISC-V emulator that focuses on isolating a single process, aka userspace emulation. I am currently working mostly on binary translation, and recently I have made a push to move it from experimental state to fully supported. Another experimental feature is embedding libtcc and using that for binary translation. It is fairly fast to compile, and gives decent speedups. The challenge is what to do now that (perhaps) some low hanging fruits have been picked.

I definitely recommend people to consider the base ISA of RISC-V if they want to try to implement a CPU or even full-system emulation. I understand that implementing a GameBoy emulator might be more attractive because you are working towards something graphical, but you can definitely get something similar with RISC-V, eg. Doom (SDL example: https://github.com/fwsGonzo/libriscv/tree/master/examples/do...)

This is the example project: https://github.com/fwsGonzo/libriscv/tree/master/examples/msvc

Pretty much two days of work: https://github.com/fwsGonzo/libriscv/commits/master

There is a doom emulation demo here now: https://github.com/fwsGonzo/libriscv/tree/master/emulator/do...

You will need to add the shareware doom1.wad yourself. :)

CLion uses lldb.

I wrote https://github.com/daym/idea-native2-debugger as a stop-gap. It uses gdb and works in IntelliJ IDEA Community edition. Setting it up the first time is kinda weird since you need to add a new run/debug configuration "Native2Debugger". I could not figure out how to hook this directly into the existing run configuration that you use to run your program to begin with. Otherwise, I like how it turned out.

If you want a standalone frontend, https://github.com/epasveer/seer is extremely good.

And emacs has gdb integration. By now I tried it, and... I guess it's better than nothing.

(Shameless plug for my frontend to gdb --> https://github.com/epasveer/seer )
