This is a good start for debugging a tcg backend.
After fixing some bugs, RISU can run some instructions now.

I'd be surprised if you don't wind up with a similar amount of code a

This is a good start for debugging a tcg backend. It's not comprehensive, because RISU
executes one instruction at a time then raises an exception to check the r

Hi folks,
For TCG front end, we can test it with tools, such as RISU. But I
don't know if there are some tools that can help
to verify the correctness of a TCG backend.
Can someone share the tools or the experience to debug RISC-V
backend? Thanks very much.
