Question about TCG backend correctness

[LIU Zhiwei]

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.

Best Regards,
