Thanks for your reply. Is there some guide for building rv32 cross compiler gcc ? I encounter some error in the building progress.

Yes, lots of people do that.

But the GCC code is hard to understand. We are delighted you found looking into GCC interesting. I definitely agree that GCC source can be hard to read, especially for newcomers but often even for seasoned contributors when they look at a part they are not familiar with. But when you manage to manage to overcome the difficulty, the project can be very rewarding. And so not hesitate to ask us any specific question you may have here on the mailing list or on IRC. > I'm reading the c compiler of GCC.

Intermediate representations like GENERIC, GIMPLE and RTL are indeed fundamental. In order to see the representation of instructions, compile a simple program with option -fdump-tree-all and examine the many files that will appear in your working directory (representation of things like aggregate data types is unfortunately somewhat missing). > > Do you have some advice for GCC beginner?

David Malcolm wrote a very nice set of tutorials about various aspects of starting with GCC: https://gcc-newbies-guide.readthedocs.io/en/latest/ I believe that is the best generic resource there is. Good luck, Martin
