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

Hi Guys,
 
 
 
       Can we build risv-32 gcc compiler from official gcc repository ?









Yes, lots of people do that.








Thanks,

 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.

 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).

 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,
