i am trying to port a front end to gcc, and i am confused with the gc, i see from the file gengtype.c, it can generate many files automaticlly, but i don`t understand the rule to generate it, i can only understand firstly use the yacc to analysize the gtfiles, then output something , and this is just what i don`t understand.
can some one tell me about it, or tell me where i can get more information about it. thanks a lot.
