Hello Everyone,
I am trying to understand GCC further, and I would like to know how
GCC calls the parser from the main function in gcc.c. I looked at the
YACC/BISON file and found that c_parse_file called yyparse(). Can
anyone please tell me which function calls c_parse_file and how I can
get to that file from the main function? Similarly, I owuld like to
know how it reaches the functions in passes.c

I am compiling my programs using -O3 optimization.

Any help is highly appreciated.

Thanks,

Balaji V. Iyer.
