The gcc driver execs another program, which for C is called cc1. The main function in cc1 winds up calling the parser. To see how, run gcc -v to see how cc1 is invoked, and run gdb on cc1, set a breakpoint, and do a backtrace. > I looked at the > YACC/BISON file and found that c_parse_file called yyparse(). Note that this is gone in current gcc sources. The parser has been rewritten to use recursive descent rather than bison. Ian
