Run time Debugging

Question

We have recently downloaded, installed and compiled gcc-3.0.4 code. gcc compiler has built successfully and we where able to compile some same test cpp file. I would like to know how we can modify gcc source code so that we add additional run time debugging statements like the binary in execution compiled by my gcc should print below statement in a log file:

filename.cpp::FunctionName#linenumber-statement

or any additional information that I can insert via this tailored compiler code Any references would be highly appreciable.

Answer 1

Have you looked at the macros __FILE__ and __LINE__? They do that for you without modifying the compiler. See here for more information.

My general understand of the GCC architecture is, that it is divided into front-end (parser), middle (optimization in a special intermediate language), and a back-end (generating platform dependent output). So, for your purposes you would have to look into the back-end part.
