Hi;
I am working my way through the compiling process. I want to be precise
about my question so that responders do not waste time on answering the
wrong question.
Where can I find/see which preprocessor, lexical analysiser, parser etc.
the gcc compliler is using in Fedora? What order are they being used in
and any other instructions or agruments that are being passed to them by
gcc (the compiler) besides the original/modified code?
This may be too onvious, and perhaps not understanding the question
fully, but it seems like you want to see the output of -v during a
compile. It shows each step, what process is called with what
arguments, and the global variables as set.
Here is a cc -v of a tiny c program:
-> cc -v h.c
