Yes. read *.texi, then *.def, then *.h, then *.c, and you will know
much. Also, there is an entire web site devoded to the compiler at
gcc.gnu.org; under `manual' you will find most of *.texi.

emacs and gdb under emacs.

If you randomly pick 4 screens of code, you have a > 94% chance of
finding code that optimizes. In emacs, do a meta-x grep optimize *.c,
I am sure it will provide quite a few.
