Dear gcc developers,
I found that it is essentially it is cc1plus does the compilation work
for preprocessed cpp files.
/usr/local/libexec/gcc/i686-pc-linux-gnu/4.1.1/cc1plus test.i.cc.
At the end, cc1plush will print out some statistical info as the end of this
email shows. Beside the source code, Is there any documentation around
that describe these stages? The gcc internals does not talk much about this.
Many thanks,
- Andy
