a question about program compilation and disk io

[Zou Min <zoum@comp.nus.edu.sg>]

Hi,

I would like to ask a question regarding to the number of disk reads
over a compilation workload in Linux.

For example, if the workload is "g++ -c xxx.c", except that "g++" program
and source code "xxx.c" will be loaded into memory, what else will be read 
from disk?

Thanks in advance!

Cheers!
