One thing that would certainly help as a foundation for possible
further improvement in performance in this area would be to have
xgcc contain all the front ends directly linked into it.
That does seem debatable.
It could be a starting point to help avoiding quite a lot of
overhead needed to iterate over command line options for example.
Odd. You think that time is being spent iterating over the command
line options? Do you have any data points to back this up? I suspect
we're spending less than 0.01% of the compilation time in duplicative
argument processing. After a quick check, yup, 0ms out of 1158 ms are
spent in option processing. 11 ms in xgcc, 1 ms in all of xgcc, and
10 ms in system calls. So, I think due to measurement error, I can
say that no more than 0.17% of the time is spent in duplicative option
processing.
