I would also like to know the preferred method of testing compilation
speed. Possibilities include using the time utility, or GCC's
-ftime-report, which prints information about the time used by each
pass. People with access to platform-dependent tools are also using
those to gather specific kinds of information, as David Edelsohn did
with cache misses on AIX.
The release criteria include testing compile-time performance and peak
memory usage; see http://gcc.gnu.org/gcc-3.1/criteria.html. The only
source code listed is a GCC source file. As people do compile-time
testing they should consider proposing more tests to include in the
release criteria, along with specific methods of measurement.
