Test report for Steven Bosscher's patch posted to ![[WWW]](/wiki/modern/img/moin-www.png){kind=small}
gelato-gcc on June 26 2005.
I ran the SPEC suite on an HP rx2600 with two 1.3GHz/6m Itanium 2 CPUs. This system has 8GB of memory.
This was not an official run, as three benchmarks (gcc, parser, and galgel) did not compile properly.
I applied the patch to a clean checkout of the GCC CVS tree as of June 27 2005. I ran two sets of tests:
A non-profiled test (-O3 -funroll-loops) for both the standard and patched trees.
A profiled test (-O3 -fprofile-arcs/-fbranch-probabilities -funroll-all-loops -fpeel-loops) for both trees.
Note: The profiled test used statically linked binaries, while the non-profiled test used dynamically linked ones. I'm running a new test to use dynamically linked binaries with the profiled test to get more consistent numbers.
