Hello,
I have tested the port from
http://people.freebsd.org/~jkim/path64-devel-20111117.tar.bz2 and
http://people.freebsd.org/~jkim/path64-20111115.tar.xz but the compiler failed
in the following tests:
3/6 Test #3: regression_tests .................***Failed 0.81 sec
Start 4: hello_c
4/6 Test #4: hello_c .......................... Passed 0.14 sec
Start 5: hello_cpp
5/6 Test #5: hello_cpp ........................ Passed 0.67 sec
Start 6: path64_bootstrap_test
6/6 Test #6: path64_bootstrap_test ............***Failed 42.28 sec
67% tests passed, 2 tests failed out of 6
Total Test time (real) = 44.74 sec
The following tests FAILED:
3 - regression_tests (Failed)
6 - path64_bootstrap_test (Failed)
Errors while running CTest
Are these known errors for that build?
Normally I'd bug you about using vanilla upstream, but in this case I
think JK's branch is in better shape. (Apologies about not merging it
yet, but we have a QA project we'll be testing it with and open sourcing
soon - compiler agnostic fwiw)
Specifically about your question - It's probably unexpected and I'm
curious what processor and version of FBSD this is.
I also tested it on a fortran code. Here is the runtime result:
0.923u /usr/local/path64/bin/pathf95 -O3 -LANG:copyinout=ON:recursive=ON
-OPT:goto=ON
1.283u gfortran46 -O3
I actually compiled gfortran with CLooG-PPL but the optimization flags from
GRAPHITE does not change the run time of this code.
Am I reading the result correctly that we're faster? You may also want
to add/test -ipa to your flags..
Side notes :
1) -ipa == LTO in gcc which I don't know if it works at all on FBSD
(We have some linker work that may help this situation in the future)
2) I don't care what others say - Graphite isn't afaik production
ready so *if* you ever do see any performance gains from it - ensure
that you strongly validate before using in production setup
3) We've added the latest User Guide online -

Thanks a lot for testing!
