Hello, Jonas.
Thanks, I've added them to svn. I cursorily tested them and they at
least work under Mac OS X/x86_64 and Mac OS X/PowerPC.
Is it possible to test them under other platforms? SPARC, ARM,
PowerPC64?
The tests are part of the nightly test suite now, so they are tested
on all platforms for which nightly tests are performed. They seem to
have worked fine on all properly tested platforms (ARM is not one of
those though).
However, there is a problem you should know about. ALGLIB uses
non-deterministic unit tests. I.e. test sets are generated randomly
(instead of being built-in, pre-generated). This approach have both
benefits and drawbacks.
At the very least, the value of randseed should probably be written
out on startup so that the test can be reproduced under the same
circumstances if it fails.
So we have two options:
1. to use only the most stable units
2. to give me limited access to SVN so I may run these tests myself
and study their results.
I have enough time on my hands so I can help you with tests if you
want.
Everyone has read-only access to the tests in svn, since they're part
of the regular fpc svn repository: http://www.freepascal.org/develop.var#svn
To run the testsuite, first perform a "make clean all" in the FPC
directory, then change to the tests directory and run
make FPC=compiler_to_compile_testsuite_utilities TEST_FPC=/full/path/
to/fpc/compiler/ppc386 TEST_OPT="-O2 -Cppentiumm" clean all digest
(replace ppc386 with ppcx64 in case of x86_64 platforms, and the
contents of TEST_OPT with whatever options you want to use to compile
the tests). Afterwards, you an find a list of failed tests in output/
$fulltarget/faillist, and output/$fulltarget/longlong contains the
full compiler/test output).
This will always do a full testsuite run though (which takes quite a
while to complete, even on a fast machine). There's currently no way
to only execute a subset of the testsuite. The alglib tests are in
tests/test/alglib.
If you want, I can give you svn write access to tests/test/alglib so
you can easily add/change the tests there though.
