Hi Thomas,
However, I still don't understand why you insist on the hack with
putting the async_io_*.f90 tests into the libgomp testsuite. Why not
just make the pthread requirement explicit with
{ dg-require-effective-target pthread }
{ dg-additional-options "-pthread" }
and put them in gfortran.dg where they belong?
Because this does not appear to work with Linux. I, like
most gfortran developers, work on Linux, and I would like to
catch any failure during regression-testing on my own system,
if possible.
huh, what doesn't work? I've just finished an x86_64-pc-linux-gnu
bootstrap with your patch included, added the above to the
async_io_?.f90 tests, linked them to gfortran.dg and ran the tests there
(both 32 and 64-bit multilibs), all PASSed and I verified that they were
linked with -lpthread.
We have had this discussion with Jakub, and he advised
us to put all the stuff requiring pthreads into libgomp.
Do you have a pointer to that previous discussion?
It is debatable if this is a good thing, or if we should
at least make one round of tests with -pthread enabled.
However, this is something for the future, and requires knowledge
of dejagnu that I don't currently have :-)
First of all, we need to see and understand the failure mode, if any.
Making this work with the testsuite is a secondary matter only, and I
can certainly help with that if necessary.
