Hi, this patch resolves an ICE for Fortran when using the OpenACC
host_data directive. Actually, rather than say resolve, it's more like
adjusting the front-end to same middle-end restrictions as C/C++,
namely that we only support pointers or arrays for host_data right now.
This patch contains a little bit of adjustments in fortran/openmp.c:resolve_omp_clauses(),
and some testcase adjustments. This has been tested without regressions for Fortran.
Is this okay for trunk?
Thanks,
Chung-Lin

Fortran has it's own ChangeLog. The patch itself looks somewhat plausible to me, fwiw, but Jakub or a FE maintainer has the say.

Hi Chung-Lin,
I was ignoring your patch on the grounds that one of the omp gurus
should deal with it. That says, it looks OK for trunk to me.
I presume that fortran/host_data-1.f90 should have the XFAIL removed?
Cheers
Paul

As has been mentioned earlier, this should go into gcc/fortran/ChangeLog

This is too ugly. I'd instead move the if after the cray pointer/pointee
tests, i.e.
if (n->sym->attr.cray_pointer)
gfc_error (...);
else if (n->sym->attr.cray_pointee)
gfc_error (...);
else if (n->sym->attr.flavor == FL_VARIABLE
&& !n->sym->as
&& !n->sym->attr.pointer)
gfc_error (...);

Why pointer rather than POINTER ?

And, doesn't this mean you emit 2 errors, the first one because it is not
a pointer nor array, and the second one because it is a class with
attr.class_pointer? Also put && on the next line.
I think best would be to make it else if after the cray pointer/pointee
checks.
