- Subject: [PATCH] Cray pointers to procedures
:ADDPATCH fortran:
A while back, there was a discussion on comp.lang.fortran regarding
Cray pointers to procedures:
http://groups.google.com/group/comp.lang.fortran/browse_frm/thread/c0528d0a3d4fd41a/
Attached is a short patch that implements this in gfortran. This is
very non-standard; ifort accepts Cray pointers to procedures, while
pgf90, xlf90, and Pathscale reject them. I don't think these are
widely used, but as the attached patch shows, the basic functionality
is already there, so this feature is essentially free. This patch
was bootstrapped and regression tested on x86 and x86_64 Linux.

* symbol.c (check_conflict): Allow external, function, and
subroutine attributes with Cray
pointees.
* trans-expr.c (gfc_conv_function_val): Translate Cray
pointees that point to procedures.
