Dear all,
first, I want to wish all of you a happy New Year.
Attached you find a patch which calls _gfortran_caf_deregister for
allocatable coarrays - for -fcoarray=lib. In the caf libraray version,
coarrays are allocated/deallocated in the library. The
allocation/deallocation was working before for coarrays in static
memory ("SAVE") and the ALLOCATE ("register") of allocatable coarrays.
This patch adds the deallocation support ("deregister") both for
explicit (DEALLOCATE) as well as for the implicit deallocation (when
leaving the scope).
While implementing this, I fixed and changes some other items:
* The "token" which identifies the coarray in the library was not
properly implemented in the library.
* ERRMSG= of ALLOCATE/DEALLOCATE did not pad the string
* ALLOCATE of coarrays with -fcoarray=lib: The status and errmsg of
_gfortran_caf_register were overridden.
Instead of counting the deallocate failures, we now directly abort,
which makes life a bit easier which coarrays. (Without coarrays, the
only failure can be that the variable is already deallocated as
"free()" does not give an error and we currently do not check whether
pointer targets may be deallocated. With coarrays, additional issues
can occur.)
Build and regtested on x86-64-linux.
OK for the trunk?
