Hi all,
during development on OpenCoarrays I found these three issues in gfortran:
- caf_send: Did not treat char arrays as arrays when calling caf_send.
- gfc_trans_assignment_1: Conversion of character kind creates a loop variant
temporary which must not be put before the loop body, but within.
- get_array_span: When doing pointer arithmetic on char arrays the character
kind was not applied.
The attached patch fixes all of these issues for trunk and gcc-7. Bootstrapped
and regtested on x86_64-linux-gnu/f25. Ok for trunk and gcc-7?
Regards,
Andre

gcc/fortran/ChangeLog:
2017-11-01 Andre Vehreschild <ve...@gcc.gnu.org>
* trans-expr.c (gfc_trans_assignment_1): Character kind conversion may
create a loop variant temporary, too.
* trans-intrinsic.c (conv_caf_send): Treat char arrays as arrays and
not as scalars.
* trans.c (get_array_span): Take the character kind into account when
doing pointer arithmetic.

* gfortran.dg/coarray/send_char_array_1.f90: New test.
