From: Harald Anlauf <anlauf@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc r12-2915] Fortran: fix checks for STAT= and ERRMSG= arguments of SYNC ALL/SYNC IMAGES Date: Sun, 15 Aug 2021 18:13:36 +0000 (GMT) [thread overview] Message-ID: <20210815181336.B87D33858C3A@sourceware.org> (raw) https://gcc.gnu.org/g:bbf19f9c20515da9fcd23f08c8139427374e8d77 commit r12-2915-gbbf19f9c20515da9fcd23f08c8139427374e8d77 Author: Harald Anlauf <anlauf@gmx.de> Date: Sun Aug 15 20:13:11 2021 +0200 Fortran: fix checks for STAT= and ERRMSG= arguments of SYNC ALL/SYNC IMAGES gcc/fortran/ChangeLog: PR fortran/99351 * match.c (sync_statement): Replace %v code by %e in gfc_match to allow for function references as STAT and ERRMSG arguments. * resolve.c (resolve_sync): Adjust checks of STAT= and ERRMSG= to being definable arguments. Function references with a data pointer result are accepted. * trans-stmt.c (gfc_trans_sync): Adjust assertion. gcc/testsuite/ChangeLog: PR fortran/99351 * gfortran.dg/coarray_sync.f90: New test. * gfortran.dg/coarray_3.f90: Adjust error messages.
