2011-07-07 Tobias Burnus <burnus@net-b.de> * trans.c (gfc_allocate_with_status): Call _gfortran_caf_register with NULL arguments for (new) stat=/errmsg= arguments. 2011-07-07 Tobias Burnus <burnus@net-b.de> * libcaf.h (__attribute__, unlikely, likely): New macros. (caf_register_t): Update comment. (_gfortran_caf_register): Add stat, errmsg, errmsg_len arguments. * single.c (_gfortran_caf_register): Ditto; add error diagnostics. * mpi.c (_gfortran_caf_register): Ditto.
