From: Jakub Jelinek Date: Wed, 9 Apr 2008 09:00:31 +0000 (+0200) Subject: list_read.c (snprintf): Define if HAVE_SNPRINTF isn't defined. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=24722ea98e979fd3c7a0e82c8f422544fa5cd947;p=gcc.git list_read.c (snprintf): Define if HAVE_SNPRINTF isn't defined. * io/list_read.c (snprintf): Define if HAVE_SNPRINTF isn't defined. (nml_read_obj): Add nml_err_msg_size argument. Pass it down to recursive call. Use snprintf instead of sprintf when %s nl->var_name is used. (nml_get_obj_data): Add nml_err_msg_size argument. Pass it down to nml_read_obj call. Use snprintf instead of sprintf when %s nl->var_name is used. Pass nml_err_msg to nml_parse_qualifier instead of parse_err_msg array. Append " for namelist variable " and nl->var_name to it. (namelist_read): Increase size of nml_err_msg array to 200. Pass sizeof nml_err_msg as extra argument to nml_get_obj_data. * gfortran.dg/namelist_47.f90: New test.
