3078 * resolve.c (resolve_symbol): Likewise.
3080 2009-01-05 Paul Thomas <pault@gcc.gnu.org>
3083 * gfortran.h : Add bit to gfc_expr 'user_operator'
3084 * interface.c (gfc_extend_expr): Set the above if the operator
3085 is substituted by a function.
3086 * resolve.c (check_host_association): Return if above is set.
3088 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
3091 * ChangeLog-2008: Fix function name.
3094 * dependency.c (gfc_check_argument_var_dependency):
3095 Move the check for pointerness inside the if block
3096 so that it doesn't affect the return value.
3099 * trans-stmt.c (gfc_trans_call):
3100 Add the dependency code after the loop bounds calculation one.
3102 2009-01-04 Daniel Franke <franke.daniel@gmail.com>
3104 * intrinsic.c (do_simplify): Removed already implemented TODO.
3106 2009-01-04 Daniel Franke <franke.daniel@gmail.com>
3109 * simplify.c (gfc_simplify_merge): New.
3110 * intrinsic.h (gfc_simplify_merge): New prototype.
3111 * intrinsic.c (add_functions): Added simplification for MERGE.
3113 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
3116 * gfortran.h (gfc_is_data_pointer): Added prototype
3117 * resolve.c (gfc_iso_c_func_interface):
3118 Use gfc_is_data_pointer to test for pointer attribute.
3119 * dependency.c (gfc_is_data_pointer):
3120 Support pointer-returning functions.
3122 2009-01-03 Daniel Franke <franke.daniel@gmail.com>
3124 * symbol.c (save_symbol): Don't SAVE function results.
3126 2009-01-03 Paul Thomas <pault@gcc.gnu.org>
3129 * resolve.c (resolve_call): When searching for proper host
3130 association, use symtree rather than symbol. For everything
3131 except generic subroutines, substitute the symtree in the call
3132 rather than the symbol.
