2105 2009-01-17 Paul Thomas <pault@gcc.gnu.org>
2108 * trans-intrinsic.c (gfc_conv_intrinsic_array_transfer): Has
2109 been absorbed into gfc_conv_intrinsic_transfer. All
2110 references to it in trans-intrinsic.c have been changed
2111 accordingly. PR fixed by using a temporary for scalar
2112 character transfer, when the source is shorter than the

2137 2009-01-10 Paul Thomas <pault@gcc.gnu.org>
2140 * resolve.c (check_host_association): Use the symtree name to
2141 search for a potential contained procedure, since this is the
2142 name by which it would be referenced.
2144 2009-01-06 Thomas Koenig <tkoenig@gcc.gnu.org>
2147 * interface.c (gfc_procedure_use): Don't warn about functions
2149 * symbol.c (generate_isocbinding_symbol): Mark c_loc and
2152 2009-01-05 Paul Thomas <pault@gcc.gnu.org>
2155 * module.c (write_common_0): Use the name of the symtree rather

2179 * resolve.c (check_host_association): Return if above is set.
2181 2009-01-04 Mikael Morin <mikael.morin@tele2.fr>
2184 * ChangeLog-2008: Fix function name.
2187 * dependency.c (gfc_check_argument_var_dependency):
2188 Move the check for pointerness inside the if block
2189 so that it doesn't affect the return value.
2192 * trans-stmt.c (gfc_trans_call):
2193 Add the dependency code after the loop bounds calculation one.
