OP_EXTENDED0 is now also provided by operator.def. * expprint.c (op_name_standard): Include "operator.def" instead of "std-operator.def". This introduces a small change of behavior, in the fact that op_name_standard will now recognize Ada operators. But this function is about to be renamed to "op_name", so I think it's OK. --- gdb/ada-operator.def | 99 ------------ gdb/expprint.c | 2 +- gdb/expression.h | 12 +-- gdb/operator.def | 414 ++++++++++++++++++++++++++++++++++++++++++++++++++ gdb/std-operator.def | 328 --------------------------------------- 5 files changed, 416 insertions(+), 439 deletions(-) delete mode 100644 gdb/ada-operator.def create mode 100644 gdb/operator.def delete mode 100644 gdb/std-operator.def diff --git a/gdb/ada-operator.def b/gdb/ada-operator.def deleted file mode 100644 index 8738250..0000000 --- a/gdb/ada-operator.def +++ /dev/null @@ -1,99 +0,0 @@ -/* Ada language operator definitions for GDB, the GNU debugger. - - Copyright (C) 1992, 1997-2005, 2007-2012 Free Software Foundation, - Inc. - - This file is part of GDB. - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 3 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
