From 8b3af95e3ed31b3dcf54ca1d3aa5ab12b009acf1 Mon Sep 17 00:00:00 2001 From: Jan Kratochvil Date: Tue, 1 Feb 2011 18:53:58 +0000 Subject: gdb/ Fix debug printing of BINOP_IN, OP_OBJC_MSGCALL, OP_F77_UNDETERMINED_ARGLIST, OP_COMPLEX, OP_OBJC_SELECTOR, OP_NAME, OP_OBJC_NSSTRING, OP_F90_RANGE and OP_DECFLOAT. * ada-operator.inc: Rename the file to ... * ada-operator.def: ... here, wrap all the entries by macro OP. * expprint.c (op_name_standard): Remove all the entries. Include "std-operator.def" instead. * expression.h (enum exp_opcode): Include "std-operator.def" and "ada-operator.def". Move all the entries ... * std-operator.def: ... here, wrap all the entries by macro OP. --- gdb/std-operator.def | 327 +++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 327 insertions(+) create mode 100644 gdb/std-operator.def (limited to 'gdb/std-operator.def') diff --git a/gdb/std-operator.def b/gdb/std-operator.def new file mode 100644 index 00000000000..267215c8e8b --- /dev/null +++ b/gdb/std-operator.def @@ -0,0 +1,327 @@ +/* Standard language operator definitions for GDB, the GNU debugger. + + Copyright (C) 1986, 1989, 1992, 1994, 2000, 2003, 2005, 2007, 2008, 2009, + 2010, 2011 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.
