1/* -*-C-*- 2 3 This file contains definitions of the various C++ operators, 4 including both overloadable operators (like `+') and 5 non-overloadable operators (like the `?:' ternary operator). 6 Written by Mark Mitchell <mark@codesourcery.com> 7 8 Copyright (C) 2000, 2001, 2002, 2003, 2005, 2007, 2008, 2009 9 Free Software Foundation, Inc. 10 11This file is part of GCC. 12 13GCC is free software; you can redistribute it and/or modify 14it under the terms of the GNU General Public License as published by 15the Free Software Foundation; either version 3, or (at your option) 16any later version. 17 18GCC is distributed in the hope that it will be useful, 19but WITHOUT ANY WARRANTY; without even the implied warranty of 20MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This is the name that would be given in 33 the source program. For `operator +', for example, this would be 34 `+'. 35 36 CODE 37 38 The tree_code for this operator. For `operator +', for example, 39 this would be PLUS_EXPR. Because there are no tree codes for 40 assignment operators, the same tree-codes are reused; i.e., 41 `operator +' will also have PLUS_EXPR as its CODE. 42 43 MANGLING 44 45 The mangling prefix for the operator, as a C string, and as 46 mangled under the new ABI. For `operator +', for example, this 47 would be "pl". 48 49 ARITY 50 51 The arity of the operator, or -1 if any arity is allowed. (As 52 for `operator ()'.) Postincrement and postdecrement operators 53 are marked as binary. 54 55 ASSN_P 56 57 A boolean value. If nonzero, this is an assignment operator. 58 59 Before including this file, you should define DEF_OPERATOR 60 to take these arguments. 61 62 There is code (such as in grok_op_properties) that depends on the 63 order the operators are presented in this file. In particular, 64 unary operators must precede binary operators. */ 65 66/* Use DEF_SIMPLE_OPERATOR to define a non-assignment operator.
