This file contains definitions of the various C++ operators,
|
|
including both overloadable operators (like `+') and
|
|
non-overloadable operators (like the `?:' ternary operator).

/* The DEF_OPERATOR macro takes the following arguments:
|
|
|
|
NAME
|
|
|
|
The name of the operator, as a C string, but without the
|
|
preceding `operator'. This is the name that would be given in
|
|
the source program. For `operator +', for example, this would be
|
|
`+'.
|
|
|
|
CODE
|
|
|
|
The tree_code for this operator. For `operator +', for example,
|
|
this would be PLUS_EXPR. Because there are no tree codes for
|
|
assignment operators, the same tree-codes are reused; i.e.,
|
|
`operator +' will also have PLUS_EXPR as its CODE.
|
|
|
|
NEW_MANGLING
|
|
|
|
The mangling prefix for the operator, as a C string, and as
|
|
mangled under the new ABI. For `operator +', for example, this
|
|
would be "pl".
|
|
|
|
ARITY
|
|
|
|
The arity of the operator, or -1 if any arity is allowed. (As
|
|
for `operator ()'.) Postincrement and postdecrement operators
|
|
are marked as binary.
|
|
|
|
ASSN_P
|
|
|
|
A boolean value. If non-zero, this is an assignment operator.
|
|
|
|
Before including this file, you should define DEFOPERATOR
|
|
to take these arguments.
|
|
|
|
There is code (such as in grok_op_properties) that depends on the
|
|
order the operators are presented in this file. In particular,
|
|
unary operators must precede binary operators. */
|
|
|

|
|
arguments are as for DEF_OPERATOR, but there is no need to provide
|
|
an ASSIGNMENT_P argument; it is always zero. */
