This file contains definitions of the various C++ operators,
|
| 4 |
|
|
including both overloadable operators (like `+') and
|
| 5 |
|
|
non-overloadable operators (like the `?:' ternary operator).

/* The DEF_OPERATOR macro takes the following arguments:
|
| 28 |
|
|
|
| 29 |
|
|
NAME
|
| 30 |
|
|
|
| 31 |
|
|
The name of the operator, as a C string, but without the
|
| 32 |
|
|
preceding `operator'. 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. Its
|
| 67 |
|
|
arguments are as for DEF_OPERATOR, but there is no need to provide
|
| 68 |
|
|
an ASSIGNMENT_P argument; it is always zero. */
