Definition at line 32 of file ldo.h.
| virtual expression_ldo::~expression_ldo | ( | ) | [virtual] |
The destructor.
| expression_ldo::expression_ldo | ( | const location & | locn, | |
| const type::pointer & | type, | |||
| unsigned | offset, | |||
| translator_compile * | cntxt | |||
| ) |
The constructor.
| locn | source location of this code | |
| type | the type of expression resulting from this code | |
| offset | the stack frame offset argument of this opcode | |
| cntxt | where to send our generated code |
| expression_ldo::expression_ldo | ( | ) | [private] |
The default constructor. Do not use.
| expression_ldo::expression_ldo | ( | const expression_ldo & | ) | [private] |
The copy constructor. Do not use.
| void expression_ldo::traversal | ( | int | pprec | ) | [protected, virtual] |
The traversal method may be used to traverse each of the declaractions in the list.
| pprec | The precedence of the parent expression node. |
Implements expression.
| expression::pointer expression_ldo::optimize | ( | ) | const [protected, virtual] |
The optimize method may be used to evaluate constant expressions, or substitute more efficient expressions.
This is intended to be called by the translator:: expression_statement method, or similar, where the expression is in its final form, and will get no deeper. In other words, when all available information has been provided.
There is no default implementation, even though most optimize implementations return self(), because this gives the compiler no opportunity to remind the authors of new classes that they have forgotten something.
Implements expression.
| void expression_ldo::logical_traversal | ( | int | pprec, | |
| label::pointer & | true_branch, | |||
| label::pointer & | false_branch, | |||
| bool | fall_through_preference | |||
| ) | [protected] |
| int expression_ldo::get_precedence | ( | ) | const [protected, virtual] |
The get_precedence method is used to obtain the precedence of this expression node.
The highest precedence has the highest absolute value, the lowest precedence gets the lowest absolute value.
Implements expression.
| type::pointer expression_ldo::get_type | ( | ) | const [protected, virtual] |
The get_type method is used to get the type of this expression.
Implements expression.
| bool expression_ldo::is_lvalue | ( | ) | const [protected, virtual] |
The is_lvalue method is used to determine whether or not this expression is suitable to appear on the left hand side of an assignment expression.
Implements expression.
| side_effect_t expression_ldo::has_side_effect | ( | ) | const [protected, virtual] |
The has_side_effect method is used to determine if an expression has any effect. It is used by the parse to produce "statement with no effect" warnings.
Implements expression.
| expression_ldo& expression_ldo::operator= | ( | const expression_ldo & | ) | [private] |
The assignment operator. Do not use.
translator_compile& expression_ldo::code [private] |
type::pointer expression_ldo::type [private] |
unsigned expression_ldo::offset [private] |
