Method Detail

invoke

public java.lang.String invoke(LirNode node)

invoke: the method that you should call it first.

Parameters:

node - the root node that will convert to C code.

Returns:

the C string of lir nodes.

dump

java.lang.String dump(LirNode node,
                      boolean inMEM,
                      LirNode parent)

dump: main method of the convertion. it called by invoke method and dump method(dump method calls dump method recursively).

Parameters:

node - the node that will convert to a part of C code.

inMEM - the boolean value which node are in MEM expression.

parent - the node that is a parent of the node.

Returns:

the string that is a part of C code.

lirToTypeStr

java.lang.String lirToTypeStr(LirNode node)

lirToTypeStr: get type string of the variable, expression, etc by calling coins.backend.Type@toString() method. note: aggregate objects do not support.

Parameters:

node - the node to get the type string.

Returns:

the type string of LirNode.

lirToTypeStr2

java.lang.String lirToTypeStr2(LirNode node)

lirToTypeStr2: get type string of the variable, expression, etc by calling coins.backend.Type@toString() method. note: aggregate objects do not support(return "").

Parameters:

node - the node to get the type string.

Returns:

the type string of LirNode.

lirToTypeStr3

java.lang.String lirToTypeStr3(LirNode node)

lirToTypeStr3: get type string and parenthes of the variable, expression, etc by calling coins.backend.Type@toString() method. note: if the node is aggregate object, return "".

Parameters:

node - the node to get the type string.

Returns:

the type string and parenthes of LirNode.

biOpToStr

java.lang.String biOpToStr(LirNode node,
                           LirNode child1,
                           LirNode child2,
                           java.lang.String Ope,
                           boolean inMEM,
                           LirNode parent)

biOpToStr: get the expression of C code for bi Operator node(ADD,etc).

Parameters:

node - the node to convert.

child1 - the node of first child node.

child2 - the node of second child node.

inMEM - the node that is in the MEM expression is true, or false.

parent - the node that is a parent of the node.

Returns:

the C code for the node.
