ToHirSym

ToHirSym(ToHir tohir)

Constructor.

Parameters:

tohir - Offers cooperation with the object of other packages.

Method Detail

makeQualifiedTypes

void makeQualifiedTypes(Type t,
                        java.lang.String tagname)

make qualified types of t (=struct or union which has tag of tagname). The qualified type of t might be defined while t is an incomplete type. To define the qualified type of t as a complete type again when t became a complete type, this method is called.

Parameters:

t - complete type (struct or union)

tagname - tag name of the complete type

convertType

public Type convertType(byte[] b,
                        boolean pLocal)

Convert type. Created type symbol is added appropriate symbol table.

Parameters:

b - AST type information byte array.

Returns:

HIR type.

getNormalTable

public SymTable getNormalTable()

Get normal (block scope or global) symbol table other than SymTable owned by STRUCT, UNION, ENUM.

Returns:

Normal symbol table.

declareType

void declareType(Type type,
                 java.lang.String name)

Declare type (=typedef). Create type symbol and add into symTableCurrent.

Parameters:

type - Type of the symbol.

name - Name of the symbol.

declareGlobalFunction

Subp declareGlobalFunction(int storage,
                           SubpType type,
                           java.lang.String name,
                           boolean init)

Declare function at global scope. Create subprogram symbol and add into symTableRoot.

Parameters:

storage - AST storage class.

type - HIR SubpType object.

name - Function name.

init - True if declaration has function body.

Returns:

Declared Subp.

declareLocalFunction

Subp declareLocalFunction(int storage,
                          SubpType type,
                          java.lang.String name)

Declare function at local scope. Create subprogram symbol and add into symTableCurrent.

Parameters:

type - HIR SubpType object.

name - Function name.

Returns:

Declared Subp.

declareGlobalVariable

Var declareGlobalVariable(int storage,
                          Type type,
                          java.lang.String name,
                          Expr ini)

Declare variable at global scope. Create variable symbol and add into symTableRoot.

Parameters:

                         Type type,
                         java.lang.String name,
                         Expr ini)
