addNullIfVoid

public void addNullIfVoid()

atMember

public void atMember(Member mem)
              throws CompileError

Overrides:

atMember in class MemberCodeGen

Throws:

CompileError

atCastExpr

public void atCastExpr(CastExpr expr)
                throws CompileError

Overrides:

atCastExpr in class CodeGen

Throws:

CompileError

isParamListName

public boolean isParamListName(ASTList args)

atMethodArgsLength

public int atMethodArgsLength(ASTList args)

Overrides:

atMethodArgsLength in class MemberCodeGen

atMethodArgs

public void atMethodArgs(ASTList args,
                         int[] types,
                         int[] dims,
                         java.lang.String[] cnames)
                  throws CompileError

Overrides:

atMethodArgs in class MemberCodeGen

Throws:

CompileError

recordReturnType

public int recordReturnType(CompileTimeClass type,
                            java.lang.String castName,
                            java.lang.String resultName,
                            SymbolTable tbl)
                     throws CompileError

Makes a cast to the return type ($r) available. It also enables $_.

If the return type is void, ($r) does nothing. The type of $_ is java.lang.Object.

Parameters:

resultName - null if $_ is not used.

Returns:

-1 or the variable index assigned to $_.

Throws:

CompileError

recordType

public void recordType(CompileTimeClass t)

Makes $type available.

recordParams

public void recordParams(CompileTimeClass[] params,
                         boolean isStatic,
                         java.lang.String prefix,
                         java.lang.String paramVarName,
                         java.lang.String paramsName,
                         SymbolTable tbl)
                  throws CompileError

Makes method parameters $0, $1, ..., $args, and $$ available. $0 is equivalent to THIS if the method is not static. Otherwise, if the method is static, then $0 is not available.

Throws:

CompileError

recordParams

public void recordParams(CompileTimeClass[] params,
                         boolean isStatic,
                         java.lang.String prefix,
                         java.lang.String paramVarName,
                         java.lang.String paramsName,
                         boolean use0,
                         int paramBase,
                         java.lang.String target,
                         SymbolTable tbl)
                  throws CompileError

Makes method parameters $0, $1, ..., $args, and $$ available. $0 is available only if use0 is true. It might not be equivalent to THIS.

Parameters:

paramBase - the register number of $0 (use0 is true) or $1 (otherwise).

target - the class of $0. If use0 is false, target can be null.

isStatic - true if the method in which the compiled bytecode is embedded is static.

Throws:

CompileError

recordVariable

public int recordVariable(CompileTimeClass type,
                          java.lang.String varName,
                          SymbolTable tbl)
                   throws CompileError

Makes the given variable name available.

Parameters:

type - variable type

varName - variable name

Throws:

CompileError

compileParameterList

public static int compileParameterList(Bytecode code,
                                       CompileTimeClass[] params,
                                       int regno)

setType

public void setType(CompileTimeClass type)
             throws CompileError

Throws:

CompileError

doNumCast

public void doNumCast(CompileTimeClass type)
               throws CompileError

Throws:

CompileError
