Method Detail

getProgram

public Program getProgram()

invalidateBlock

public void invalidateBlock(int addr)

The invalidateBlock() method invalidates any compiled copies of the block that contains the specified program address. This might be called as the result of a write to program memory (flash update) or insertion of a probe into the middle of a basic block.

Parameters:

addr - the byte address for which the enclosing block should be invalidated

getCompiledBlock

public DBBC.CompiledBlock getCompiledBlock(int addr)
                                    throws java.lang.Exception

The getCompiledBlock() method instructs the DBBC to compile the basic block that begins at the specified byte address.

Parameters:

addr - the byte address of the beginning of the basic block to compile

Returns:

a reference to the compiled block of code when complete

Throws:

java.lang.Exception

getCodeBlock

public DBBC.CodeBlock getCodeBlock(int addr)

generateClassForCode

protected java.io.File generateClassForCode(int addr,
                                            java.util.List stmts,
                                            int wcet)
                                     throws java.lang.Exception

Throws:

java.lang.Exception

getCompiledBlock

public DBBC.CompiledBlock getCompiledBlock(DBBC.CodeBlock b)
                                    throws java.lang.Exception

Throws:

java.lang.Exception

compileGeneratedCode

protected java.io.File compileGeneratedCode(java.io.File f)
                                     throws java.lang.Exception
