wyil.lang

Class Bytecode.Debug

java.lang.Object

wyil.util.AbstractBytecode

wyil.lang.Bytecode.Debug

All Implemented Interfaces:

Bytecode, Bytecode.Stmt

Enclosing interface:

Bytecode

public static final class Bytecode.Debug
extends AbstractBytecode
implements Bytecode.Stmt

A debug bytecode has the following layout:

 +--------+--------+
 | opcode | string |
 +--------+--------+
 

Here, the string identifies an operand returning a string result which will be printed to the debug console.

NOTE This bytecode is not intended to form part of the program's operation. Rather, it is to facilitate debugging within functions (since they cannot have side-effects). Furthermore, if debugging is disabled, this bytecode is a nop.
