In embodiments, prior to compilation into machine code, a preprocessor generates directives by processing a source code and/or bytecode representation of a program and/or selecting default directives. The preprocessor embeds the directives in a bytecode representation of the program or a separate stream associated with the bytecode representation of the program. A just-in-time compiler may compile the bytecode representation into machine code directed by the embedded directives in one pass and/or a bytecode interpreter may interpret the bytecode representation of the program. In some embodiments, a computing device generates bytecodes during execution of a program, selects default directives, and embeds the default directives in the bytecodes or a separate stream associated with the bytecodes prior to compilation of the bytecodes into machine code. Subsequently, the bytecodes may be compiled into machine code with a just-in-time compiler directed by the embedded default directives in one pass and/or interpreted with an interpreter.
