D	rationale-for-bytecode.md	1 # Rationale for Bytecode 5 This document sets up some context about bytecode design principles and provides rationales for 6 bytecode design in Panda Runtime. 8 ## Bytecode basics 10 Before discussing bytecode per se, let's take a look at an over-simplified picture of a real 26 Here comes the bytecode. Simply said, it is an attempt to build an abstract CPU on top of real 29 commands (or bytecode) and execute them. Of course, this implies additional performance overhead 35 Although bytecode represents some abstraction, it mirrors all the mentioned concepts from the 41 building bytecode. Following sections explain advantages and disadvantages of various approaches. 78 each bytecode instruction, execute it and move to the next one, running more instruction results in [all …]

Program execution via bytecode interpretation should be enabled on all targets. 29 ## Bytecode section in Interpreter Design 33 1. Bytecode should allow the interpreter to run no slower than state of the art interpreters. 34 1. Bytecode should be compact in size to avoid bloating application code. 35 1. Bytecode description should have a single entry point to simplify maintenance 40 1. Bytecode is register-based: all arguments and variables are mapped to virtual registers, 44 1. Bytecode's instruction set architecture is machine-readable with a dedicated API for 49 For the rationale on the bytecode type, please see [here](rationale-for-bytecode.md). 51 Rationale on the machine-readable instruction set architecture is following.
