Talk:Bytecode
From Wikipedia, the free encyclopedia
Hey guys, you'd better point out some disadvantages of bytecode once you speak about its advantages!!
This article is, umm, rather incomprehensible to someone who doesn't already know everything about this topic. k.lee
Bytecode may be used as an intermediate code of a compiler, or may be the saved 'tokenized' form used by an interpreter
How can this sentence be related to virtual machine? -- HJH

Shouldn't the ByteCode Engineering Library link point to http://jakarta.apache.org/bcel/ as that page doesn't exist? - Jeremy Harmon
"Byte code", "byte-code", and "bytecode" seem to be fighting it out. Specifically, there is an entry for the Java Bytecode. Anyone have a strong preference as to which the final version should be? Charles Merriam 21:10, 4 February 2006 (UTC)

- I also vote for bytecode; a quick Google search seems to confirm its greater popularity. More importantly, "The Java Virtual Machine Specification" by Lindholm and Yellin (1997) spells it "bytecode". This is surely the ultimate reference, at least for the Java version. --Mike Van Emmerik 12:37, 11 February 2006 (UTC)
- Bytecode, definately. Wouter Lievens 12:51, 11 February 2006 (UTC)
- Bytecode, I don't think "byte" works as an adjective njaard 15:16, 23 March 2006 (UTC)
- Bytecode is more common. Obviously, make redirects. --Leapfrog314 04:58, 20 April 2006 (UTC)

"The current reference implementation of the Ruby programming language does not use bytecode, however it relies on tree-like structures which resemble intermediate representations used in compilers.". Is it relevant to talk about Ruby not using bytecode in this article? - Philoctet

[edit] incorrect use of term bytecode
I believe that this entire article is a misuse of the term bytecode. I have worked near machine level in computer science for many years, and in my experience, bytecode applies specifically to the Java Virtual Machine, whose instruction set does indeed consist of one-byte opcodes. For other programming languages, the correct term for what this article described is "intermediate language". Visual Basic compiles to an intermediate language, as did Pascal, Smalltalk, and others. These were NEVER to my knowledge called "bytecode."
I think this needs to be fixed, hopefully by the author of this article.
[edit] Layman's terms
I have to agree with the above comments about how the article needs to be easier to understand. I'm a part-time developer for various languages for the past 10 years. And I don't even understand what byte-code is, nor has this article helped. I'm not suggesting we compromise and make a 'for dummies' article, but just add a sentence here and there to help clarify.
[edit] Bytecode execution techniques?
This and virtual machine both don't explain any techniques used to execute bytecode. I've sketched some basic thoughts out on a blog entry of mine at KernelTrap; but I don't know how current day ones operate, if there's generally optimization, if instruction ordering counts, etc.
[edit] binary requirement
Could a textual language be considered bytecode? Obviously not, but this article lists CIL as an example of bytecode, and many other articles call it "bytecode". The article for CIL even calls it both "human-readable" and "bytecode". CIL example Herorev 21:22, 19 November 2006 (UTC)
