[Pharo-project] Bytecode reference ...
Hi All, I'm wondering if you can help me just a little with some information. With Pharo I can dump the human readable form of Smalltalk bytecodes, like this: 21 <41> pushLit: ContextPart 22 <D0> send: primitiveFailToken 23 <7C> returnTop Can someone please point me to a document that outlines what each bytecode means? ie: <41> <D0> <7C> I can essentially see from the dump, but a proper reference would really help. Rgs, James.
Hi, I think you'll find ultimate guide for bytecodes in smalltalk's blue book at chapter 28, it gives you all the details: http://stephane.ducasse.free.fr/FreeBooks/BlueBook/Bluebook.pdf if you want just a quick reference, look at InstructionStream>>#interpretNextInstructionFor: and Interpreter class>>#initializeBytecodeTable (Interpreter class is downloaded when installing VMMaker).

For an up-to-date reference look at InstructionStream>>interpretNextInstructionFor: & InstructionStream>>interpretExtension:in:for: and the implementations of the selectors it sends in MethodContext and ContextPart. For a cogent but somewhat out-of-date account read the 4th part of Smalltalk-80: The Language and its Implementation on the wayback machine. Dwight Hughes digitised the last section of the blue book and put it up on his site, but its long gone and you'll have to find it on the wayback machine (if that still exists; I juts visited and got a 404).

The entire (I believe) Blue Book is available in PDF form here: http://stephane.ducasse.free.fr/FreeBooks/BlueBook/ Regards, -Martin

which has full text, so search for "Formal Specification of the Interpreter" on page 593
