Bytecode lib

#1

I started writing a bytecode library but you all know how long I stick to a project before deleting it

It will be based on the mocha decompiler which largely still works, the only problems I have seen so far are the synchronised blocks and string append replacer. Mocha is nice apart from a few small things, such as it being old and not abstracting constant push instructions nicely (uses string values or constant pool indices)

I plan to rewrite it from the ground up incorporating extra features including but not unlimited to; generation of bytecode as well as source from IR code, more suitable abstractions, an application/library representation encapsulating type hierarchies and ideally some sort of pattern matching/transforming script system

I will also keep the constantpool because it simplifies type validation and will contribute to an application wide symbol table, I will not however provide an interface for searching it because that is fucking retarded

Where’s semaphore? It’d be good if he chimed in here on the importance of not pissing time away by reinventing the wheel. =\

#3

It isnt reinventing the wheel, more reengineering it. The mocha source code (as far as I know) is not available and I have already refactored much of it.

I would however love to obtain crema just to see what it did and how

edit:
in other news, if somebody that isnt a fuckhead and has any experience with compilers wants to help correct/complete my refactor, feel free to offer

#4

Is it written in Delphi?

#5

Freddy just facepalmed and is thinking about locking this thread

#6

There’s nothing wrong with this topic. =\ I still don’t see why frank_ can’t make do with bcel or asm though. :stuck_out_tongue:

#7

frank_ is a hardass mother fucker asm and bcel are too easy he needs a real challenge

#8

Anyone who buys delphi is being taken for a ride. They’re being sold bottled water straight from the tap.

#10

(pseudo?) open source?

It’s also like selling sand to people who live in the desert! Consequently, one of the runescape npcs allegedly managed to do this!

I get the feeling that frank_ won’t share. :stuck_out_tongue:

#12

please stop derailing my thread by mentioning freddy

ideally it would be closed source, but depending on how things work out it would potentially become open source

edit: it will be implemented in java of course

I see you replyizzled to my post - thank you. Open sourcing it would be pretty cool and useful.

#14

For the purposes of this section, providing a jar file with the request not to post elsewhere would be open source enough for most.

#15

considering this the the general discussion of the community members section, I disagree

#16

Fuck land, I’m on a boat motherfucker.
Fuck trees, I climb buoys motherfucker.
I’m on the deck with my boys motherfucker.
The boat engine make noise motherfucker.

#17

I wouldn’t blame him.

How is the API structured?

#18

[quote=“c|p, post:17, topic:335796”]How is the API structured?[/quote]I’m not completely decided on that yet

I will provide access to the low level IR, the unstructured high level IR and then the structured high level IR

I also intend to provide a “pattern matching” scripting system to aid the replacement of code patterns, potentially accessible on all levels of the IR

#19

identified genetic codons pls
makes it pro

good idea though, rep ++
