Hi All, I would like to have more details about this LLVM wished feature (taken from http://llvm.org/OpenProjects.html#misc_new): "Write a disassembler for machine code that would use TableGen to output MachineInstrs for transformations, optimizations, etc." The phrase refers to _native_ machine code? Any extra detail about this feature will be really appreciated, since I'm interested in implement this fea...

...uest/ I don't know about Tanu, but we can certainly use this in finding bugs in LLVM!

...ond. I am assuming native 32-bit binaries will run, just slower, so this is an "optimization". :) However, working on the interpreter is largely a waste of your time. The interpreter structure itself is due for a rewrite, see item #8 of http://llvm.cs.uiuc.edu/docs/OpenProjects.html#misc_new -- Misha Brukman :: http://misha.brukman.net :: http://llvm.cs.uiuc.edu

Tanu, You've seen ? :- http://www.st.cs.uni-sb.de/~lindig/src/quest/ Don't know whether it is applicable to what you are trying to achieve but I thought I should point it out in case it is useful to you and you have not seen it.

Hi, I noticed that LLVM had signed up as a mentoring organization for Google's summer of code. LLVM looks like an exciting project that overlaps some of my interests. I would be interested in developing an additional front end for a language it does not currently support (I'm open to what language). I do not know much about what this entails in regards to what LLVM requires from its

I would try that ..Thanks Another thing that I want to do is to randomize functions within a program (or file ), whatever is easier to do in llvm .Also please tell me how can I randomize global variables ?
