similar to: [LLVMdev] Strategy for leveraging llvm optimizations in vm

If you x86 assembly is sufficiently simple, I don't see any reason why you couldn't programmatically raise it back up to LLVM IR. People have tried this in the past (qemu, I think? I can't remember), and it usually results in some considerable slowdowns. I'd imagine that if your asm is sufficiently restricted, such as not needing to worry about arithmetic flags, the x87 FPU

CC'ing the mailing list. The inline assembly feature is described in the LLVM Language Reference Manual (http://llvm.org/docs/LangRef.html). I'm not really familiar with what the LLVM optimizers

Hi Everyone -- I'm planning on using LLVM to add some optimizing compiling capability to a Byte-Code driven virtual machine that is part of my foundation platform for a series of tool products I am building. I'm still pretty new to this whole arena and am in particular curious about one important aspect: It strikes me that the more optimizations applied to code (whether at the source

Hi Folks -- Let me go ahead and pose a question similar to the one Joachim poses below. I too am trying to evaluate whether LLVM will be of use to me in building a compiler and garbage collection mechanism for a byte code vm that I have built. Although there are multiple types of code that can be created with this system, all of them eventually translate to execution of one or more of these

Hi -- I'm wondering if some of you old hands might offer me some guidance. I've been working for some time with a virtual machine platform that is based loosely on the instruction set of a Forth hardware processor that Charles Moore designed sometime back. He used what he called a "MISC" or "Minimal Instruction Set Computer" and the original instruction set I was

I'm wondering if anyone is working on a machine code -> LLVM bitcode disassembler? Obviously, there won't be a one-to-one correspondence but it seems like you should be able to get close. There's always inline asm for the remaining fragments. So is there such a thing? Thank you, Bob

Sorry for the noise, but this is the message I meant to send to the list rather than replying to David directly. Unfortunately, I just sent his message to me before.

My answers are below at the end of your message.

Curious as to whether any work is in progress on this? Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20101202/0ae5d181/attachment.html>

Hi, I recently downloaded and installed the libcpu package (from http://libcpu.org ) that uses llvm as the backend on my linux machine. I have a piece of Motorola 88100 code (essentially the output of the 176.gcc benchmark from SPEC CPU 2000) that I am trying to run using this emulator, but I am running into errors when trying to run it. Has anyone been able to successfully use the m88k

What kinds of errors are you getting?

Hi, Here's one of my proposals for GSoC 2012. What do you think? Chip Project Title: Table-Driven Decompilation Abstract: Over the years, the LLVM family has grown to include nearly every type of build tool in existence. One of the few missing is a decompiler. LLVM's TableGen tool could potentially accelerate development of such a tool; most backends already have the information needed

Hi - Not sure if anyone else saw this or cares about a decompiler (not personally tested) https://github.com/draperlaboratory/fracture I wonder if they have been in contact with anyone in the community in getting this upstreamed. Does it look interesting to anyone else? (thoughts/random comments/feedback)

Hi, I want to convert x86 assembly source code to LLVM assembly language. How can I do this? If there is no direct solution would it be possible to implement one within the LLVM infrastructure with as less efforts as possible? I need someone to push me in a right direction. I've spent several days looking for a solution and still not found any. Thanks, Sergey -------------- next part

Does there exist a tool that could lift a binary (assembly for some supported target) to LLVM IR? If there isn't, does this seem like something that would be feasible? -------------- next part -------------- An HTML attachment was scrubbed...
