similar to: [LLVMdev] Advice - llvm as binary to binary translator ?

Hi Eric, I'm currently writing an IA-32 to LLVMIR translator. I'm only mid way through, but I can certainly say that there have been more difficulties than I anticipated when I began! I think that it is a reasonable approach, perhaps especially in your case, since you have an emulator already. Automatic static translation is equivalent to the halting problem for IA-32 code, though

I went ahead and tried to translate my legacy machine language into IR. Legacy branch instructions have me stumped. The branch instructions are already resolved to destination addresses in the legacy machine code. For example, there is an instruction that performs an unconditional branch to the address stored in legacy register B1. I can represent register B1 as a local variable: %B1

Hello List, I am a newbie regarding LLVM and need some information on LLVM. I am working on dynamic binary translation and I am looking into if LLVM can be used for the purpose. The goal here is to generate highly optimized translated (host) code from target code. I have following questions. 1. Can LLVM be used in a dynamic binary translator? Dynamic translator translators target code for an

There has been some discussion about this within the past two months on this list, IIRC. You should try searching the archives for that discussion.

Hello, > 1. Can LLVM be used in a dynamic binary translator? Dynamic translator translators target code for an architecture (say PPC) to host code (say x86) and execute it. Yes, see llvm-qemu project (2007 GSoC). > 2. Can LLVM understand disassembled target code and generate optimized host code? No, it's not a job of LLVM. You have to convert binary code for your platform into LLVM IR

Hi, (Redirect me to a more appropriate mailing list if need be) For a class project, I intend to write a binary translator for Qemu using LLVM. My plan (still forming) is to implement a frontend that will convert DEC Alpha instructions into LLVM IR which can then be optimized and run through whatever backends LLVM has to arrive at optimized native code. This was done as a GSoC project in 2007

Hello, here's my proposal for a GSoC project with LLVM. I'm happy for any feedback or advice you can give me. Thanks in Advance Tilmann * Proposal for Google Summer of Code Project ** Using LLVM as a backend for QEMU's dynamic binary translation *** Abstract: The goal of this project is to modify the QEMU dynamic binary translator to use components of the LLVM compiler

Thank you very much for the feedback, I tried to address the brought up issues in this updated proposal. In case you have any suggestions or comments feel free to tell me. Thanks in Advance Tilmann * Proposal for Google Summer of Code Project ** Using LLVM as a backend for QEMU's dynamic binary translation *** Terms: - host architecture: the architecture of the CPU QEMU is running on

Hi, As told in "Control Groups Resource Management" libvirt page : Legacy cgroups layout Prior to libvirt 1.0.5, the cgroups layout created by libvirt was different from that described above, and did not allow for administrator customization. Libvirt used a fixed, 3-level hierarchy libvirt/{qemu,lxc}/$VMNAME which was rooted at the point in the hierarchy where libvirtd itself was

Sure, sorry about that -- FYI, the "Maintained By" link goes to your email, so you might want to change that.

I'm happy to say that LLVM has 6 projects approved for Google SoC this year (3x more than last year!): [vmkit] "Generics support for N3" by Tilmann Schelle [clang] "Adding support for C++ classes in clang" by Argiris Kirtzidis [codegen] "PSP (Playstation Portable) support into LLVM Mips backend" by Bruno Cardoso Lopes [llvmir]

Hi, In OpenCL, the "barrier()" function, as well as various target specific memory fence intrinsics, should prevent loads/stores of the relevant address space from being moved across them. Kernel pointers with "restrict" attributes are implemented by marking the pointer "noalias" in the LLVMIR. However, in LLVM, "noalias" pointers are not affected by llvm

Hi, Just installed 0.9.4 (from 0.8 series) and ran the spec translator. It messed up specs that had the should include() where the argument to include is a string (using no parens for the arg) IOW, given: context "OldSchool" do class OldSchool attr_accessor collection def initialize @collection = [] end def add_new(item)

Does the stable version of GlusterFS, GlusterFS 1.3-SUSKE RELEASE, have the High Availably (HA) Translator or is it just in v1.4? John This email was independently scanned for viruses by McAfee anti-virus software and none were found

For every level of translation [in terms of "human readable -> machine code translation", not someone translating a literary work from one language to another - although often some subtle details are lost here too], a little bit of the semantic meaning is lost. This means that you can almost never completely reconstruct the code in original form from the machine-code, or the C-code
