Hi, I am running a basic block pass (and iterating through each instruction). Is it possible to convert the basic block instruction form llvm IR to x86 IRWITHIN the path ?

...instruction). Is it possible to convert the basic block instruction form llvm IR to x86 IRWITHIN the path ? I mean: is LLVM API exists for this purpose ? Again, thanks.

Hi, I am new in the "Linux business" and i need to add an optimization to the LLVM compiler. I would like to know what is the bast way to debug (IDE) the LLVM compiler ? To be more precise, what is the equivalent to Microsoft visual studio on Linux platform? is it eclipse? I want features like: syntax highlight, go to def, etc. Thanks. -------------- next part -------------- An HTML

...ill start with that i am vary grateful for your time.And continue with, i am sorry if my Qs aren't quite accurate( i just started with the LLVM compiler).

...livein/liveout information. It's intended to be used as a heuristic.

Hi, I am a student (software engineering), and i am using the LLVM in my project (I am sorry of the lack of details, but i want to take the minimum of your time, if you want more details don't hesitate...). I need to add a new optimization to the LLVM compiler. The optimization ALREADY written for x86 IR (i mean that the code that handles the optimization is designated to work on assembly 86)

Thank you. Is it possible to determine the liveout of the operands (see example bellow) ? %5 = add i32 %4, %3 For '%5': i can simply use " i->isUsedOutsideOfBlock() " For '%3' and '%4' : this is the question ... >From your answer, is it possible to determine *which* value is liveout ( in binary instruction)?

...s Eclipse though. I don't know if anybody has done the configuration files for LLVM-GCC on those IDEs yet but it should definitely be possible to modify from the standard GCC profiles. If you find something better, let us know. --Sam ________________________________ From: Rotem Varon <varonrotem at gmail.com> To: LLVM Developers Mailing List <llvmdev at cs.uiuc.edu> Sent: Monday, May 18, 2009 3:26:44 PM Subject: [LLVMdev] IDE for llvm Hi, I am new in the "Linux business" and i need to add an optimization to the LLVM compiler.

Hi, I am writing a new transformation (Basic block pass). In the "\llvm-2.5\lib\VMCore\AsmWriter.cpp " file there are some of function i want to use. What do i need to add to the transformation code, so i will be able to use those functions? I tried to use a function and got this error : 'AssemblyWriter' was not declared in this scope.

Hi, I am trying to set loop unrolling as a required pass. AU.addRequired<LoopUnroll>(); should I include any header file? How can I be possessive that "LoopUnroll" is the name I need ?

Hi, How can i know, if a value have uses outside of the current basic block (liveout), without iterating through all the basic block ?

Hi, Let say i am writing a code inside basic block pass and iterating all the instructions inside, and i encountered in this instruction : %3 = add i32 %1, 2 I want to convert this instruction to something like this: add R1, 2, R3 I know the opocode, but i what i need is, the operands %1 and 2 (in this example). I will be grateful if some one will tell me how to do so . -------------- next
