Hi, I was able to figure out this one, by checking out profile.pl. However, I am still interested in getting to know if there is anyway to compile from bitcode to a normal executable? Maybe I am missing something obvious... :P ? Thanks Nipun On Fri, Apr 1, 2011 at 1:34 PM, Nipun Arora <nipun2512 at gmail.com> wrote: > Hi, > > Could anyone tell me how exactly can one convert a

Hi, Could anyone tell me how exactly can one convert a .bc file (bitcode file) to an executable in the native program. I was trying an instrumentation transform with the following workflow opt -insert-edge-profiling input.bc -o output.bc and then try and execute output.bc using lli output.bc however the program gives the following error : Program used external function

Hii, Thanks for the response, yes I couldn't find any way to extract the names through any of the passes. Where could I potentially insert a hack so that any function call to intrinsic functions or library functions can be retrieved? Could you gimme any ideas for the start? -Nipun On Fri, Jan 30, 2009 at 10:39 PM, Eli Friedman <eli.friedman at gmail.com>wrote: > On Fri, Jan 30,

Hi James, I will look into the RedHat newlib library, however, we def are looking for a solution for glibc, but maybe newlib would be a good way to go to test our complete workflow before putting an effort to generate control flow graphs for glibc. btw. I did have another question, hopefully you would be able to answer, what we are looking to do is to get the control flow graph including some

The names disappear in an unrecoverable way once

Hi Eli, Well I think a way to hack it might be better for my purposes, can you suggest any ways of getting started on that and where. Essentially I'm developing an IDE and need to extract the dependency graphs while retaining the actual function names rather than them being converted to llvm.* names. If I go for the other option you suggested. I'd have to do a one-to one mapping of all

I agree. Being a newbie myself, I can relate to what problems someone new to llvm would have.While I think most of the stuff I have tried will be useful, I wouldn't be entirely sure if its the best way to go about it.

Hi all, I am trying to do an analysis of a parallelized code using sse optimizations. The problem I am encountering is that I need to do some matching based on the analysis and I would like to extract the names of the functions as is rather than llvm intrinsics with an llvm. representation. Essentially I would like to extract the control flow graph representation with function names (eg.

Hey Devang, Thanks for the assist, I'm trying to extract a signature which uniquely identifies a block of code.... this is required for a project I am doing. The no of data structures is one of the identifying features of this signature.

Right now I am writing passes just to look for arrays & structs I am trying to identify the array by parsing the memory description(use regex's) ex./ { [20 x i8], i32 } *- for a struct. is a structure with a character array of size 20 and an integer. I'm not sure if llvm provides an easier way to do this? The type id for most arrays comes out to be a pointer rather than an array, its

How do you define a data structure for this purpose? Do you mean individual data types like structs or arrays? Or higher-level "logical" structures like lists, trees, or hash tables? The former is obviously easier but even the latter is possible, in some cases. --Vikram Associate Professor, Computer Science University of Illinois at Urbana-Champaign http://llvm.org/~vadve On

Hi, I am looking into something similar as well for auto-parallelization i.e. some sort of low level support at the IR level for parallelization. I'd be interested in collaborating with anyone who is working on the same. >From a brief look at the architectural overview of Polly, it seems as if the parallel code generation is being done at the IR level since the input file is an LLVM IR

Hi I was having just one more problem. I would like to find these datastructures/ primitive types etc inside a block, however the valuesymbol table is available only at a functional level. What can I do so as to get the number + type of datastructs(eg. arrays etc) inside a single block? Thanks Nipun On Fri, Oct 31, 2008 at 12:05 PM, Devang Patel <dpatel at apple.com> wrote: > Hi

Hi I am trying to count the no of datastructures and the type, say for example the number of arrays in a given code. Which pass would give me this info? And what do I need to use in it?

Hi, I read on the gentoo website http://en.gentoo-wiki.com/wiki/Llvm that glibc cannot be compiled using llvm because of some GNU extensions which LLVM does not support. Has there been any success in compiling glibc using LLVM so as to get the bytecode? We are looking to do whole program analysis to look at control flows including those in libc... we were hoping that we could get the control
