Teja, I just checked my version of llc to make sure it worked on arm and x86_64 respectively. The website llvm.org hosts a manual page for this tool at http://llvm.org/docs/CommandGuide/llc.html. I think this tool from the ample LLVM armory will accomplish what you are looking to do. All the best in your endeavors, Shaun Shaun Hubbard On Mar 7, 2013, at 10:39 PM, teja tamboli

Hi All, I am working on writing pass in LLVM and interested in doing function permutation at intermediate representation byte code level? If I have lets say C program having three functions and its corresponding IR bytecode. void findLen(char a[10]) { int tmp = strlen(a); printf("Len is : %d\n", tmp); } void muladd(int a, int b, int c) { int tmp = a + b; int tmp1 = tmp *

Hello, I am looking for tool to convert file from either (.s) bytecode or (.bc) bitcode to .asm file. Basically assembly instruction file for my x86 backend. I think so we can use llvm-objdump. However I am not able to figure out its exact options. Could you please tell me how to do that? -- Thanks, Teja -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi Duncan, I mean both. In order to generate random code, I have to add function definitions and also for robustness I have to call these functions from already existing functions. So, have to add calling type of instructions also in the existing function. In future I also have to change instructions for simple substitution meaning 'add a, b' can be done using 'sub a, 0' and

Teja, Your mention of .s being bytecode confuses me, but if you're asking how to lower a bitcode (.bc) or IR file (.ll) to assembly (.s) than llc is the tool you are looking for. llc -O2 path/to/bitcode/input.bc -o output.s -Chris On Mar 7, 2013, at 10:39 PM, teja tamboli wrote: > Hello, > > I am looking for tool to convert file from either (.s) bytecode or (.bc) bitcode to

Hi all, I am working on my Master's project in security and I am trying to iterate over the argument list of the function. Basically I need to do following things : 1. Check data type of each argument of the argument list of the function. 2. Based on its data type like character array or integer array, pointer, int, char, take different action. 3. I have added following code to check its

Hi John and All, Thank you for the your inputs,we tried running Safecode with Liblto on our code base few weeks back,I'm very sorry to say this that we feel that safecode is not so stable and output is not so informative ,Please correct us if i'm wrong here. Thanks Again. ~Umesh On May 25, 2012 7:54 PM, "John Criswell" <criswell at illinois.edu> wrote: > On

Dear John, Thanks for your reply. I want to do whole program analysis, all what I need are just the separate .bc files. What instructions should I follow? I run the configure on apache in this way: CC=clang CFLAGS=-emit-llvm ./configure while I get the error message like: checking for gcc... clang checking for C compiler default output file name... configure: error: C compiler cannot

Hello, Is the SVA codebase publically available, and if so, where can I find it? Thanks. -- gregory malecha -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20110627/4f816aa6/attachment.html>

Hi, How to compile a large project (such as Apache) by using llvm-gcc? I tried to replace CC with llvm-gcc and CFLAGS with -emit-llvm while running configure, but it didn't work. Thank you for your help. -Wink

Whole-program analysis requires that you link all of the individual bitcode files from different compilation unit (i.e., individual .c files) together into a single

Hello all, I'm a research assistant at the University of Wisconsin and we're trying to come up with a general way to run our whole program analysis over programs that may use different methods to perform the build. I saw some discussion that liblto could be used for this (and safecode successfully did it) for llvm 2.6 - 3.0, but that doesn't seem to be working the same way with llvm

Thanks John. Your approach worked fine for my small toy program. Now, I would like to run my module pass on a huge project (still a single executable) consisting of a few thousand bit code files scattered in many different directories. And some of them are static libraries. Do you still think it's a good idea to manually gather and link them with llvm-ld? I've seen other module pass

If, however, you want to do inter-procedural optimization or whole

I had actually started out with a project infrastructure, then switched to a pass implementation alone, not realizing I could combine the two. I've now reverted back to my old project,

Hi All , I'm not sure the question is relevant to the forum,My apologies if not We are trying to instrument our code with ASan(Clang) to find the memory errors and we see that the application execution halts when the Asan check finds the memory issue at the being. Which mean we need to fix the issue then compile and execute the instrumented code again to find the next issue and so on
