similar to: llvm dynamic execution trace

Hi Dean, thank you for the response! I'm a newbie to LLVM, a student working on an LLVM project so I'm not quite sure of what you're suggesting, please excuse my naivety. To clarify there used to exist this http://llvm.org/releases/1.0/docs/CommandGuide/lli.html where you could type "lli -trace 'filename.bc' and you would get a dump of the dynamic excutiion trace. I

Hi John, Thank you so much for the valuable answer! :) However, i have one tough issue that i need to solve, in my pass : let's say here %s = add %a, %b I need to check if the value of %a or %b is 2 or 4 and then apply a transformation to the other operand accordingly, for example if the value of %a = 2 the i'll multiply %b by 2 in my transform pass. I'm having a hard time

hey john, yes indeed, that's what I'm trying, retreiving the values of %a and %b in an LLVM pass, sorry about the confusion.

Hi Everyone, I asked a question on the dev list related to the topic to which John Criswell and Jeremy Lakeman kindly provided some valuable insight. I'm still stuck on the issue and i'm hoping i didn't phrase the question well enough. I have a *foo.c* file that is : *#include <stdio.h>* *int foo(int a, int b){* * return a+b;* *}* *int main() {* *int x=foo(3,1); *

Hello Everyone, I need some help in retrieving the numeric value of an instruction operand from LLVM IR. this is what the IR looks like for a simple add function that adds two i32 integers define i32 @summ(i32 %a, i32 %b) #0 { entry: %add = add nsw i32 %b, %a ret i32 %add } i would like to know the integer value of %a and %b. I've tried -i->getOpcodeName() which gives me the

That source file was removed from LLVM in r232397 on March 16, 2015. It looks like lljvm hasn't been updated in a long time. LLVM's C++ APIs are not stable, so there is no expectation that a project built against LLVM's C++ API in 2015 would build or reasonably function against LLVM trunk. The project probably works against LLVM 3.6.2 which was (I believe) the last LLVM release to

Hi fellow devs, I was looking for converting LLVM IR to JavaBytecode by using lljvm project of https://github.com/davidar/lljvm They don't seem to compile, once i run *make* in the root directory it give me the error : cd include && make all make[1]: Entering directory `/home/rtiwari1/llvm_new/lljvm/include' make[1]: Nothing to be done for `all'. make[1]: Leaving

## TL;DR We introduce bcov, an open-source binary-level coverage analysis tool [1]. The details are discussed in our paper [2], which is accepted to ESEC/FSE'20. bcov statically instruments x86-64 ELF binaries without compiler support. It features several techniques that allow it to achieve high performance, transparency, and flexibility. For example, running "make

Hi All, I have successfully configure the PXE and its working fine, the problem is that after timeout in the following msg Automatic boot in # second the screen stuck/hang there showing the above message or the menu if we choose to selection from menu until image is loaded from network.

Hi All, Whenever an EXT3 partition is created some space is reserved for super-user, I used the mkfs.ext3 with option -m set to 0, but there is no effect it still reserve the space. How can i set the reserved-space to 0 or calculate the reserved-space in advance? Any suggestion/idea? Regards, -------------- next part -------------- An HTML attachment was scrubbed... URL:

TL;DR: At Google we use a call tracing system called XRay which inserts patchable instrumentation points into function entries and exits. If the community is interested, we'd like to contribute this system to the LLVM project. Many more details are contained in the whitepaper at: https://storage.googleapis.com/xray-downloads/whitepaper/XRayAFunctionCallTracingSystem.pdf Who's

Hi everyone, I'm struggling on a module pass, my goal is to change the number of arguments of a function found in the IR( the first function found). My approach is using a modulepass ,creating a function with exactly one argument then cloning the first found function using *CloneFunctionInto*; then i replace uses of the old function using *Old_func->replaceAllUsesWith(new_Func)*. I have

Hi fellow devs, I was looking for a way to run C on the JVM and i found LLJVM which apparently does exactly that! Howevere,unfortunately it seems dead on the main david's git https://github.com/davidar/lljvm as well as the slightly newer one https://github.com/hyc/lljvm. They don't seem to compile, once i run make in the root directory it give me the error : " *In file included

Hello Trevor, I wonder how I can find out for sure what is the H/W version for a PROSODY ACULAB SS7 Card? I dought that I have a ver 1.1 which have may issues with recently made computers. I have a case opened for my problem with aculab but sysdiag shows that I have ver 1.1 and aculab says I have ver1.5! can sysdiag be inaccurate? I tried config summary and I had the same result! wish you

By any chance is any one aware of a website, book, paper, etc. or combinations of those sources that show plots of different distributions? After reading a pretty good whitepaper I became aware of the benefit of I the benefit of doing Q-Q plots and histograms to help assess a distribution.   The whitepaper is called: "Univariate Analysis and Normality Test Using SAS, Stata, and SPSS*" ,

Attached is a 500KB read-only .doc file with a Samba and Terminal Server whitepaper. I have tried to hit every known issue and all available workarounds. If anyone has comments or suggestions, let me know. JT has it, so it should end up in the next How-To. Sorry about the file format, but the .pdf was 2.5MB, which I thought was too big to post.

Hi all, Im new to shorewell, can anyone guide me whether I can use shorewell for my work.
