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

Retrieving numeric value of instruction operand
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

Writing a pass to retrieve instruction operand value
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); *

Retrieving numeric value of instruction operand
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

LLJVM make error
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

Introducing the binary-level coverage analysis tool bcov
## 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

Writing Module Pass to modify arguments of a function
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

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.
