similar to: Avoiding functions in dynamic library

Hello Everyone, Is there any way in llvm by which I can avoid functions defined in dynamic library in my llvm function pass. I am interested in functions defined only in application, not in the dynamic library. One way is to add functions name in a file and iterate over only those functions but its very cumbersome as my application consists of many mangled functions. Any help would be much

(though, usual caveat: you /usually/ shouldn't be doing that - instead relying only on whatever semantics the IR actually carries, rather than implying extra semantics based on the demangled name) On Wed, Jun 24, 2020 at 12:48 PM Johannes Doerfert via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > I have not tried it but maybe > > `std::string llvm::demangle(const

Hello, I am doing some program analysis with C++ programs. I need to check if some particular function is called in the program, for that I need the name of the function being called in the call instruction. Since C++ mangles the name of the function, I need a way to demangle the function name in llvm IR. Is there any way to achieve that in llvm pass? Regards, Sangeeta -------------- next part

Do you pull clang under llvm/tools and compile it as well? In theory, if `opt` recognize the option, so does `clang -mllvm`. 2018-01-12 8:47 GMT+08:00 sangeeta chowdhary <sangitachowdhary at gmail.com>: > Hello, > > I have tried giving this option like this > > clang -c -emit-llvm -mllvm -rdetector hello.c -c -o hello.bc > but I am getting error " Unknown command

I am sorry to not make my question clear. My question is how this value is calculated without having fadd and fsub in IR?

Hello, I am working on creating a llvm pass which clones a certain function with a different name using CloneFunctionInto. I create a call instruction to call a new cloned function from the old function. In llvm IR and in .s file everything looks as expected, but when I call this program with gdb and set a breakpoint on this new function, gdb shows the name of the original function. I know it has

Hello, LLVM IR flattens out the structure with one integer element to i32. Is there any way to disable this? I want to preserve the type information of the structure. I tried compiling the program with O0, it maintains the type for most of the instructions but for all. Regards, Sangeeta -------------- next part -------------- An HTML attachment was scrubbed...

This is of course not homework. I am trying to understand how fast math optimizations work in llvm. When I compared IR for both the programs, the only thing I have noticed is that fdiv and fmul are replaced with fdiv fast and fmul fast. Not sure what happens in fdiv fast and fmul fast. I feel that its because d/max is really small number and fast-math does not care about small numbers and consider

Hello, I have followed steps given in - https://stackoverflow.com/questions/29910051/integrating-llvm-passes/48142693#48142693 <https://stackoverflow.com/questions/29910051/integrating-llvm-passes/48142693#48142693>, to integrate my pass with pass manager and run it with clang. I am able to run my pass with opt - opt -mypass but when I try to run it with clang, I always get an error -

Clang doesn’t support adding passes from the command line the way opt does. Opt has special parsing in opt.cpp for this that clang doesn’t have. I’m not sure what the correct way to do this is. I think your plugin needs to do something to tell clang/llvm when to run the pass. I’ll try to look later when I’m back at a computer. On Fri, Jan 12, 2018 at 7:00 PM 陳韋任 via llvm-dev <llvm-dev at

Hi, I have below code in C - int main() { double x,y; x = 1e16; y = (x + 1) - x; printf("y:%e\n", y); return 0; } llvm bitcode looks like this for this function - ; Function Attrs: nounwind uwtable define dso_local i32 @main() local_unnamed_addr #0 { entry: %call = tail call i32 (i8*, ...) @printf(i8* getelementptr inbounds ([4 x i8], [4 x i8]* @.str, i64 0, i64

`-mypass` should be only recognize by the backend part (i.e. llvm). You should add `-mllvm` to tell clang the following argument have to be passed to the backend part. 2018-01-08 8:02 GMT+08:00 sangeeta chowdhary via llvm-dev < llvm-dev at lists.llvm.org>: > Hello, > > I have followed steps given in - https://stackoverflow.com/ >

Steps to do gluster clean up 1. umount -f /export/home/ecmsftp 2. Remove the /export/home/ecmsftp mount point line from /etc/fstab file if it exists. 3. Delete gluster file system volume if it exists; ignore if it does not exist. # gluster gluster>volume list eftpVol gluster> volume stop eftpVol Stopping volume will make its data inaccessible.

Hi, I am wondering whether some of you have a pointer to an alternative. I am currently writing my thesis in Latex (several documents), well grown over time, I am sure many of you are familiar with the situation. Likewise I am doing the quantitative analysis with R, and again a lot of lines of more or less wellwritten code. The outputs are graphs (which one can wonderfully integrate as PNG objects

Hello everyone, I've noticed something odd with SWAT version 3.0 and above. Specifically, for fields such as "read list" and "write list", any spaces in group names are replaced with a comma and a space when changes are committed via SWAT. For all previous versions of SWAT I've been able to use group names with spaces without this mangling from SWAT. At first I

Hello All, I am trying to write llvm pass to instrument function in external library. I am using clang to automatically load my pass. I have test.cpp which calls functions in library testlib.so. I have written llvm pass to instrument all reads and writes in test.cpp and call function(recordRW) in testlib.so. this is how my pass looks like - for (auto &BB : F) { for (auto &I : BB)
