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

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

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, 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

The generic rule is that R is not a macro language, so looping of names of things gets awkward. It is usually easier to use compound objects like lists and iterate over them. E.g. datanames <- paste0("aa_", 2000:2007) datalist <- lapply(datanames, get) names(datalist) <- datanames col1 <- lapply(datalist, "[[", 1) colnum <- lapply(col1, as.numeric) (The 2nd

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

Um, if you insist on doing it that way, at least use assign(varname, as.vector(get(varname))) -pd > On 4 Dec 2017, at 22:46 , Love Bohman <love.bohman at sociology.su.se> wrote: > > Hi! > Thanks for the replies! > I understand people more accustomed to R doesn't like looping much, and that thinking about loops is something I do since I worked with Stata a lot.

Hello, I am trying to create a call to a function which returns a struct in llvm pass. I also want to read struct fields returned from this function call. Can somebody help me with this? Regards, Sangeeta

`-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/ >

Hi! Thanks for the replies! I understand people more accustomed to R doesn't like looping much, and that thinking about loops is something I do since I worked with Stata a lot. The syntax from Peter Dalgaard was really clever, and I learned a lot from it, even though it didn't solve my problem (I guess it wasn't very well explained). My problem was basically that I have a data matrix

Loops are not evil, and no-one in this thread said they are. But I believe your failure to provide a reproducible example is creating confusion, since you may be using words that mean one thing to you and something else to the readers here. ################################ # A reproducible example includes a tiny set of sample data # Since we cannot reproducibly refer to filenames (your
