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 line argument '-rdetector’.” > > Although same option work with...

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

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...

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

Hello All, I am instrumenting IR to pass addres of the function to runtime but I am getting error - Instruction does not dominate all uses.

`-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/ > questions/29910051/integrating-llvm-passes/48142693#48142693, to > integrate my pass with pass manager and run it with clang.

Why the output is different for this below program when compiled using clang with fast-math optimization #include<stdio.h> int main() { double d = 1.0; double max = 1.79769e+308; d /= max; printf("d:%e:\n", d); d *= max; printf("d:%e:\n", d); return 0; } prints 0 with fast math but 1 without fast math. -------------- next part -------------- An
