search for: _parallel

Thanks Mehdi. My pass clones the functions within a module in order to have the original function and an exact copy of the same function but with a different name, i.e. sum() and sum_parallel(). After my pass I will run ThreadSanitizer instrumentation pass only on the new copy of the functions, i.e. only the “_parallel” functions will be instrumented by tsan. In some programs that I am compiling, the functions such as atoi and atof get cloned but I want to avoid this, and I noticed tha...

Because what is happening is that if function “atoi” gets cloned I don’t have a definition of “atoi_parallel” therefore I get undefined references when linking. I just want to clone and instrument functions implemented in modules of my program. > On Nov 19, 2016, at 13:54, Mehdi Amini <mehdi.amini at apple.com> wrote: > > >> On Nov 19, 2016, at 12:44 PM, Simone Atzeni <simone.at...

But you can also run the eliminate_available_externally pass before performing your transformation. No I am not updating call sites, I want the body of the f...

Hi, could anybody explain what GlobalValue::AvailableExternallyLinkage means? I implemented an instrumentation pass that creates a clone of a function. For some programs I noticed that also function such as “atoi”, “atof”, “__strspn_c2”, etc. they get cloned even if I am not implementing them in the module. I would like to avoid cloning those functions, so I noticed that they have
