search for: getnumuses

Hi all, I am doing a project that requires counting the number of uses of a value only in all dominated blocks in a function. I checked the manual for llvm::User class, but only get this unsigned <http://llvm.org/test-doxygen/api/classunsigned.html> getNumUses <http://llvm.org/test-doxygen/api/classllvm_1_1Value.html#a380559e99b47632a34f74de7c1d03cc0> () const This gives me all the uses of a value. Is there any simple way, like an API to do this? Or I have to manually write a method to traverse dominated basic blocks and count the number of uses?...

Maybe nicer.. auto i = Src->uses().begin(); std::advance(i, Src->getNumUses() - 1); i->getUser()->dump(); 2018-04-20 19:19 GMT+02:00 Dávid Bolvanský <david.bolvansky at gmail.com>: > Use *last = nullptr; > for (Use &U : Src->uses()) > last = &U; > last->getUser()->dump(); > > > Or any better solution? > &gt...

Use *last = nullptr; for (Use &U : Src->uses()) last = &U; last->getUser()->dump(); Or any better solution? 2018-04-20 19:19 GMT+02:00 Dávid Bolvanský <david.bolvansky at gmail.com>: > Is: > > > 2018-04-20 18:07 GMT+02:00 Dávid Bolvanský <david.bolvansky at gmail.com>: > >> Hello, >> >> Code: https://godbolt.org/g/EG4Wi6

...the use list, which probably invalidated the use_iterator and caused my code to miss some of the uses. The following works great! (I'll spare you the details about what I am actually trying to do here, unless you really want to know more.)
