...lo, I would like to find out a detail about intrinsics functions. When I use memset form a standard library it is always converted to llvm's memset, however the usage of some others as sqrt, pow, sin do not lead to the same. How can I get the same effect? Why there is no overall LLVM pass like IntrinsicLowerinPass.cpp (it has only some specific ones)? There is only a function that does this. -------------- next part -------------- An HTML attachment was scrubbed...
