So, let me rephrase, I understand what these functions are, I just want to know why and when they are inserted so that I can make an attempt to remove them, as they are not produced in llvm-gcc, only in clang?

Clang is inserting an llvm.memcpy function call into my program where it does not exist (the code never calls memcpy), is there a particular reason for this? It also looks like it's inserting two other artificial function calls, something to do with llvm.lifetime.start and llvm.lifetime.end, what are these functions and why are they being inserted artificially? Thanks. -------------- next
