When C++ Zero-Cost Abstraction fails: how-to Fix Your Compiler

Log in to save this to your schedule, view media, leave feedback and see who's attending!

This talk will present how a so-called C++ zero-cost abstraction can prevent an optimizing modern compiler to vectorize a trivial loop.
It will be used as a pretext to present some of Clang and LLVM internals, so that the root cause of this missing optimisation can be found, fixed and/or reported back to the
compiler developers.

The overall goal is to give more insight to C++ developers about what's going on with their compilers!
