Hi all, Clang-folks are working on an option to automatically initialize local variables, similar to what D does. (only local variables, not heap allocated variables) Read this thread if you are interested in performance measurements and discussion about perf impact (currently about 1%) and compiler improvements to try to mitigate it: https://lists.llvm.org/pipermail/cfe-dev/2019-January/060878.html ("zero-init" = initialize with all zeros, "pattern-init" = initialize with a specific bit pattern) -Johan |
