Initialization

There was a CPP Con talk some years back about exactly this work by Microsoft. Basically let us teach the compiler to zero initialize everything, then run tests to see how awful the results are, teach the compiler to optimize away these dead stores and/or perform zero initialization that it more easily recognises as dead stores, iterate. IIRC The first few loops are very, very bad, nothing you could possibly ship, but as they learn what they're doing by the end they can more or less do this over the bulk of the system and get the same performance as before but with more confidence there aren't scary initialisation bugs. Obviously they were in C++ and their own C++ compiler, where Linux would want C and GCC, but it's not so different otherwise. If people can't find it themselves I can search Youtube maybe.
