Re: 4x faster strlen with 4 char sentinel

On Monday, 27 June 2016 at 16:22:56 UTC, Jay Norwood wrote: This strlen2 doesn't require special alignment or casting of char pointer types to some larger type. That keeps the strlen2 implementation fairly simple. Yes, and the idea of speeding up strings by padding out with zeros is not new.

Logical location of template instantiations

import std.conv, core.memory; struct S { int x; private this(int val) { x = val; } } void main() { auto ptr = cast(S*)GC.malloc(S.sizeof); auto s = ptr.emplace(3); } This code does not work, as the call `ptr.emplace(3)` creates a
