https://issues.dlang.org/show_bug.cgi?id=19575 Issue ID: 19575 Summary: core.cpuid not usable without a runtime Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: blocker Priority: P1 Component: druntime Assignee: nobody puremagic.com Reporter: aliloko gmail.com core.cpuid relias on static shared this() for initialization. Without a D runtime, such initializers are never called. So we had to duplicate core.cpuid. It goes further, as rounding mode in Phobos uses the runtime variable `sse` from `core.cpuid`. Again, this makes FloatingPointControl not usable Why do I need `FloatingPointControl` in -betterC? I'm implementing intel-intrinsics for both DMD and LDC, and the slow compatible path has to have the same rounding-mode. But `intel-intrinsics` package is intended to work in any situation, with or without runtime. ***The only thing needed is a way to initialized core.cpuid with a function call.*** --
