#pragma once

// This header module contains functions which, under most circumstances, inline
// nicely with constant propagation from the compiler, resulting in little or
// no actual codegen in the majority of emitter statements. (common forms include:
// RegToReg, PointerToReg, RegToPointer).  These cannot be included in the class
// definitions in the .h file because of inter-dependencies with other classes.
//   (score one for C++!!)
//
// In order for MSVC to work correctly with __forceinline on class members,
// however, we need to include these methods into all source files which might
// reference them.  Without this MSVC generates linker errors.  Or, in other words,
// global optimization fails to resolve the externals and junk.
//   (score one for MSVC!)
