33 // This header module contains functions which, under most circumstances, inline
34 // nicely with constant propagation from the compiler, resulting in little or
35 // no actual codegen in the majority of emitter statements. (common forms include:
36 // RegToReg, PointerToReg, RegToPointer). These cannot be included in the class
37 // definitions in the .h file because of inter-dependencies with other classes.
38 // (score one for C++!!)
39 //
40 // In order for MSVC to work correctly with __forceinline on class members,
41 // however, we need to include these methods into all source files which might
42 // reference them. Without this MSVC generates linker errors. Or, in other words,
43 // global optimization fails to resolve the externals and junk.
44 // (score one for MSVC!)
