32 // New C++ Emitter!

34 // To use it just include the x86Emitter namespace into your file/class/function off choice.
35 //
36 // This header file is intended for use by public code. It includes the appropriate
37 // inlines and class definitions for efficient codegen. (code internal to the emitter
38 // should usually use ix86_internal.h instead, and manually include the
39 // ix86_inlines.inl file when it is known that inlining of ModSib functions are
40 // wanted).

50 // once most code is no longer dependent on them.

55 // CallAddress Macros -- An Optimization work-around hack!
56 // --------------------------------------------------------------------------------------
57 // MSVC 2008 fails to optimize direct invocation of static recompiled code buffers, instead
58 // insisting on "mov eax, immaddr; call eax". Likewise, GCC fails to optimize it also, unless
59 // the typecast is explicitly inlined. These macros account for these problems.
