// To use it just include the x86Emitter namespace into your file/class/function off choice.

//
|
|
// This header file is intended for use by public code. It includes the appropriate
|
|
// inlines and class definitions for efficient codegen. (code internal to the emitter
|
|
// should usually use ix86_internal.h instead, and manually include the
|
|
// ix86_inlines.inl file when it is known that inlining of ModSib functions are
|
|
// wanted).

// MSVC 2008 fails to optimize direct invocation of static recompiled code buffers, instead
|
|
// insisting on "mov eax, immaddr; call eax". Likewise, GCC fails to optimize it also, unless
|
|
// the typecast is explicitly inlined. These macros account for these problems.
