// Module Name:
//
// kxia64.h
//
// Abstract:
//
// This module contains the nongenerated part of the IA64 assembler
// header file. In general, it contains processor architecture constant
// information, however some assembler macros are also included.
//
// Author:
//
// bjl 12-Jun-95 (based on David N. Cutler (davec) 23-Mar-1990)
//
// Revision History:
//
//--
#define SHADOW_IRQL_IMPLEMENTATION 1
//
// N. B. Register aliases have been moved to ksia64.h (because we
// use assembler aliases not #define's)
//
// Register constants
// For setting non-rotating predicates (not used very much)
