//===-- include/Support/DataTypes.h - Define fixed size types ----*- C++ -*--=//
//
// This file contains definitions to figure out the size of _HOST_ data types.
// This file is important because different host OS's define different macros,
// which makes portability tough.  This file exports the following definitions:
//
//   LITTLE_ENDIAN: is #define'd if the host is little endian
//   int64_t      : is a typedef for the signed 64 bit system type
//   uint64_t     : is a typedef for the unsigned 64 bit system type
//   INT64_MAX    : is a #define specifying the max value for int64_t's
//
// No library is required when using these functinons.
//
//===----------------------------------------------------------------------===//

// TODO: This file sucks.  Not only does it not work, but this stuff should be
// autoconfiscated anyways. Major FIXME
