1 //===-- include/Support/DataTypes.h - Define fixed size types ----*- C++ -*--=//
3 // This file contains definitions to figure out the size of _HOST_ data types.
4 // This file is important because different host OS's define different macros,
5 // which makes portability tough. This file exports the following definitions:
7 // LITTLE_ENDIAN: is #define'd if the host is little endian
8 // int64_t : is a typedef for the signed 64 bit system type
9 // uint64_t : is a typedef for the unsigned 64 bit system type
11 // No library is required when using these functinons.
13 //===----------------------------------------------------------------------===//
15 // TODO: This file sucks. Not only does it not work, but this stuff should be
16 // autoconfiscated anyways. Major FIXME
