//===-- 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:
|
|
//
|
|
// ENDIAN_LITTLE : 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.
|
