  70  * Architecture-specific ACPICA Subsystem Data Types
  71  *
  72  * The goal of these types is to provide source code portability across
  73  * 16-bit, 32-bit, and 64-bit targets.
  74  *
  75  * 1) The following types are of fixed size for all targets (16/32/64):
  76  *
  77  * BOOLEAN      Logical boolean
  78  *
  79  * UINT8        8-bit  (1 byte) unsigned value
  80  * UINT16       16-bit (2 byte) unsigned value
  81  * UINT32       32-bit (4 byte) unsigned value
  82  * UINT64       64-bit (8 byte) unsigned value
  83  *
  84  * INT16        16-bit (2 byte) signed value
  85  * INT32        32-bit (4 byte) signed value
  86  * INT64        64-bit (8 byte) signed value
  87  *
  88  * COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
  89  * compiler-dependent header(s) and were introduced because there is no common
  90  * 64-bit integer type across the various compilation models, as shown in
  91  * the table below.
  92  *
  93  * Datatype  LP64 ILP64 LLP64 ILP32 LP32 16bit
  94  * char      8    8     8     8     8    8
  95  * short     16   16    16    16    16   16
  96  * _int32         32
  97  * int       32   64    32    32    16   16
  98  * long      64   64    32    32    32   32
  99  * long long            64    64
 100  * pointer   64   64    64    32    32   32
 101  *
 102  * Note: ILP64 and LP32 are currently not supported.
 103  *
 104  *
 105  * 2) These types represent the native word size of the target mode of the
 106  * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
 107  * usually used for memory allocation, efficient loop counters, and array
 108  * indexes. The types are similar to the size_t type in the C library and are
 109  * required because there is no C type that consistently represents the native
 110  * data width.
 111  *
 112  * ACPI_SIZE        16/32/64-bit unsigned value
 113  * ACPI_NATIVE_UINT 16/32/64-bit unsigned value
 114  * ACPI_NATIVE_INT  16/32/64-bit signed value
