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