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