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
