Bob Moore | defba1d | 2005-12-16 17:05:00 -0500 | [diff] [blame] | 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 |
