| 70 | * Packing directives : These are used to force compiler to pack bits and |
| 71 | * bytes in the data structure. C standard does not regulate this strictly, |
| 72 | * and many things are to compiler implementation. Many compilers support |
| 73 | * compiler specific directives or options that allow different packing |
| 74 | * and alignment. |
| 75 | * |
| 76 | * Alignment directives : Compiler may think packed data structures have |
| 77 | * no specific alignment requirement. Then compiler may generate multiple |
| 78 | * byte accesses to access two byte or four bytes data structures. This |
| 79 | * affects on performance especially for RISC systems. If some data |
| 80 | * structure is located on specific alignment always, alignment directives |
| 81 | * help compiler generate more efficient codes. |
