2 | * Genevent |
3 | * |
4 | * Event generator. XML to logging C code converter. |
5 | * |
6 | * Program parameters : |
7 | * ./genevent name.xml |
8 | * |
9 | * Will generate ltt-facility-name.h, ltt-facility-id-name.h |
10 | * ltt-facility-loader-name.c, ltt-facility-loader-name.h |
11 | * in the current directory. |
12 | * |
13 | * Supports : |
14 | * - C Alignment |
15 | * - C types : struct, union, enum, basic types. |
16 | * - Architectures : LP32, ILP32, ILP64, LLP64, LP64. |
17 | * |
18 | * Additionnal structures supported : |
19 | * - embedded variable size strings |
20 | * - embedded variable size arrays |
21 | * - embedded variable size sequences |
22 | * |
23 | * Notes : |
24 | * (1) |
25 | * enums are limited to integer type, as this is what is used in C. Note, |
26 | * however, that ISO/IEC 9899:TC2 specify that the type of enum can be char, |
27 | * unsigned int or int. This is implementation defined (compiler). That's why we |
28 | * add a check for sizeof enum. |
29 | * |
30 | * (2) |
31 | * Because of archtecture defined type sizes, we need to ask for ltt_align |
32 | * (which gives the alignment) by passing basic types, not their actual sizes. |
33 | * It's up to ltt_align to determine sizes of types. |
34 | * |
35 | * Note that, from |
36 | * http://www.usenix.org/publications/login/standards/10.data.html |
37 | * (Andrew Josey <a.josey@opengroup.org>) : |
38 | * |
39 | * Data Type LP32 ILP32 ILP64 LLP64 LP64 |
40 | * char 8 8 8 8 8 |
41 | * short 16 16 16 16 16 |
42 | * int32 32 |
43 | * int 16 32 64 32 32 |
44 | * long 32 32 64 32 64 |
45 | * long long (int64) 64 |
46 | * pointer 32 32 64 64 64 |
47 | * |
48 | * With these constraints : |
49 | * sizeof(char) <= sizeof(short) <= sizeof(int) |
50 | * <= sizeof(long) = sizeof(size_t) |
51 | * |
52 | * and therefore sizeof(long) <= sizeof(pointer) <= sizeof(size_t) |
53 | * |
54 | * Which means we only have to remember which is the biggest type in a structure |
55 | * to know the structure's alignment. |
