20 | /* This file format can be used to compactly represent the information needed | |
21 | by a debugger to interpret the ANSI-C types used by a given program. | |
22 | Traditionally, this kind of information is generated by the compiler when | |
23 | invoked with the -g flag and is stored in "stabs" strings or in the more | |
24 | modern DWARF format. A new -gtLEVEL option has been added in gcc to generate | |
25 | such information. CTF provides a representation of only the information | |
26 | that is relevant to debugging a complex, optimized C program such as the | |
27 | operating system kernel in a form that is significantly more compact than | |
28 | the equivalent stabs or DWARF representation. The format is data-model | |
29 | independent, so consumers do not need different code depending on whether | |
30 | they are 32-bit or 64-bit programs. CTF assumes that a standard ELF symbol | |
31 | table is available for use in the debugger, and uses the structure and data | |
32 | of the symbol table to avoid storing redundant information. The CTF data | |
33 | may be compressed on disk or in memory, indicated by a bit in the header. | |
34 | CTF may be interpreted in a raw disk file, or it may be stored in an ELF | |
35 | section, typically named .ctf. Data structures are aligned so that a raw | |
36 | CTF file or CTF ELF section may be manipulated using mmap(2). | |
37 | ||
38 | The CTF file or section itself has the following structure: | |
39 | ||
40 | +--------+--------+---------+----------+----------+-------+--------+ | |
41 | | file | type | data | function | variable | data | string | | |
42 | | header | labels | objects | info | info | types | table | | |
43 | +--------+--------+---------+----------+----------+-------+--------+ | |
44 | ||
45 | The file header stores a magic number and version information, encoding | |
46 | flags, and the byte offset of each of the sections relative to the end of the | |
47 | header itself. If the CTF data has been uniquified against another set of | |
09f2921c | 48 | CTF data, a reference to that data also appears in the header. This |
30d1f018 WP |
49 | reference is the name of the label corresponding to the types uniquified |
50 | against. | |
51 | ||
52 | Following the header is a list of labels, used to group the types included in | |
53 | the data types section. Each label is accompanied by a type ID i. A given | |
54 | label refers to the group of types whose IDs are in the range [0, i]. | |
55 | ||
56 | Data object and function records are stored in the same order as they appear | |
57 | in the corresponding symbol table, except that symbols marked SHN_UNDEF are | |
58 | not stored and symbols that have no type data are padded out with zeroes. | |
59 | For each data object, the type ID (a small integer) is recorded. For each | |
60 | function, the type ID of the return type and argument types is recorded. | |
61 | ||
62 | Variable records (as distinct from data objects) provide a modicum of support | |
63 | for non-ELF systems, mapping a variable name to a CTF type ID. The variable | |
64 | names are sorted into ASCIIbetical order, permitting binary searching. | |
65 | ||
66 | The data types section is a list of variable size records that represent each | |
67 | type, in order by their ID. The types themselves form a directed graph, | |
68 | where each node may contain one or more outgoing edges to other type nodes, | |
69 | denoted by their ID. | |
70 | ||
71 | Strings are recorded as a string table ID (0 or 1) and a byte offset into the | |
72 | string table. String table 0 is the internal CTF string table. String table | |
73 | 1 is the external string table, which is the string table associated with the | |
74 | ELF symbol table for this object. CTF does not record any strings that are | |
75 | already in the symbol table, and the CTF string table does not contain any | |
76 | duplicated strings. */ | |
