25 | SECTION |
26 | Archives |
27 | |
28 | DESCRIPTION |
29 | An archive (or library) is just another BFD. It has a symbol |
30 | table, although there's not much a user program will do with it. |
31 | |
32 | The big difference between an archive BFD and an ordinary BFD |
33 | is that the archive doesn't have sections. Instead it has a |
34 | chain of BFDs that are considered its contents. These BFDs can |
35 | be manipulated like any other. The BFDs contained in an |
36 | archive opened for reading will all be opened for reading. You |
37 | may put either input or output BFDs into an archive opened for |
38 | output; they will be handled correctly when the archive is closed. |
39 | |
40 | Use <<bfd_openr_next_archived_file>> to step through |
41 | the contents of an archive opened for input. You don't |
42 | have to read the entire archive if you don't want |
43 | to! Read it until you find what you want. |
44 | |
45 | Archive contents of output BFDs are chained through the |
46 | <<next>> pointer in a BFD. The first one is findable through |
47 | the <<archive_head>> slot of the archive. Set it with |
48 | <<bfd_set_archive_head>> (q.v.). A given BFD may be in only one |
49 | open output archive at a time. |
50 | |
51 | As expected, the BFD archive code is more general than the |
52 | archive code of any given environment. BFD archives may |
53 | contain files of different formats (e.g., a.out and coff) and |
54 | even different architectures. You may even place archives |
55 | recursively into archives! |
56 | |
57 | This can cause unexpected confusion, since some archive |
58 | formats are more expressive than others. For instance, Intel |
59 | COFF archives can preserve long filenames; SunOS a.out archives |
60 | cannot. If you move a file from the first to the second |
61 | format and back again, the filename may be truncated. |
62 | Likewise, different a.out environments have different |
63 | conventions as to how they truncate filenames, whether they |
64 | preserve directory names in filenames, etc. When |
65 | interoperating with native tools, be sure your files are |
66 | homogeneous. |
67 | |
68 | Beware: most of these formats do not react well to the |
69 | presence of spaces in filenames. We do the best we can, but |
70 | can't always handle this case due to restrictions in the format of |
71 | archives. Many Unix utilities are braindead in regards to |
72 | spaces and such in filenames anyway, so this shouldn't be much |
73 | of a restriction. |
74 | |
75 | Archives are supported in BFD in <<archive.c>>. |
76 | |
77 | */ |
78 | |
79 | /* Assumes: |
80 | o - all archive elements start on an even boundary, newline padded; |
81 | o - all arch headers are char *; |
82 | o - all arch headers are the same size (across architectures). |
83 | */ |
84 | |
85 | /* Some formats provide a way to cram a long filename into the short |
86 | (16 chars) space provided by a BSD archive. The trick is: make a |
87 | special "file" in the front of the archive, sort of like the SYMDEF |
88 | entry. If the filename is too long to fit, put it in the extended |
89 | name table, and use its index as the filename. To prevent |
90 | confusion prepend the index with a space. This means you can't |
91 | have filenames that start with a space, but then again, many Unix |
92 | utilities can't handle that anyway. |
93 | |
94 | This scheme unfortunately requires that you stand on your head in |
95 | order to write an archive since you need to put a magic file at the |
96 | front, and need to touch every entry to do so. C'est la vie. |
97 | |
98 | We support two variants of this idea: |
99 | The SVR4 format (extended name table is named "//"), |
100 | and an extended pseudo-BSD variant (extended name table is named |
101 | "ARFILENAMES/"). The origin of the latter format is uncertain. |
102 | |
103 | BSD 4.4 uses a third scheme: It writes a long filename |
104 | directly after the header. This allows 'ar q' to work. |
105 | We currently can read BSD 4.4 archives, but not write them. |
106 | */ |
107 | |
108 | /* Summary of archive member names: |
109 | |
110 | Symbol table (must be first): |
111 | "__.SYMDEF " - Symbol table, Berkeley style, produced by ranlib. |
112 | "/ " - Symbol table, system 5 style. |
113 | |
114 | Long name table (must be before regular file members): |
115 | "// " - Long name table, System 5 R4 style. |
116 | "ARFILENAMES/ " - Long name table, non-standard extended BSD (not BSD 4.4). |
117 | |
118 | Regular file members with short names: |
119 | "filename.o/ " - Regular file, System 5 style (embedded spaces ok). |
120 | "filename.o " - Regular file, Berkeley style (no embedded spaces). |
121 | |
122 | Regular files with long names (or embedded spaces, for BSD variants): |
123 | "/18 " - SVR4 style, name at offset 18 in name table. |
124 | "#1/23 " - Long name (or embedded paces) 23 characters long, |
125 | BSD 4.4 style, full name follows header. |
126 | Implemented for reading, not writing. |
127 | " 18 " - Long name 18 characters long, extended pseudo-BSD. |
