1126 | /* XCOFF archive support. The original version of this code was by | |
1127 | Damon A. Permezel. It was enhanced to permit cross support, and | |
1128 | writing archive files, by Ian Lance Taylor, Cygnus Support. | |
1129 | ||
1130 | XCOFF uses its own archive format. Everything is hooked together | |
1131 | with file offset links, so it is possible to rapidly update an | |
1132 | archive in place. Of course, we don't do that. An XCOFF archive | |
1133 | has a real file header, not just an ARMAG string. The structure of | |
1134 | the file header and of each archive header appear below. | |
1135 | ||
1136 | An XCOFF archive also has a member table, which is a list of | |
1137 | elements in the archive (you can get that by looking through the | |
1138 | linked list, but you have to read a lot more of the file). The | |
1139 | member table has a normal archive header with an empty name. It is | |
1140 | normally (and perhaps must be) the second to last entry in the | |
1141 | archive. The member table data is almost printable ASCII. It | |
1142 | starts with a 12 character decimal string which is the number of | |
1143 | entries in the table. For each entry it has a 12 character decimal | |
1144 | string which is the offset in the archive of that member. These | |
1145 | entries are followed by a series of null terminated strings which | |
1146 | are the member names for each entry. | |
1147 | ||
1148 | Finally, an XCOFF archive has a global symbol table, which is what | |
1149 | we call the armap. The global symbol table has a normal archive | |
1150 | header with an empty name. It is normally (and perhaps must be) | |
1151 | the last entry in the archive. The contents start with a four byte | |
1152 | binary number which is the number of entries. This is followed by | |
1153 | a that many four byte binary numbers; each is the file offset of an | |
1154 | entry in the archive. These numbers are followed by a series of | |
5ea1af0d GK |
1155 | null terminated strings, which are symbol names. |
1156 | ||
1157 | AIX 4.3 introduced a new archive format which can handle larger | |
1158 | files and also 32- and 64-bit objects in the same archive. The | |
1159 | things said above remain true except that there is now more than | |
1160 | one global symbol table. The one is used to index 32-bit objects, | |
1161 | the other for 64-bit objects. | |
1162 | ||
1163 | The new archives (recognizable by the new ARMAG string) has larger | |
1164 | field lengths so that we cannot really share any code. Also we have | |
1165 | to take care that we are not generating the new form of archives | |
1166 | on AIX 4.2 or earlier systems. */ | |
