1194 | /* XCOFF archive support. The original version of this code was by | |
1195 | Damon A. Permezel. It was enhanced to permit cross support, and | |
1196 | writing archive files, by Ian Lance Taylor, Cygnus Support. | |
1197 | ||
1198 | XCOFF uses its own archive format. Everything is hooked together | |
1199 | with file offset links, so it is possible to rapidly update an | |
1200 | archive in place. Of course, we don't do that. An XCOFF archive | |
1201 | has a real file header, not just an ARMAG string. The structure of | |
1202 | the file header and of each archive header appear below. | |
1203 | ||
1204 | An XCOFF archive also has a member table, which is a list of | |
1205 | elements in the archive (you can get that by looking through the | |
1206 | linked list, but you have to read a lot more of the file). The | |
1207 | member table has a normal archive header with an empty name. It is | |
1208 | normally (and perhaps must be) the second to last entry in the | |
1209 | archive. The member table data is almost printable ASCII. It | |
1210 | starts with a 12 character decimal string which is the number of | |
1211 | entries in the table. For each entry it has a 12 character decimal | |
1212 | string which is the offset in the archive of that member. These | |
1213 | entries are followed by a series of null terminated strings which | |
1214 | are the member names for each entry. | |
1215 | ||
1216 | Finally, an XCOFF archive has a global symbol table, which is what | |
1217 | we call the armap. The global symbol table has a normal archive | |
1218 | header with an empty name. It is normally (and perhaps must be) | |
1219 | the last entry in the archive. The contents start with a four byte | |
1220 | binary number which is the number of entries. This is followed by | |
1221 | a that many four byte binary numbers; each is the file offset of an | |
1222 | entry in the archive. These numbers are followed by a series of | |
5ea1af0d GK |
1223 | null terminated strings, which are symbol names. |
1224 | ||
1225 | AIX 4.3 introduced a new archive format which can handle larger | |
1226 | files and also 32- and 64-bit objects in the same archive. The | |
1227 | things said above remain true except that there is now more than | |
1228 | one global symbol table. The one is used to index 32-bit objects, | |
1229 | the other for 64-bit objects. | |
1230 | ||
1231 | The new archives (recognizable by the new ARMAG string) has larger | |
1232 | field lengths so that we cannot really share any code. Also we have | |
1233 | to take care that we are not generating the new form of archives | |
1234 | on AIX 4.2 or earlier systems. */ | |

3267 | isym = iTOC + in | |
3268 | iinsn = in + o | |
3269 | osym = oTOC + on | |
3270 | oinsn = on + o | |
