1132/* XCOFF archive support. The original version of this code was by
1133 Damon A. Permezel. It was enhanced to permit cross support, and
1134 writing archive files, by Ian Lance Taylor, Cygnus Support.
1135
1136 XCOFF uses its own archive format. Everything is hooked together
1137 with file offset links, so it is possible to rapidly update an
1138 archive in place. Of course, we don't do that. An XCOFF archive
1139 has a real file header, not just an ARMAG string. The structure of
1140 the file header and of each archive header appear below.
1141
1142 An XCOFF archive also has a member table, which is a list of
1143 elements in the archive (you can get that by looking through the
1144 linked list, but you have to read a lot more of the file). The
1145 member table has a normal archive header with an empty name. It is
1146 normally (and perhaps must be) the second to last entry in the
1147 archive. The member table data is almost printable ASCII. It
1148 starts with a 12 character decimal string which is the number of
1149 entries in the table. For each entry it has a 12 character decimal
1150 string which is the offset in the archive of that member. These
1151 entries are followed by a series of null terminated strings which
1152 are the member names for each entry.
1153
1154 Finally, an XCOFF archive has a global symbol table, which is what
1155 we call the armap. The global symbol table has a normal archive
1156 header with an empty name. It is normally (and perhaps must be)
1157 the last entry in the archive. The contents start with a four byte
1158 binary number which is the number of entries. This is followed by
1159 a that many four byte binary numbers; each is the file offset of an
1160 entry in the archive. These numbers are followed by a series of
5ea1af0d
GK		 1161 null terminated strings, which are symbol names.
1162
1163 AIX 4.3 introduced a new archive format which can handle larger
1164 files and also 32- and 64-bit objects in the same archive. The
1165 things said above remain true except that there is now more than
1166 one global symbol table. The one is used to index 32-bit objects,
1167 the other for 64-bit objects.
1168
1169 The new archives (recognizable by the new ARMAG string) has larger
1170 field lengths so that we cannot really share any code. Also we have
1171 to take care that we are not generating the new form of archives
1172 on AIX 4.2 or earlier systems. */

3211 R_TOC:
3212 TOC relative relocation. The value in the instruction in
3213 the input file is the offset from the input file TOC to
3214 the desired location. We want the offset from the final
3215 TOC to the desired location. We have:
3216 isym = iTOC + in
3217 iinsn = in + o
3218 osym = oTOC + on
3219 oinsn = on + o
3220 so we must change insn by on - in.

cf9ab45b 3224 is the address of the entry in the TOC section.
