1029 /* XCOFF archive support. The original version of this code was by
1030 Damon A. Permezel. It was enhanced to permit cross support, and
1031 writing archive files, by Ian Lance Taylor, Cygnus Support.
1033 XCOFF uses its own archive format. Everything is hooked together
1034 with file offset links, so it is possible to rapidly update an
1035 archive in place. Of course, we don't do that. An XCOFF archive
1036 has a real file header, not just an ARMAG string. The structure of
1037 the file header and of each archive header appear below.
1039 An XCOFF archive also has a member table, which is a list of
1040 elements in the archive (you can get that by looking through the
1041 linked list, but you have to read a lot more of the file). The
1042 member table has a normal archive header with an empty name. It is
1043 normally (and perhaps must be) the second to last entry in the
1044 archive. The member table data is almost printable ASCII. It
1045 starts with a 12 character decimal string which is the number of
1046 entries in the table. For each entry it has a 12 character decimal
1047 string which is the offset in the archive of that member. These
1048 entries are followed by a series of null terminated strings which
1049 are the member names for each entry.
1051 Finally, an XCOFF archive has a global symbol table, which is what
1052 we call the armap. The global symbol table has a normal archive
1053 header with an empty name. It is normally (and perhaps must be)
1054 the last entry in the archive. The contents start with a four byte
1055 binary number which is the number of entries. This is followed by
1056 a that many four byte binary numbers; each is the file offset of an
1057 entry in the archive. These numbers are followed by a series of
1058 null terminated strings, which are symbol names.
1060 AIX 4.3 introduced a new archive format which can handle larger
1061 files and also 32- and 64-bit objects in the same archive. The
1062 things said above remain true except that there is now more than
1063 one global symbol table. The one is used to index 32-bit objects,
1064 the other for 64-bit objects.
1066 The new archives (recognizable by the new ARMAG string) has larger
1067 field lengths so that we cannot really share any code. Also we have
1068 to take care that we are not generating the new form of archives
1069 on AIX 4.2 or earlier systems. */

3209 relative branches which use half of the difference
3210 between the symbol and the program counter. I can't
3211 quite figure out when this is useful. These relocs are
3212 not defined by the PowerOpen ABI.
3217 Simple positive relocation.
3220 Simple negative relocation.
3223 Simple PC relative relocation.
3226 TOC relative relocation. The value in the instruction in
3227 the input file is the offset from the input file TOC to
3228 the desired location. We want the offset from the final
3229 TOC to the desired location. We have:
3234 so we must change insn by on - in.
3237 GL linkage relocation. The value of this relocation
3238 is the address of the entry in the TOC section.
3241 Local object TOC address. I can't figure out the
3242 difference between this and case R_GL.
3245 TOC relative relocation. A TOC relative load instruction
3246 which may be changed to a load address instruction.
3247 FIXME: We don't currently implement this optimization.
3250 TOC relative relocation. This is a TOC relative load
3251 address instruction which may be changed to a load
3252 instruction. FIXME: I don't know if this is the correct
3256 Absolute branch. We don't want to mess with the lower
3257 two bits of the instruction.
3260 The PowerPC ABI defines this as an absolute call which
3261 may be modified to become a relative call. The PowerOpen
3262 ABI does not define this relocation type.
3265 Absolute branch which may be modified to become a
