+/* XCOFF archive support. The original version of this code was by
+ Damon A. Permezel. It was enhanced to permit cross support, and
+ writing archive files, by Ian Lance Taylor, Cygnus Support.
+
+ XCOFF uses its own archive format. Everything is hooked together
+ with file offset links, so it is possible to rapidly update an
+ archive in place. Of course, we don't do that. An XCOFF archive
+ has a real file header, not just an ARMAG string. The structure of
+ the file header and of each archive header appear below.
+
+ An XCOFF archive also has a member table, which is a list of
+ elements in the archive (you can get that by looking through the
+ linked list, but you have to read a lot more of the file). The
+ member table has a normal archive header with an empty name. It is
+ normally (and perhaps must be) the second to last entry in the
+ archive. The member table data is almost printable ASCII. It
+ starts with a 12 character decimal string which is the number of
+ entries in the table. For each entry it has a 12 character decimal
+ string which is the offset in the archive of that member. These
+ entries are followed by a series of null terminated strings which
+ are the member names for each entry.
+
+ Finally, an XCOFF archive has a global symbol table, which is what
+ we call the armap. The global symbol table has a normal archive
+ header with an empty name. It is normally (and perhaps must be)
+ the last entry in the archive. The contents start with a four byte
+ binary number which is the number of entries. This is followed by
+ a that many four byte binary numbers; each is the file offset of an
+ entry in the archive. These numbers are followed by a series of
+ null terminated strings, which are symbol names.
+
+ AIX 4.3 introduced a new archive format which can handle larger
+ files and also 32- and 64-bit objects in the same archive. The
+ things said above remain true except that there is now more than
+ one global symbol table. The one is used to index 32-bit objects,
+ the other for 64-bit objects.
+
+ The new archives (recognizable by the new ARMAG string) has larger
+ field lengths so that we cannot really share any code. Also we have
+ to take care that we are not generating the new form of archives
+ on AIX 4.2 or earlier systems. */
+
+/* PR 21786: The PE/COFF standard does not require NUL termination for any of
+ the ASCII fields in the archive headers. So in order to be able to extract
+ numerical values we provide our own versions of strtol and strtoll which
+ take a maximum length as an additional parameter. Also - just to save space,
+ we omit the endptr return parameter, since we know that it is never used. */

+ Edition (April 1992), and the PowerOpen ABI, Big-Endian
+ 32-Bit Hardware Implementation (June 30, 1994). Differences
+ between the documents are noted below.
+
+ Unsupported r_type's
+
+ R_RTB:
+ R_RRTBI:
+ R_RRTBA:
+
+ These relocs are defined by the PowerPC ABI to be
+ relative branches which use half of the difference
+ between the symbol and the program counter. I can't
+ quite figure out when this is useful. These relocs are
+ not defined by the PowerOpen ABI.
+
+ Supported r_type's
+
+ R_POS:
+ Simple positive relocation.
+
+ R_NEG:
+ Simple negative relocation.
+
+ R_REL:
+ Simple PC relative relocation.
+
+ R_TOC:
+ TOC relative relocation. The value in the instruction in
+ the input file is the offset from the input file TOC to
+ the desired location. We want the offset from the final
+ TOC to the desired location. We have:
+ isym = iTOC + in
+ iinsn = in + o
+ osym = oTOC + on
+ oinsn = on + o
+ so we must change insn by on - in.
+
+ R_GL:
+ GL linkage relocation. The value of this relocation
+ is the address of the entry in the TOC section.
+
+ R_TCL:
+ Local object TOC address. I can't figure out the
+ difference between this and case R_GL.
+
+ R_TRL:
+ TOC relative relocation. A TOC relative load instruction
+ which may be changed to a load address instruction.
+ FIXME: We don't currently implement this optimization.
+
+ R_TRLA:
+ TOC relative relocation. This is a TOC relative load
+ address instruction which may be changed to a load
+ instruction. FIXME: I don't know if this is the correct
+ implementation.
+
+ R_BA:
+ Absolute branch. We don't want to mess with the lower
+ two bits of the instruction.
+
+ R_CAI:
+ The PowerPC ABI defines this as an absolute call which
+ may be modified to become a relative call. The PowerOpen
+ ABI does not define this relocation type.
+
+ R_RBA:
+ Absolute branch which may be modified to become a
+ relative branch.
+
+ R_RBAC:
+ The PowerPC ABI defines this as an absolute branch to a
+ fixed address which may be modified to an absolute branch
+ to a symbol. The PowerOpen ABI does not define this
+ relocation type.
+
+ R_RBRC:
+ The PowerPC ABI defines this as an absolute branch to a
+ fixed address which may be modified to a relative branch.
+ The PowerOpen ABI does not define this relocation type.
+
+ R_BR:
+ Relative branch. We don't want to mess with the lower
+ two bits of the instruction.
+
+ R_CREL:
+ The PowerPC ABI defines this as a relative call which may
+ be modified to become an absolute call. The PowerOpen
+ ABI does not define this relocation type.
+
+ R_RBR:
+ A relative branch which may be modified to become an
+ absolute branch.
+
+ R_RL:
+ The PowerPC AIX ABI describes this as a load which may be
+ changed to a load address. The PowerOpen ABI says this
+ is the same as case R_POS.
+
+ R_RLA:
+ The PowerPC AIX ABI describes this as a load address
+ which may be changed to a load. The PowerOpen ABI says
+ this is the same as R_POS.
