/* 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.  */

/* This is the relocation function for the RS/6000/POWER/PowerPC.
   This is currently the only processor which uses XCOFF; I hope that
   will never change.

   I took the relocation type definitions from two documents:
   the PowerPC AIX Version 4 Application Binary Interface, First
   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.  FIXME: We don't implement this,
   although we should for symbols of storage mapping class
   XMC_XO.

   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.
