/* 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. */

|

|
||
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.
|
||
|
||
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.
