/* 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. */

The original version was based on two documents:
|
2012-03-26 19:18:29 +00:00
|
|
|
|
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.

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.
|
2022-10-27 18:45:45 +00:00
|
|
|
|
This relocation allows the linker to perform optimizations
|
|
|
|
|
by transforming a load instruction into a add-immediate
|
|
|
|
|
when possible. The relocation is, then, changed to R_TRLA
|
|
|
|
|
in the output file.
|
|
|
|
|
TODO: Currently, the optimisation isn't implemented.
|
|
|
|
|
|
|
|
|
|
R_TRL:
|
|
|
|
|
TOC relative relocation. Same as R_TOC, except that
|
|
|
|
|
the optimization isn't allowed
|
|
|
|
|
|
|
|
|
|
R_TRLA:
|
|
|
|
|
TOC relative relocation. This is a TOC relative load
|
|
|
|
|
address instruction which have been changed to an add-
|
|
|
|
|
immediate instruction.
|

|
|
|
|
|
|
|
|
|
R_GL:
|
|
|
|
|
GL linkage relocation. The value of this relocation
|
2022-10-27 18:45:45 +00:00
|
|
|
|
is the address of the external symbol in the TOC
|
|
|
|
|
section.

|
|

difference between this and case R_GL.

R_RL:

|
|

this is the same as R_POS.
|
|
|
|

|
|
|
|
R_REF:
|
|
|
|
|
Not a relocation but a way to prevent the garbage
|
|
|
|
|
collector of AIX linker to remove symbols.
|
|
|
|
|
This is not needed in our case.
