FYI: patches for powerpc-aix...

[Joel Brobecker]

Hello,

Re: DWARF support with GNU as/ld on AIX:
        http://sourceware.org/ml/binutils/2011-04/msg00250.html
        http://www.sourceware.org/ml/gdb/2013-01/msg00030.html

I have been spending some time trying to gather and test our patches.
Unfortunately, I am running out of time for this week, and will
probably not be able to complete this task until later. Everything
tested fine when applying the patches to the sources as of Oct 18,
but I get an abort in gas with today's HEAD:

    /tmp//ccY5Nx8U.s: Assembler messages:
    /tmp//ccY5Nx8U.s:241: Internal error, aborting at /homes/brobecke/act/binutils/binutils-head/gas/config/tc-ppc.c line 3319 in md_assemble
    Please report this bug.
    gnatmake: *** link failed.

I had a quick look at the code in question, and my guess is that
it is not something that would be very hard to fix.

In the meantime, attached are the patches I have identified, in case
someone is interested. I will send a proper submission after I've
fixed the abort and tested them properly. The description of each
patch will also be provided then. Comments and suggestions are
of course always welcome.
