[Bug libfortran/40344] New: O32 libgfortran.so fails to link on IRIX 6.5

[ro at gcc dot gnu dot org]

Between 20090402 (rev 145459) and 20090522 (rev 147798), the o32 libgfortran.so
failed to link, breaking IRIX 6 bootstrap:

I don't have an idea what is causing this yet.  When the same problem occured
up in the past, I tried to get more information on the ld error from SGI's Dave
Anderson, but unfortunately, he couldn't extract that from the linker
maintainers.  With Dave no longer at SGI and IRIX pratically EOL, the only
route may be do deprecate IRIX 6 O32 support wholesale.

Sounds like a linker bug. What was actually the solution for

Would it help to work around this issue by collecting the objects in one or
more
convenience archives and linking those (plus at least one plain object)
together
to form libgfortran.la?  The intermediate partially linked objects could hit a
different code path in the linker (but could also cause for some less-optimal
linking, at least with LTO?).  Of course 'ld -r' has been known to expose other
linker bugs so this might be trading one issue for an unknown other set...

A quick test indicates that this doesn't help.  I'm inclined to just drop
O32 ABI support given SGIs inability to fix (or even explain) the issue.
The N32/N64 linker is completely different and not hampered by such
problems.

I cannot see any point in retaining this PR against the gfortran target.

I am marking it, especially in light of Rainer's remarks, as WONTFIX.

Cheers

Ok with me.  I had meant for a long time to identify which changeset
broke linking the O32 libgfortran.so.  In the meantime, I've been
testing IRIX 6.5 with the O32 multilibs disabled globally.  But when I
recently retried bootstrap with all three multilibs and gas 2.20,
everything worked without problems.

So obviously this is all very fragile, and I may decide to deprecate the
IRIX 5 and O32 IRIX 6 ports in the future, should this problem come up
again.

        Rainer
