Hi all,
I thought I'd throw this out here since as far as I can tell it isn't
used anymore, but other comments are welcome. I'm thinking of removing
the half-pic support from the mips backend. I can't think of a current
use for it and don't believe it's been used in years. Are there any
suggestions for a timeline, or can anyone think of a reason to keep it
around?
Thanks.

I think the discussion should be about half-pic across the entire
compiler. Does anyone know if any such OSF/1 systems are still live?
(And before anyone gets confused that's OSF/1 as distributed by OSF,
not OSF/1 nee DU nee Tru64 as distributed by Digital.)

The only time it was used was in OSF/1.0 (from OSF, not from DEC), which used
the OSF/rose object format (roughly 1990 time frame). OSF/1.1 used the
standard ELF tools (and no longer supported the MIPS anyway). I asked on the
OSF alums mailing list, and could find no extant users of the MIPS half-pic
stuff (which was sort half-baked anyway, and required you to pass -l options at
compile time for the libraries you intended to use). I think there may have 1
or 2 people with 386/486's with the x86 half-pic stuff, but they weren't
getting new compilers. I would drop support for the osfrose object file format
at the same time (from mips, x86, and ns32k). I've been meaning to do it for
years.

I just out a call to see if there were any people still using it. I suspect
not.
