snapshot 971122 and mips-sgi-irix6.2

[LeBlanc]

I had little difficulty compiling gas from the gas-970915 version
for the mips-sgi-irix6.2 configuration, but when I try to compile
the egcs snapshot 971122 with --with-gnu-as, I get an error as soon
as the new xgcc is used to compile enquire.c, because it tries to
pass the argument -n32 to gas.  I tried removing this from the
specs file, but this simply causes a lot of other errors.

Even if you do not specify --with-gnu-as, the xgcc will try to use
gas if there is a link to it is $(prefix)/mips-sgi-irix6.2/bin/as.

A further difficulty: if you type 'make bootstrap' in the egcs-971122
directory, it uses an old version of gcc to compile the first stage
of the bootstrap, but in the gcc directory the same command uses cc.

gas doesn't really support Irix 6.

It also shouldn't be necessary.  gcc should work on Irix 6 without
using gas.

I think gas is required on Irix 5 in order to get debugging
information, but not on Irix 6.

AFAICT you need at least GNU make to bootstrap.  I had no success
bootstrapping recent snapshots with (non-GNU) native tools (on irix6
and others).  Apparently other people have; I've no idea what we're
doing differently (aka wrongly) but would be interested in suggestions.

Does the irix6 assembler handle the difference of labels as used by
the EH unwind code?

I'm pretty sure the irix5 assembler does not handle this case correctly

Yes.  I had to work around a bug, but it works.

My understanding is for irix6 you should _not_ be using gas; you
should use the native assembler.
