I don't know.   I'm not planning to maintain anything - I'm just
kicking in some help.

It's gone.

Good catch.  Since 971014 has been there for some time and isn't on
the list of things known to fail, something must have fixed it.

IMO, you can vote which one stays and which one goes.  You can even
make the changes yourself if you like.

This is why I'm leaning toward the liberal inclusion of testcase
information in the cases themselves.  I haven't been that liberal with
everything, trying to strike a balance between volume and completeness.

Done.

It failed on egcs 1.0.1 when I tried it last night.   Aaah.  I see the
fix in 1.0.2.

Does anyone know how we can make those tests run with '-fPIC -O' so they'll
show up as a failure?

Dave, you get the vote which of those tests we keep.

I think it was this fix:

Mon Jan 19 21:57:00 1998  Richard Henderson  <rth@cygnus.com>

        * i386.md (push): Prohibit symbolic constants if flag_pic.
        (movsi+1): Likewise for move to non-register.

If you decide that either or both of these tests stay, one of us can
blow this reference into the testcases if you like.

That's the same file twice.   Presumably you mean *-6.f  and *-8.f.

I'll let you pick which stays.

I hate to admit this in this crowd, but I don't do emacs.   Are you
saying that the value of the space is greater than the value
of the comments?   If so, I can swing back the other way and not
retain sender information, etc.


Thanx for the help.
