Close :-) the stage2 compiler chokes on data.c during the stage3
build.

I've got a 68k bootstrap running right now; it'll take a _long_
time to finish, but hopefully it'll enable me to track down some
of your problems (assuming they're generic 68k bugs).

Here is the partial list. Somehow egcs screws up the real constant
numbers when the compiler is compiled with -O6 -g. I am looking into
it. I may not be able to find time before next weekend.

Also, that cp/tree.c change bug I reported earlier still exists,
although it is also in gcc2 ss-970802.

I also reported/fixed a few bugs and I have sent my patches to
gcc2. Should I resend them to egcs? My patches may look ugly. But
the bugs are real.

Ummm, what I remember reading was that your _patch_ was incorrect;
I don't think Jason (or anyone) said that it was not a bug.  He
asked you to verify that the bug still exists after the next snapshot.

Please do that with tonight's snapshot using the libstdc++ included
therein (no, I haven't made the snapshot yet, but the plan is to
get it done before I go to sleep tongiht).

	Great. Now only if I can compile libg++ with egcs. Is someone
	working on that cp/tree.c bug I reported?

I am looking into all bugs that have been reported (excepting C++ ones out
of my area of expertise).  Please be patient, and I will get to it as soon
as I can.

Thanks.

But I was told that it was not a bug while I am keeping getting it. I
am afraid that egcs may be released with that cp/tree.c bug, which may
be specific to x86.

	Those extra failures don't exist in my gcc2 ss-970802.

These problems all go away with my alias.c patch and jfc's unroll.c patch
applied.

I get exactly the same c-torture results for egcs and gcc2, with egcs
bootstrapped using -O6 -g.

So, after re-building gcc with jfc's patch, then re-running the
testsuite, how many of these new failures remain?

Hi,

Those extra failures don't exist in my gcc2 ss-970802.
