Thanks.  I've checked in a fix for this (just make the args
unsigned ints).  It'll be in the next snapshot.

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

Yup.  Ran into it myself today while trying to get a 68k 4.4bsd
machine bootstrapped.

I'm going to look into having autoconf do it for us, but not
being an autoconf wiz, it might take a little while :-)

I've installed this patch, but without the #ifdef ADDRESS_COST

Re: One bug in unroll.c

	 I think if the current aliase code is released in
	egcs as is, the egcs project may start on a wrong foot. To the
	least, the first public release of egcs should not be worse
	than gcc2 ss-970802, which is egcs based upon.

The whole point of this project is to add new features and optimizations to
gcc.  There will of course be problems when new features are added in.

The intial list of new features (including the aliasing code) has certainly
caused problems, and we are working on fixing them as fast as we can.  It has
only been 7 days since the project started, though.  Give us some more time
to fix the bugs, and egcs will be as good as the gcc2 development sources
that we started with.

We will of course make a public release only when egcs is stable enough
for general use.

We will then add in some more features/optimizations and start all over
again with the bug fixing.

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.

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.

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.

New bugs in egcs

[H.J. Lu]

Hi,

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