What happened to my SMP patch? The build cannot be done without it

It's in the queue.

However, you sent a patch without describing in any way, shape or
form what problem you were trying to solve.

As a result, it takes much longer to evaluate whether the patch
is necessary and correct -- which certainly puts it behind more
pressing issues in my queue like code generation and making single
threaded make work.

Maybe if you resent the patch and described the problem you were
trying to solve and your solution it would be more likely to go
into the tree in a timely fashion.

This would be my fault.  Sorry. I reported it just before 
effectively leaving town for a month.

I just applied it to today's egcs and it now no longer chokes 
when building new2.cc.   I haven't yet run the regressions on it,
but at least it builds.

Thanx for your help, Jim.

Suggestion re: 970825 Snapshot Available

I built egcs-ss-970821 for i486-linux-elf for c only, and it seems to
work, as far as my superficial tests can determine.  It's good to see
further development of gcc2.

I wondered if I could interest you in the following.  I imagine a lot
of people will be interested in trying egcs.  People with slow (modem
only) connections, like me, have some difficulty downloading egcs.  I
only have a 14.4k modem, and it took nearly two hours.  I guess many
people will have 28.8k or better modems, but it still takes on the
order of an hour.

Would you consider compressing egcs with a better compressor?  The
question would be a bit academic but for the fact that I can offer you
such a beast.  It's GNU GPL'd, patent-free, reasonably fast, portable,
and command-line compatible with gzip.

It saves nearly two megabytes for egcs:

   -rw-r--r--   37304320 Aug 25 12:04 egcs-ss-970821.tar
   -rw-r--r--    8043075 Aug 25 15:57 egcs-ss-970821.tar.gz
   -rw-r--r--    6169539 Aug 25 12:04 egcs-ss-970821.tar.bz2

For me that's around half an hour less on the phone, and also less
bandwidth on your servers.  Of course, people would have to download a
copy of the compressor, but that's about 300k for the source distrib,
or ~100k for a binary, so it would be a win even on the first
download.

The compressor's called "bzip2"; an early version of it has seen
some use in the Linux community over the past year.  You can
get it from http://www.muraroa.demon.co.uk .

Probably a rather strange-sounding proposition, but a serious one.

this week's patch for libgcc2-elf.a

[Robert Lipe]

This patch was originally against gcc2-970803, but it seems to 
vastly help egcs-970825.   Without it, libgcc2-elf.a doesn't 
contain any of the g++ stuff such as rtti.

I think there may still be a dependency missing, though.
