Memory consumption for bootstrap explodes

[David Edelsohn]

	It's probably one of:

Sun Jul 21 21:36:41 CEST 2002  Jan Hubicka  <jh@suse.cz>

	* gcse.c (do_local_cprop): Do not extend lifetimes of registers set by
	do_local_cprop.

2002-07-21  Bernd Schmidt  <bernds@redhat.com>

	Improvements for the ifcvt pass from Michael Meissner, with patches
	by Richard Sandiford <rsandifo@redhat.com>

Sun Jul 21 00:54:54 CEST 2002  Jan Hubicka  <jh@suse.cz>

	* gcse.c: Include cselib.h
	(constptop_register): Break out from ...
	(cprop_insn): ... here; kill basic_block argument.
	(do_local_cprop, local_cprop_pass): New functions.
	(one_cprop_pass): Call local_cprop_pass.


Can you just try reverting those patches one by one to see where memory
usage goes back down?
