	(find_sub_basic_blocks): Revamp to use make_edges
	and purge_dead_edges.
	(find_basic_blocks): Update call of find_sub_basic_block.

	* recog.c (split_all_insns): Always expect CFG to be consistent;
	call find_sub_basic_blocks in case something has changed.
	* toplev.c (rest_of_compilation): Always call split_all_insns once CFG
	has been built.

	* basic-block.h (delete_noop_moves): Declare.
	* combine.c (combine_instructions): Call it.
	(recog_for_combine): Tolerate noop moves
	(distribute_notes): Force refresh when register dies at noop move.
	* flow.c (delete_noop_moves): Use BB structure; delete JUMP insns
	too.

	* toplev.c (rest_of_compilation): Conditionally call purge_all_dead_edges
	after combine.
	* gcse.c (cprop_cc0_jump, cprop_insn): New argument "basic_block".
	(cprop_jump): Likewise; call purge_dead_edges if substitution suceeded.

README 

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the file COPYING
for copying permission.  The manuals, and some of the runtime
libraries, are under different terms; see the individual source files
for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
