Roger Sayle bc6688b40e gcse.c (cprop_jump): Make use of REG_EQUAL notes on both setcc and jump, if they exist. 
* gcse.c (cprop_jump):  Make use of REG_EQUAL notes on both
	setcc and jump, if they exist.  If substituted instruction
	fails to validate, store current effort in a REG_EQUAL note.
	(cprop_insn): Don't attempt further substitutions if the
	current instruction has been deleted.
	(local_cprop_pass): Likewise.

	* jump.c (redirect_jump):  Also update REG_EQUAL note, if
	one is attached to the jump instruction.
	(invert_jump): Delete REG_EQUAL note on jump, if one exists.

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.
