Jeff Law 74d2efc74c tree-ssa-dom.c (block_defs_stack): Remove, no longer needed. 
* tree-ssa-dom.c (block_defs_stack): Remove, no longer needed.
	(restore_currdefs_to_original_value): Likewise.
	(register_definitions_for_stmt): Likewise.
	(tree_ssa_dominator_optimize): No longer initialize CURRENT_DEF
	for each variable.  Do not allocate/free block_defs_stack either.
	Do not iterate if we just thread jumps.  Only iterate if the
	tree_cleanup_cfg does useful work (temporary).
	(dom_opt_initialize_block): No longer push a marker on
	BLOCK_DEFS_STACK.
	(dom_opt_finalize_block): Removal call to restore currdefs.
	Relax restrictions for recording edge equivalences.
	(record_equivalences_from_phis): No longer need to track
	CURRENT_DEF.
	(optimize_stmt): Similarly.
	(thread_across_edge): Simplify by removing the requirement that
	statements in the block we are threading through must be nops.
	(initialize_hash_element): Handle GOTO_EXPR.

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.
