Author: sayle
Date: Mon Feb 13 01:55:37 2006
New Revision: 110906

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=110906
Log:

	PR middle-end/25724
	* dojump.c (do_jump): Call do_compare_rtx_and_jump.
	(do_jump_parts_zero_rtx): New function renamed from
	do_jump_parts_equality_rtx.  Made static.  Add a mode argument.
	(do_jump_parts_equality_rtx): New function split out from
	do_jump_parts_equality.  Old implementation renamed as above.
	Call do_jump_parts_zero_rtx if either operand is zero.
	(do_jump_parts_equality): Call do_jump_parts_equality_rtx to
	do all of the heavy lifting.
	(do_compare_rtx_and_jump): Handle multi-word comparisons by
	calling either do_jump_by_parts_greater_rtx or
	do_jump_by_parts_equality_rtx.
	* expr.h (do_jump_by_parts_equality_rtx): Remove prototype.
	* expmed.c (do_cmp_and_jump): Now multi-word optimization has
	moved to do_compare_rtx_and_jump, call it directly.
	* stmt.c (do_jump_if_equal): Remove static prototype.  Add a
	mode argument.  Call do_compare_rtx_and_jump.
	(emit_case_nodes): Update calls to do_jump_if_equal.
