    • gcse.c (cprop_cc0_jump): Function deleted. · 0e3f0221 
      
	* gcse.c (cprop_cc0_jump): Function deleted.
	(cprop_jump): Take an additional argument which is the possibly
	NULL cc setting insn immediately before the conditional jump.
	When a MODE_CC set is present, substitute it into the JUMP_INSN
	before attempting the constant propagation.
	(cprop_insn):  Recognize cc setters followed by conditional jumps
	as a special case.   Use cprop_jump instead of cprop_cc0_jump.
	(cprop_one_pass):  Call bypass_conditional_jumps if altering jumps.
	(find_bypass_set): New function based upon find_avail_set used by
	cprop, but finds constant expressions available at the end of
	basic blocks.
	(bypass_block): New function.  Given a basic block that begins
	with a conditional jump and multiple incoming edges, perform
	the jump bypass optimization.
	(bypass_conditional_jumps): New function.  Call bypass_block with
	each suitable basic block in the CFG using a simple single pass.
