New Revision: 141198

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=141198
Log:
	* gcc-interface/trans.c (gnat_to_gnu) <N_Slice>: Simplify expansion
	to use only a single check instead of three, and avoid unnecessary
	COMPOUND_EXPR.
	(emit_check): Avoid useless COMPOUND_EXPRs and SAVE_EXPRs, sometimes
	creating more opportunities for optimizations.
