2011-06-29  Richard Guenther  <rguenther@suse.de>

	* doc/invoke.texi: Document -scev dump modifier.
	* tree-pass.h (TDF_SCEV): New dump flag.
	* tree-dump.c (dump_option_value_in): Add scev.
	* tree-chrec.c: Replace all TDF_DETAILS checks with TDF_SCEV.
	* tree-scalar-evolution.c: Likewise.

	* gcc.dg/tree-ssa/loop-17.c: Adjust.
