2014-01-17  Richard Biener  <rguenther@suse.de>

	PR tree-optimization/46590
	* opts.c (default_options_table): Add entries for
	OPT_fbranch_count_reg, OPT_fmove_loop_invariants and OPT_ftree_pta,
	all enabled at -O1 but not for -Og.
	* common.opt (fbranch-count-reg): Remove Init(1).
	(fmove-loop-invariants): Likewise.
	(ftree-pta): Likewise.
