re PR tree-optimization/46590 (long compile time with -O2 and many loops)
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.
