re PR tree-optimization/90911 (456.hmmer regression with r272239)
2019-07-04 Richard Biener <rguenther@suse.de>
PR tree-optimization/90911
* tree-vectorizer.h (_loop_vec_info::scalar_loop_scaling): New field.
(LOOP_VINFO_SCALAR_LOOP_SCALING): new.
* tree-vect-loop.c (_loop_vec_info::_loop_vec_info): Initialize
scalar_loop_scaling.
(vect_transform_loop): Scale scalar loop profile if needed.
* tree-vect-loop-manip.c (vect_loop_versioning): When re-using
the loop copy from if-conversion adjust edge probabilities
and scale the vectorized loop body profile, queue the scalar
profile for updating after peeling.
