tree-optimization/103102 - fix error in vectorizer refactoring
This fixes an oversight that caused vectorized epilogues to have
versioning for niters applied.
2021-11-08 Richard Biener <rguent...@suse.de>
* tree-vectorizer.h (vect_create_loop_vinfo): Add main_loop_info
parameter.
* tree-vect-loop.c (vect_create_loop_vinfo): Likewise. Set
LOOP_VINFO_ORIG_LOOP_INFO and conditionalize set of
LOOP_VINFO_NITERS_ASSUMPTIONS.
(vect_analyze_loop_1): Adjust.
(vect_analyze_loop): Move loop constraint setting and
SCEV/niter reset here from vect_create_loop_vinfo to perform
it only once.
(vect_analyze_loop_form): Move dumping of symbolic niters
here from vect_create_loop_vinfo.
