re PR middle-end/92046 (Command line options (that are per-functions) are affecting --params which are global.)
2019-10-10 Richard Biener <rguenther@suse.de>
PR middle-end/92046
* opts.c (finish_options): Do not influence global --params
from options that are adjustable per function.
* tree-vect-data-refs.c (vect_enhance_data_refs_alignment):
Apply --param adjustment based on active cost-model.
* tree-ssa-phiopt.c (cond_if_else_store_replacement): Disable
further store-sinking when vectorization or if-conversion
are not enabled.
