Adjust BB vectorization function splitting
This adjusts the condition when to split at control altering stmts,
only when there's a definition. It also removes the only use
of --param slp-max-insns-in-bb which a previous change left doing
nothing (but repeatedly print a message for each successive
instruction...).
2020-10-27 Richard Biener <rguenther@suse.de>
* tree-vect-slp.c (vect_slp_bbs): Remove no-op
slp-max-insns-in-bb check.
(vect_slp_function): Dump when splitting the function.
Adjust the split condition for control altering stmts.
* params.opt (-param=slp-max-insns-in-bb): Remove.
* doc/invoke.texi (-param=slp-max-insns-in-bb): Likewise.
