tree-optimization/116791 - Elementwise SLP vectorization
The following restricts the elementwise SLP vectorization to the
single-lane case which is the reason I enabled it to avoid regressions
with non-SLP. The PR shows that multi-line SLP loads with elementwise
accesses require work, I'll open a new bug to track this for the
future.
PR tree-optimization/116791
* tree-vect-stmts.cc (get_group_load_store_type): Only
fall back to elementwise access for single-lane SLP, restore
hard failure mode for other cases.
* gcc.dg/vect/pr116791.c: New testcase.
