tree-optimization/116974 - Handle single-lane SLP for OMP scan store
The following massages the GIMPLE matching way of handling scan
stores to work with single-lane SLP. I do not fully understand all
the cases that can happen and the stmt matching at vectorizable_store
time is less than ideal - but the following gets me all the testcases
to pass with and without forced SLP.
Long term we want to perform the matching at SLP discovery time,
properly chaining the various SLP instances the current state ends
up with.
PR tree-optimization/116974
* tree-vect-stmts.cc (check_scan_store): Pass in the SLP node
instead of just a flag. Allow single-lane scan stores.
(vectorizable_store): Adjust.
* tree-vect-loop.cc (vect_analyze_loop_2): Empty scan_map
before re-trying.
