tree-optimization/117559 - avoid hybrid SLP for masked load/store lanes
Hybrid analysis is confused by the mask_conversion pattern making a
uniform mask non-uniform. As load/store lanes only uses a single
lane to mask all data lanes the SLP graph doesn't cover the alternate
(redundant) mask lanes and thus their pattern defs. The following adds
a hack to mark them covered.
Fixes gcc.target/aarch64/sve/mask_struct_store_?.c with forced SLP.
PR tree-optimization/117559
* tree-vect-slp.cc (vect_mark_slp_stmts): Pass in vinfo,
mark all mask defs of a load/store-lane .MASK_LOAD/STORE
as pure.
(vect_make_slp_decision): Adjust.
(vect_slp_analyze_bb_1): Likewise.
