tree-optimization/117484 - issue with SLP discovery of permuted .MASK_LOAD
When we do SLP discovery of a .MASK_LOAD for a dataref group with gaps
the discovery for the mask will have gaps as well and this was
unexpected in a few places. The following re-organizes things
slightly to accomodate for this.
PR tree-optimization/117484
* tree-vect-slp.cc (vect_build_slp_tree_2): Handle gaps in
mask discovery. Fix condition to release the load permutation.
(vect_lower_load_permutations): Assert we get no load
permutation for the unpermuted node.
* tree-vect-slp-patterns.cc (linear_loads_p): Properly identify
loads (without permutation).
(compatible_complex_nodes_p): Likewise.
* gcc.dg/vect/pr117484-1.c: New testcase.
* gcc.dg/vect/pr117484-2.c: Likewise.
