tree-optimization/114736 - SLP DFS walk issue
The following fixes a DFS walk issue when identifying to be ignored
latch edges. We have (bogus) SLP_TREE_REPRESENTATIVEs for VEC_PERM
nodes so those have to be explicitly ignored as possibly being PHIs.
PR tree-optimization/114736
* tree-vect-slp.cc (vect_optimize_slp_pass::is_cfg_latch_edge):
Do not consider VEC_PERM_EXPRs as PHI use.
* gfortran.dg/vect/pr114736.f90: New testcase.
