Hi,
I am seeing an internal compiler error, related to this patch: during GIMPLE pass: slp options-save.cc: In function 'void cl_optimization_restore(gcc_options*, gcc_options*, cl_optimization*)': options-save.cc:1292:1: internal compiler error: in supportable_widening_operation, at tree-vect-stmts.cc:12199 1292 | cl_optimization_restore (struct gcc_options *opts, struct gcc_options *opts_set, | ^~~~~~~~~~~~~~~~~~~~~~~ /…/src/gcc/gcc/profile-count.cc: In member function 'int profile_count::to_cgraph_frequency(profile_count) const': /…/src/gcc/gcc/profile-count.cc:308:1: note: parameter passing for argument of type 'profile_count' changed in GCC 9.1 308 | profile_count::to_cgraph_frequency (profile_count entry_bb_count) const | ^~~~~~~~~~~~~ /…/src/gcc/gcc/profile-count.cc: In member function 'sreal profile_count::to_sreal_scale(profile_count, bool*) const': /…/src/gcc/gcc/profile-count.cc:326:1: note: parameter passing for argument of type 'profile_count' changed in GCC 9.1 326 | profile_count::to_sreal_scale (profile_count in, bool *known) const | ^~~~~~~~~~~~~ 0x2195bdd supportable_widening_operation(vec_info*, tree_code, _stmt_vec_info*, tree_node*, tree_node*, tree_code*, tree_code*, int*, vec<tree_node*, va_heap, vl_ptr>*) /…/src/gcc/gcc/tree-vect-stmts.cc:12199 0x2180493 vectorizable_conversion /…/src/gcc/gcc/tree-vect-stmts.cc:5064 0x2192fdd vect_analyze_stmt(vec_info*, _stmt_vec_info*, bool*, _slp_tree*, _slp_instance*, vec<stmt_info_for_cost, va_heap, vl_ptr>*) /…/src/gcc/gcc/tree-vect-stmts.cc:11256 /…/src/gcc/gcc/profile-count.cc: In member function 'profile_count profile_count::combine_with_ipa_count(profile_count)': /…/src/gcc/gcc/profile-count.cc:398:1: note: parameter passing for argument of type 'profile_count' changed in GCC 9.1 398 | profile_count::combine_with_ipa_count (profile_count ipa) | ^~~~~~~~~~~~~ 0x14f95d1 vect_slp_analyze_node_operations_1 /…/src/gcc/gcc/tree-vect-slp.cc:5958 0x14f9c19 vect_slp_analyze_node_operations /…/src/gcc/gcc/tree-vect-slp.cc:6147 0x14f9b4d vect_slp_analyze_node_operations /…/src/gcc/gcc/tree-vect-slp.cc:6126 0x14fa439 vect_slp_analyze_operations(vec_info*) /…/src/gcc/gcc/tree-vect-slp.cc:6387 0x14fd423 vect_slp_analyze_bb_1 /…/src/gcc/gcc/tree-vect-slp.cc:7372 0x14fd599 vect_slp_region /…/src/gcc/gcc/tree-vect-slp.cc:7419 0x14fe0d1 vect_slp_bbs /…/src/gcc/gcc/tree-vect-slp.cc:7610 0x14fe46f vect_slp_function(function*) /…/src/gcc/gcc/tree-vect-slp.cc:7698 0x151a109 execute /…/src/gcc/gcc/tree-vectorizer.cc:1532 Please submit a full bug report, with preprocessed source (by using -freport-bug).

Instead we look for the inner mode type and use build_vector_type_for_mode instead. Bootstrapped and tested on x86_64-unknown-linux-gnu, pushed.
