7309 arguments and initialize bitregion_{start,end} from those.
7310 (struct merged_store_group): Add bitregion_start, bitregion_end,
7311 align_base and mask fields. Drop unnecessary struct keyword from
7312 struct store_immediate_info. Add do_merge method.

7314 (merged_store_group::do_merge): New method.

7317 (merged_store_group::merge_overlapping): Use do_merge.
7318 (merged_store_group::apply_stores): Test that bitregion_{start,end}
7319 is byte aligned, rather than requiring that start and width are
7320 byte aligned. Drop unnecessary struct keyword from
7321 struct store_immediate_info. Allocate and populate also mask array.
7322 Make start of the arrays relative to bitregion_start rather than
7323 start and size them according to bitregion_{end,start} difference.

7336 to pointer from reference, if NULL, don't push anything to it. Add
7337 first argument, use it to optimize skipping over orig stmts that
7338 are known to be before bitpos already. Simplify.
7339 (split_group): Return unsigned int count how many stores are or
7340 would be needed rather than a bool. Add allow_unaligned argument.
7341 Change split_stores argument from reference to pointer, if NULL,
7342 only do a dry run computing how many stores would be produced.
7343 Rewritten algorithm to use both alignment and misalign if
7344 !allow_unaligned and handle bitfield stores with gaps.
7345 (imm_store_chain_info::output_merged_store): Set start_byte_pos
7346 from bitregion_start instead of start. Compute allow_unaligned
7347 here, if true, do 2 split_group dry runs to compute which one
7348 produces fewer stores and prefer aligned if equal. Punt if
7349 new count is bigger or equal than original before emitting any
7350 statements, rather than during that. Remove no longer needed
7351 new_ssa_names tracking. Replace num_stmts with
7352 split_stores.length (). Use 32-bit stack allocated entries
7353 in split_stores auto_vec. Try to reuse original store lhs/rhs1
7354 if possible. Handle bitfields with gaps.
7355 (pass_store_merging::execute): Ignore bitsize == 0 stores.
7356 Compute bitregion_{start,end} for the stores and construct
7357 store_immediate_info with that. Formatting fixes.

34453 RS6000_BTI_bool_V16QI. Remove erroneous ALTIVEC_BUILTIN_VEC_CMPNE
34454 entry for overloaded function argument types RS6000_BTI_bool_V4SI
34455 andRS6000_BTI_bool_V4SI, mapping to P9V_BUILTIN_CMPNEB. Remove
34456 two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to
34457 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
34458 Power9 for implementations of vec_cmpne. Change the signature for
34459 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
34460 (representing vec_all_ne) to remove the previously described first
34461 argument of type RS6000_BTI_INTSI, as this was an artifact of
34462 reliance on the AltiVec predicate framework, which is no longer
34463 used in the implementation of these functions. Add
34464 P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq
34465 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
34466 since, unlike the AltiVec predicate framework implementation, we
34467 do not share function descriptors between vec_alle and vec_anyeq.
