9548 * gimple-ssa-store-merging.c: Include rtl.h and expr.h.
9549 (struct store_immediate_info): Add bitregion_start and bitregion_end
9550 fields.
9551 (store_immediate_info::store_immediate_info): Add brs and bre
9552 arguments and initialize bitregion_{start,end} from those.
9553 (struct merged_store_group): Add bitregion_start, bitregion_end,
9554 align_base and mask fields. Drop unnecessary struct keyword from
9555 struct store_immediate_info. Add do_merge method.
9556 (clear_bit_region_be): Use memset instead of loop storing zeros.
9557 (merged_store_group::do_merge): New method.
9558 (merged_store_group::merge_into): Use do_merge. Allow gaps in between
9559 stores as long as the surrounding bitregions have no gaps.
9560 (merged_store_group::merge_overlapping): Use do_merge.
9561 (merged_store_group::apply_stores): Test that bitregion_{start,end}
9562 is byte aligned, rather than requiring that start and width are
9563 byte aligned. Drop unnecessary struct keyword from
9564 struct store_immediate_info. Allocate and populate also mask array.
9565 Make start of the arrays relative to bitregion_start rather than
9566 start and size them according to bitregion_{end,start} difference.
9567 (struct imm_store_chain_info): Drop unnecessary struct keyword from
9568 struct store_immediate_info.
9569 (pass_store_merging::gate): Punt if BITS_PER_UNIT or CHAR_BIT is not 8.

9574 Formatting fixes.
9575 (struct split_store): Add orig non-static data member.
9576 (split_store::split_store): Initialize orig to false.
9577 (find_constituent_stmts): Return store_immediate_info *, non-NULL
9578 if there is exactly a single original stmt. Change stmts argument
9579 to pointer from reference, if NULL, don't push anything to it. Add
9580 first argument, use it to optimize skipping over orig stmts that
9581 are known to be before bitpos already. Simplify.
9582 (split_group): Return unsigned int count how many stores are or
9583 would be needed rather than a bool. Add allow_unaligned argument.
9584 Change split_stores argument from reference to pointer, if NULL,
9585 only do a dry run computing how many stores would be produced.
9586 Rewritten algorithm to use both alignment and misalign if
9587 !allow_unaligned and handle bitfield stores with gaps.
9588 (imm_store_chain_info::output_merged_store): Set start_byte_pos
9589 from bitregion_start instead of start. Compute allow_unaligned
9590 here, if true, do 2 split_group dry runs to compute which one
9591 produces fewer stores and prefer aligned if equal. Punt if
9592 new count is bigger or equal than original before emitting any
9593 statements, rather than during that. Remove no longer needed
9594 new_ssa_names tracking. Replace num_stmts with
9595 split_stores.length (). Use 32-bit stack allocated entries
9596 in split_stores auto_vec. Try to reuse original store lhs/rhs1
9597 if possible. Handle bitfields with gaps.
9598 (pass_store_merging::execute): Ignore bitsize == 0 stores.
9599 Compute bitregion_{start,end} for the stores and construct
9600 store_immediate_info with that. Formatting fixes.
