5393 * stor-layout.c (update_alignment_for_field): Fix comment about
5394 KNOWN_ALIGN. For MS bitfields, if we start a new run, make sure
5395 we start it properly aligned.
5396 (place_field): At the beginning of a record, pass 0 as KNOWN_ALIGN
5397 to update_alignment_for_field, and recompute it afterwards using
5398 the alignment of the record.
5399 When a packed bitfield precedes an MS bitfield, don't add padding
5400 at the end of the packed bitfield on behalf of the base type of
5401 the packed bit field.
5402 Don't adjust rli->bitpos at the end
5403 of an MS bitfield run if we already adjusted bitpos/offset for an
5404 alignment as large or larger than the bitfield type size.
5405 Take possible record alignment > BIGGEST_ALIGNMENT into account
5406 when calculating actual_align.
5407 Only put packed buit fields into rli->prev_field if they end up
5409 Also set rli->remaining_in_alignment when we re-set rli->prev_field.
5410 Update rli->remaining_in_alignment when we have already started a
5411 run of bit fields and we process a packed bit field.
