--- Comment #32 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Wed Feb 28 17:17:29 2018 New Revision: 258075 URL: https://gcc.gnu.org/viewcvs?rev=258075&root=gcc&view=rev Log: PR target/52991 * stor-layout.c (update_alignment_for_field): For targetm.ms_bitfield_layout_p (rli->t), if !is_bitfield && !DECL_PACKED (field), do the alignment update, just use only desired_align instead of MAX (type_align, desired_align) as the alignment. (place_field): Don't do known_align < desired_align handling early if targetm.ms_bitfield_layout_p (rli->t) and rli->prev_field is non-NULL, instead do it after rli->prev_field handling and only if not within a bitfield word. For DECL_PACKED (field) use type_align of BITS_PER_UNIT. * gcc.dg/bf-ms-layout.c: Revert 2012-04-26 changes. * gcc.dg/bf-ms-layout-2.c: Revert 2012-02-23 changes. * gcc.dg/bf-ms-layout-4.c: New test. * gcc.dg/bf-ms-layout-5.c: New test.
