  | commit gcc-14-9841-g1e3312a25a7
  | Author: Martin Jambor <mjambor@suse.cz>
  | Date:   Mon Apr 8 18:53:23 2024 +0200

  |     ICF&SRA: Make ICF and SRA agree on padding
  |     
  |     PR 113359 shows that (at least with -fno-strict-aliasing) ICF can
  |     unify two functions which copy an aggregate type of the same size but
  |     then SRA, through its total scalarization, can copy the aggregate by
  |     pieces, skipping paddding, but the padding was not the same in the two
  |     original functions that ICF unified.
