--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
SRA has a limit on the size of structures decomposed and GCC does not have a
aggregate copy propagation pass but relies on SRA.
There's --param sra-max-scalarization-size-{Osize,Ospeed}
Being able to perform copy coalescing(!) for A = B when B dies at the
assignment and A becomes live without this limit and without decomposing
but from SRA analysis would be nice.
