--- Comment #14 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Dunno, bet we really want to introduce CLOBBER(bol) and only consider bol and
eol clobbers for the stack reuse (or e.g. the tree-ssa-live.cc *live_vars*
handling).
Wonder what amount of work it would be to add that, I guess main thing will be
what to DCE etc., if we have CLOBBER(bol) followed by normal CLOBBER with no
aliasing stores in between, bet we must keep the former, if we have CLOBBER(bol
followed by CLOBBER(eol) with no aliasing stores in between, we could perhaps
remove both as pair, etc.
