--- Comment #14 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Dunno, bet we really want to introduce CLOBBER(bol) and only consider bol a=
nd
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 perha=
ps
remove both as pair, etc.=
