Subject: bechordal: Remove impossible case from get_decisive_partner_regs().
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=a0ac9ed6a6136970bbcb5c68c64a8663355281e5;p=libfirm

bechordal: Remove impossible case from get_decisive_partner_regs().

o2 gets determined from o1, so o1 cannot be null.
