Subject: made get_Block_cfgpred() and get_Block_n_cfgpreds() inline
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=eeeb88f4c5d929f2c05e452362c65bfc8d375ae3;p=libfirm

made get_Block_cfgpred() and get_Block_n_cfgpreds() inline
get_negated_pnc() now used the mode to supress unordered bit
on modes that do not have them.
