FreeBench/mason has a basic block that looks like this:
%tmp.130 = seteq int %p.0__, 5 ; <bool> [#uses=1]
%tmp.134 = seteq int %p.1__, 6 ; <bool> [#uses=1]
%tmp.139 = seteq int %p.2__, 12 ; <bool> [#uses=1]
%tmp.144 = seteq int %p.3__, 13 ; <bool> [#uses=1]
%tmp.149 = seteq int %p.4__, 14 ; <bool> [#uses=1]
%tmp.154 = seteq int %p.5__, 15 ; <bool> [#uses=1]
%bothcond = and bool %tmp.134, %tmp.130 ; <bool> [#uses=1]
%bothcond123 = and bool %bothcond, %tmp.139 ; <bool>
%bothcond124 = and bool %bothcond123, %tmp.144 ; <bool>
%bothcond125 = and bool %bothcond124, %tmp.149 ; <bool>
%bothcond126 = and bool %bothcond125, %tmp.154 ; <bool>
br bool %bothcond126, label %shortcirc_next.5, label %else.0
This is a particularly important case where handling CRs better will help.
