<pre>Noticed that the IR below assert in the hot/cold split pass.
; opt -passes=hotcoldsplit -S assert.ll
define void @foo(i32 %cond) {
entry:
%tobool = icmp eq i32 %cond, 0
br i1 %tobool, label %if.end, label %coldbb
coldbb:
call void (...) @sink()
br i1 undef, label %if.end, label %coldbb2
coldbb2:
br label %if.end
if.end:
%p = phi i32 [0, %entry], [1, %coldbb], [3, %coldbb2]
ret void
}
declare void @sink(...) cold</pre>
