bbi-36190.ll reproducer
llvm version: 039664db8
Reproduce with:
opt -disable-basicaa -loop-versioning bbi-36190.ll -S -o -
which gives
PHINode should have one entry for each predecessor of its parent basic block!
%d.1.lcssa.lver.orig = phi i16 [ undef, %for.body.lver.orig ], [ undef,
%for.end ]
in function f
LLVM ERROR: Broken function found, compilation aborted!
The input contains three blocks that are not reachable from entry:
for.body3: ; preds = %for.end
br label %for.cond4
for.cond4: ; preds = %for.cond4,
%for.body3
br i1 undef, label %for.cond4, label %for.end
for.end: ; preds = %for.cond4
br i1 undef, label %for.body3, label %for.inc
Wouldn't be surprised if that is what is causing confusion.
