[LLVMdev] Incorrect loop optimization when building the Linux kernel
...dbg !3991
.loopexit.loopexit: ; preds = %13
br label %.loopexit
.loopexit: ; preds = %.loopexit.loopexit, %6
%.0 = phi i1 [ true, %6 ], [ false, %.loopexit.loopexit ]
ret i1 %.0, !dbg !4004
}
Could anyone explain why this is unhappening and how to avoid it.
Thanks,
Chengyu
