[LLVMdev] a problem when using postDominatorTree
Hi all,
I'm using postDominatorTree to do some program analysis. My code works well for small tests, but when I run it on real applications, the following error occurs:
Inorder PostDominator Tree: DFSNumbers invalid: 0 slow queries.

[2] %bb1 {1,2}
[2] %bb {3,4}
[2] %entry {5,6}

[3] %bb7 {8,9}
[3] %bb2 {10,11}
[3] %bb6 {12,13}
