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. [1] <<exit node>> {0,21} [2] %bb1 {1,2} [2] %bb {3,4} [2] %entry {5,6} [2] %bb8 {7,20} [3] %bb7 {8,9} [3] %bb2 {10,11} [3] %bb6 {12,13} [3] %bb5 {14,19} [4] %bb4 {15,16} [4] %bb3 {17,18} 0 opt 0x085643e8 Stack dump: 0. Program arguments: opt -load=/home/a_i/llvm/llvm-2.7/Release/lib/ConsDumper.so -consdumper -f -o pbzip2_2s.bc pbzip2.bc -debug 1. Running pass 'dump constraints' on module 'pbzip2.bc'. Segmentation fault I have no hint about this. Does anyone know about the reason? Thanks a lot~ Regards, --Wenbin -------------- next part -------------- An HTML attachment was scrubbed...
