[llvm-dev] bug report on mem2reg

[liubaosen@tsinghua.edu.cn via llvm-dev]

Hi, all,

I think I found a bug on mem2reg in a particular case.
When I ran opt -mem2reg -basicaa -scalar-evolution -loops -da -analyze opts.ll, it collapsed. While without mem2reg option, it runs well. so I guess it has something to do with mem2reg.
The relative files have been affixed, please check them for me.
Thanks in advance.
