[llvm-dev] llvm pass is very slow

[Muhui Jiang via llvm-dev]

Hi

I write a LLVM function pass. The pass will loop the basicblock in the
function, check the instruction's type with dyn_cast<switchinst>, print the
instruction and the basicblock's successors. I think it is not very complex.

My bitcode file is about 30M. My CPU is i7-7700(3.6GHz). It has been
running for 60 hours but it is still running. I am not sure whether this is
a normal behavior. If so, any options or suggestions to help me speed up
the analysis. Many Thanks

Regards
Muhui
