...ng error: "LLVM ERROR: 'main' label emitted multiple times to assembly file" I may be applying a few passes multiple times. Could anyone with an understanding of the PassManager shed some light on this?

...uctions in each function.), can anyone point me to a good way of doing that? If it is not already implemented do you think creating a feature Extraction pass and passing it as an optimisation pass would be the way to go?

Dear all, I am doing few experiments to do understand optimization phase interactions. Here is a brief description of my experiements. 1. I picked the list of machine independent optimizations acting on llvm IR (those that are enabled at O3). 2. for each optimzation in the optimization-list a) Compiled the program using 'clang -c O0 -flto program.c' b) opt
