llvm dev - Jul 2011 - [LLVMdev] Dynamic Optimization selection for individual functions

Hi All,
I am trying to write a machine learning algorithm that would predict a good
optimization to apply to a given function. I wanted to perform this by
modifying the list of optimizations applied by the FPPassManager based on
some dynamic data.
At present I was trying to do this by modifying the
FPPassManager::runOnFunction(Function) implementation. However this is
causing the following 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?
Thanks,
Sameer

May be you're emitting the function, at the end of compilation, multiple
times ?
