[llvm-commits] Patch, enable reusing a module pass manager across multiple modules

[Pedro Artigas]

Hello All,

The patch below is intended to enable reusing a module pass manager across multiple modules, the core idea is that module passes do not have to be reallocated but are just initialized and finalized before/after each run so that the allocated state can be persistent across multiple modules

patch attached

Thanks

Pedro Artigas
