[llvm-dev] right way for setting PreserveLCSSA with new pass manager

[Zakharin, Vyacheslav P via llvm-dev]

Hi,

mustPreserveAnalysisID(LCSSAID) cannot be used with the new pass manager, so what is the right way for querying it?  FunctionAnalysisManager::getCachedResult<LCSSAPass>(F) will not work, since LCSSAPass does not have a result.  Moreover, it is not an analysis :)

Thanks,
Slava
