Hi Slava,

we don't preserve LCSSA in the new PM. If you need it you have to rerun LCSAA before your pass.

Cheers, Philip

Hi,

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