UniformityAnalysis offers all of the same features and much more, there is no reason left to use the legacy DAs. See RFC: https://discourse.llvm.org/t/rfc-deprecate-divergenceanalysis-legacydivergenceanalysis/69538 - Remove LegacyDivergenceAnalysis.h/.cpp - Remove DivergenceAnalysis.h/.cpp + Unit tests - Remove SyncDependenceAnalysis - it was not a real registered analysis and was only used by DAs - Remove/adjust references to the passes in the docs where applicable - Remove TTI hook associated with those passes. - Move tests to UniformityAnalysis folder. - Remove RUN lines for the DA, leave only the UA ones. - Some tests had to be adjusted/removed depending on how they used the legacy DAs.
