GlobalValueSummary (SummaryKind K, GVFlags Flags, std::vector< ValueInfo > Refs) | |
Global variable summary information to aid decisions and implementation of importing.
Global variable summary has two extra flag, telling if it is readonly or writeonly. Both readonly and writeonly variables can be optimized in the backed: readonly variables can be const-folded, while writeonly vars can be completely eliminated together with corresponding stores. We let both things happen by means of internalizing such variables after ThinLTO import.
