* [LTO] Record whether LTOUnit splitting is enabled in indexTeresa Johnson2019-01-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Records in the module summary index whether the bitcode was compiled with the option necessary to enable splitting the LTO unit (e.g. -fsanitize=cfi, -fwhole-program-vtables, or -fsplit-lto-unit). The information is passed down to the ModuleSummaryIndex builder via a new module flag "EnableSplitLTOUnit", which is propagated onto a flag on the summary index. This is then used during the LTO link to check whether all linked summaries were built with the same value of this flag. If not, an error is issued when we detect a situation requiring whole program visibility of the class hierarchy. This is the case when both of the following conditions are met: 1) We are performing LowerTypeTests or Whole Program Devirtualization. 2) There are type tests or type checked loads in the code. Note I have also changed the ThinLTOBitcodeWriter to also gate the module splitting on the value of this flag.

* Fix thinlto cache key computation for cfi-icall.Evgeniy Stepanov2017-08-091-0/+55
Summary: Fixed PR33966. CFI code generation for users (not just callers) of a function depends on whether this function has a jumptable entry or not. This information needs to be encoded in of thinlto cache key. We filter the jumptable list against functions that are actually referenced in the current module.
