When profiling a no-op incremental link of Chromium I found that the functions computeImportForFunction and computeDeadSymbols were consuming roughly 10% of the profile. The goal of this change is to improve the performance of those functions by changing the map lookups that they were previously doing into pointer dereferences. This is achieved by changing the ValueInfo data structure to be a pointer to an element of the global value map owned by ModuleSummaryIndex, and changing reference lists in the GlobalValueSummary to hold ValueInfos instead of GUIDs. This means that a ValueInfo will take a client directly to the summary list for a given GUID. Differential Revision: https://reviews.llvm.org/D32471 llvm-svn: 302108 |
