New Revision: 115110
URL: http://llvm.org/viewvc/llvm-project?rev=115110&view=rev
Log:
AnalyzerStatsChecker improvements:
- Use BlockEntrance rather than BlockEdge to bring in line with UnreachableCodeChecker. Fixes an issue where unreached blocks would still be counted as reachable.
- Added warnings for all BlockAborted locations. This allows us to see where the analyzer stopped analyzing.
