russell@unturf.com bb1a6f002f diamond-scan: llvm/gcc/swift/webkit O(2^D) type hierarchy traversal ... swift-0001: QualifiedLookupRequest::evaluate (NameLookup.cpp:2860) pushes protocol superclassDecl onto BFS stack unconditionally — visited.insert() return not checked. Nearby ClassDecl arm (line 2833) is correctly guarded. Diamond protocol hierarchies sharing a class superclass trigger O(2^D) re-traversal on every qualified member lookup. Fix: check .second. llvm, gcc, webkit: CLEAN in available sparse-clone code.		2026-03-29 20:19:38 -04:00
