Unlike those happy few who are seeing thousands of visibility warnings, I get only one with gcc 4.3: lib/CodeGen/SelectionDAG/SelectionDAGBuild.cpp:3889: warning: ‘llvm::SDISelAsmOperandInfo’ declared with greater visibility than the type of its field ‘llvm::SDISelAsmOperandInfo::AssignedRegs’ Anyway know what this is about?
