broken Clang build

I'm seeing:

CGCall.cpp: In member function 'llvm::Value* clang::CodeGen::CodeGenFunction::EmitVAArg(llvm::Value*, clang::QualType)':
CGCall.cpp:1543: error: 'const class clang::ABIInfo' has no member named 'EmitVAArg'
make[4]: *** [/Volumes/Data/Users/kremenek/llvm/tools/clang/lib/CodeGen/Debug/CGCall.o] Error 1

Did someone forget to check in a change (i.e., to a header file)?

Fixed, sorry.
