I think this broke the build:

/home/espindola/llvm/llvm/lib/CodeGen/AsmPrinter/AsmPrinter.cpp: In
member function ‘virtual bool
llvm::AsmPrinter::doInitialization(llvm::Module&)’:
/home/espindola/llvm/llvm/lib/CodeGen/AsmPrinter/AsmPrinter.cpp:109:
error: ‘class llvm::Mangler’ has no member named ‘setUseQuotes’
/home/espindola/llvm/llvm/lib/CodeGen/AsmPrinter/AsmPrinter.cpp:112:
error: ‘class llvm::Mangler’ has no member named
‘setSymbolsCanStartWithDigit’
make[3]: *** [/home/espindola/llvm/llvm-build/lib/CodeGen/AsmPrinter/Debug/AsmPrinter.o]
Error 1
