[LLVMdev] Build Failures

[David Greene]

I am getting -Werror failures building:

[off-opt]    : [llvm] /ptmp/dag/llvm/official/llvm/include/llvm/ADT/StringRef.h: In member function 'virtual llvm::AliasAnalysis::AliasResult {anonymous}::AliasAnalysisCounter::alias(const llvm::AliasAnalysis::Location&, const llvm::AliasAnalysis::Location&)':
[off-opt]    : [llvm] /ptmp/dag/llvm/official/llvm/include/llvm/ADT/StringRef.h:68:30: error: 'AliasString' may be used uninitialized in this function [-Werror=uninitialized]
[off-opt]    : [llvm] /ptmp/dag/llvm/official/llvm/lib/Analysis/AliasAnalysisCounter.cpp:130:15: note: 'AliasString' was declared here

[off-opt]    : [llvm] /ptmp/dag/llvm/official/llvm/lib/Target/X86/Disassembler/X86DisassemblerDecoder.c: In function 'decode':

Note that these have to be optimized builds as the use-before-def
warning doesn't kick in until gcc does dataflow analysis.
