[llvm-dev] darwin bootstrap failure

[Don Hinton via llvm-dev]

Hi Jack:

Looks like I missed this one in my recent change.

Please let me know if this solves your problem:

$ git diff
diff --git a/utils/TableGen/InfoByHwMode.cpp
b/utils/TableGen/InfoByHwMode.cpp

 }

 ValueTypeByHwMode llvm::getValueTypeByHwMode(Record *Rec,
                                              const CodeGenHwModes &CGH) {

thanks...
