[LLVMdev] MemoryDependenceAnalysis in ModulePass

[Jeff Yeong-Peng Hao]

Hi,

I'm having some trouble using the MemoryDependenceAnalysis pass within  
a ModulePass.  If I use addRequired and getAnalysis, it works properly  
within a FunctionPass, but opt aborts when I try to do the same in a  
ModulePass, with the following error:

opt: /x/jeffhao/llvm/llvm/include/llvm/Target/TargetData.h:114:  
llvm::TargetData::TargetData(): Assertion '0 && "ERROR: Bad TargetData  
ctor used.  " "Tool did not specify a TargetData to use?"' failed.

Has anyone else seen this error and know a way around it?

Thanks,
Jeff
