Hi, I had a question about this as well. The documentation about writing a pass shows an example like what John wrote, calling a function pass within a module pass on a per function basis. However, if I code it that way, I still get the same error: opt: /x/jeffhao/llvm/llvm/include/llvm/PassAnalysisSupport.h:232: AnalysisType& llvm::Pass::getAnalysisID(const llvm::PassInfo*, llvm::Function&) [with AnalysisType = llvm::LoopInfo]: Assertion `ResultPass && "getAnalysis*() called on an analysis that was not " "'required' by...

Hi, I'm trying to use the function getAnalysis. This is the code I'm using : void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<LoopInfo>(); AU.setPreservesAll(); } virtual bool runOnModule(Module &M) { LoopInfo &LI = getAnalysis<LoopInfo>(); } I get following error when I try to run my pass : opt:

I'd like to get some runtime profile data on my code using LLVM. The various -insert-X-profiling passes seem to add the profiling instrumentation to the code, but how do I actually generate profiling output? It seems like utils/profile.pl can do this, but it uses profile_rt.so which doesn't exist. I can manually compile the runtime directory using make install-bytecode, but it

Hi, I've trying to test a pass with a C version of the 171.swim SPECfp benchmark. If I run llvm-gcc on the C files, I can generate a functioning executable. However, if I use llvm-gcc with -emit-llvm, then run lli on the resulting bitcode, I get the following error: lli: /x/jeffhao/llvm/llvm-2.4/lib/ExecutionEngine/JIT/JIT.cpp:467: void llvm::JIT::runJITOnFunction(llvm::Function*): Assertion `!isAlreadyCodeGenerating && "Error: Recursive compilation detected!"' failed. Anyone know how to fix this? Jeff

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
