...oop/list of loops to verify to the function pass. Instead, I think it would be easier to create a loop pass for LCSSAVerification and make all loop passes preserve it. > > This way, when LPM would be verifying preserved analysis, it’ll run the LCSSA verification for the current loop as well (verifyAnalysis from the new pass). We can make it depend on the existing LCSSA pass, so that requiring this one would result in building LCSSA if it’s not built yet. The verification itself will be moved from the existing LCSSA pass’s verifyAnalysis to the new pass’s verifyAnalysis (or we can keep verification i...

Hi Nick I am not quite sure what you meant by verifier. I checked online documents and found that there is a function verifyAnalysis() in Pass but it is empty. So do you suggest implementing that function? If it is the case, what should I look while implementing that function? Or something else altogether?

I'm assuming you have a PassManager PM, in which case it would be 'PM.add(createVerifierPass());' w...

Have you tried running the verifier after ConditionProfile runs? Just add it to the pass manager to run right afterwards and see what it picks up.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, the second part of my work is to preserve the profiling information through all the transformation passes and make it available to the backend machinery. Attached is an example patch on how I plan to preserve the information for a given transformation pass. And now comes the question into place: whats the best way to attach the profile info

Hi All, I am trying to build llvm on AIX. I installed all the required packages including gcc, g++, etc ./configure also went fine. but i tried to run gmake, i got the following error: llvm[1]: Compiling MemoryBuffer.cpp for Release+Asserts build llvm[1]: Compiling MemoryObject.cpp for Release+Asserts build llvm[1]: Compiling Mutex.cpp for Release+Asserts build llvm[1]: Compiling Path.cpp for

Hi All, I am trying to write code for simple instrumentation. What I want to do is to insert a call to an external function for result of each conditional branch instruction. This external function simply print true or false based on the result of condition. The modified code is then written into new file. However when I try to link that file with another bitcode file (containing external
