...a machine function pass to run with llc. But I get this error while building: "/home/erdem/llvm/lib/CodeGen/CodeGen.cpp:80: error: undefined reference to 'llvm::initializeNoopInserterPass(llvm::PassRegistry&)'" NoopInserter is the name of my pass. I already added this line to InitializePasses.h: "void initializeNoopInserterPass(PassRegistry&);". Can anyone tell me what the problem is?

I had INITIALIZE_PASS_BEGIN and INITIALIZE_PASS_END macros. I replaced them with INITIALIZE_PASS but I get the same error. If I understand correctly, I need to modify Passes.h, InitializePasses.h, and Codegen.cpp files to register my pass, right? Another question is: Is it necessary to have the createNoopInserterPass function? Erdem -------------- next part -------------- An HTML attachment was scrubbed...

This seems to be what I am looking for. That was very helpful. Thank you. Erdem From: vlknkls at gmail.com Date: Wed, 16 Sep 2015 16:25:29 +0000 Subject: Re: [llvm-dev] How to add NOP?

I ran cmake to build the visual studio projects. Then I included my code under the Visual Studio interface, but I placed my code separate from the CodeGen code. Visual studio was smart enough to compile and link in my code into the CodeGen library. Thus, I did not need to add my code into the same directory as the CodeGen files, and I did not need to change the CMakeList.txt. The offical name is

...on about this offline, and he pointed out to me that we could make this API work if we had statically declared pass dependency information (that must be guaranteed to be a superset of the true dynamic dependencies). If we have that information, then the createPass() methods can be made to call the initializePass(), which can in turn recursively initialize its potential dependencies. I'm putting my current patch (implementing the old version of this proposal) on hold to evaluate the possibility of going this route instead. --Owen -------------- next part -------------- An HTML attachment was scrubbed....

...e, lib/Transforms/Scalar/IndVarSimplify.cpp for examples of how to initialize, e.g. having "INITIALIZE_PASS_DEPENDENCY(LoopInfo)" sandwiched between BEGIN and END. Note that you'll want a forward declaration of initializeTestMPPass(), as it won't have a declaration in include/llvm/InitializePasses.h. These are all the changes I think I had to make to port my passes to 2.9 from 2.8.
