Hi Eli, I have tried that: static void registerMyPass(const PassManagerBuilder &, llvm::legacy::PassManagerBase &PM) { PM.add(new MyPass()); } static RegisterStandardPasses RegisterMyPass(PassManagerBuilder::EP_OptimizerLast, registerMyPass); It still couldn't find my pass.

..., Is there a way to register callback that runs before/after passes? PassTimingInfo seems to do a similar thing by calling PassInstrumentationCallbacks::registerBeforePassCallback / registerAfterPassCallback, but it is hard-wired with StandardInstrumentations class. Do we have something similar to RegisterStandardPasses, so custom callbacks can be added from somewhere outside LLVM?

Hello, I have written a pass for the IR and I can run it with opt -load lib/LLVMMyPass.so -mypass -myarguments -S -o output.ll < output.bc I have registered my pass with the following code: static RegisterPass<MyPass> X("mypass", "MyPass Pass (with getAnalysisUsage implemented)"); How do I include the same pass in the clang driver. I tried running the pass: clang

I think your plugin needs to do something to tell clang/llvm when to run the pass. I’ll try to look later when I’m back at a computer. You need to use RegisterStandardPasses to add it to the default pipeline automatically.

It sounds like you want to write a MachineFunctionPass as a plugin, and run it in the middle of the pass pipeline of an existing backend?  No, there isn't any support for that; RegisterStandardPasses only works on IR. -Eli -- Employee of Qualcomm Innovation Center, Inc.

Hello, I've looked around in the documentation, and I can't see anywhere where there is a backend plugin capability for LLVM. I'd like to be able to get the output of the instruction selector along with the LLVM IR, or perhaps instrument that. Is there any capability to have a backend plugin in LLVM at all? Perhaps what is necessary is to manually drive the backend from the

Extension points were a great addition to the PassManager infrastructure. I'm just starting to learn about the new PassManager and am reading Bekket McClane's great series about it. For a long time I've written passes and then hacked up PassManagerBuilder and friends to add it to the pipeline. Then extensions came along. Now I don't need to hack PassManagerBuilder directly but

Clang doesn’t support adding passes from the command line the way opt does. Opt has special parsing in opt.cpp for this that clang doesn’t have. I’m not sure what the correct way to do this is. I think your plugin needs to do something to tell clang/llvm when to run the pass. I’ll try to look later when I’m back at a computer. On Fri, Jan 12, 2018 at 7:00 PM 陳韋任 via llvm-dev <llvm-dev at

Hi, I have a module pass and I hope to use it to optimize a real-world program. I need LTO，and I have got LTO plugin. But How can I add my passes to LTO Pass. I can't find solution.
