In LTOCodeGenerator.cpp there are some options related to optimization remarks. On MacOS, I can pass in this option to enable them: -Wl,-mllvm,-lto-pass-remarks-output=remarks But on Linux using 2.29.1 binutils version of gold, I try this alternative: -Wl,--plugin-opt,-lto-pass-remarks-output=remarks But I get this error message: LLVMgold: Unknown command line ar...

Hello all, In https://www.youtube.com/watch?v=qq0q1hfzidg, Adam Nemet (cc'ed) describes optimization remarks and some future plans for the project. I had a few follow-up questions: 1.

I've browsed the two patches and I think they're going to be exactly what I need. IIUC, the patches add two new LLVM instructions remark and note. These are inserted in the IL by the passes and the compiler emits them as diagnostic if the right -W flag is enabled? One question I have from the Clang patch. If I compile with -Weverything, will this enable all warnings *and* remarks? In this context, I only want to enable all remarks....

Hi, I would like to propose a new !annotation metadata kind that can be attached to arbitrary instructions to drive generating remarks that provide additional insight into transformations applied to a program. To motivate this, consider these specific questions we would like to get answered: * How many stores added for automatic variable initialization remain after optimizations? Where are they? * How many runtime checks inser...

Hi everyone, I frequently find that I want to quickly find out which functions have changed the most in size when I compile a program with one version of the compiler and another version of the compiler. Optimization remarks provide deeper insight into what the compiler does to individual functions during the compilation process. A tool based off of remarks would give us the means to say *exactly* what a pass did to a function during the compilation process. We also have remarks from the asm-printer which tell us the...

I would like to show a remark that would show call progress and appear on the CLI screen. The remark should be in the code of a sip [channel] or extentions [context] If I can't send my own remark, what little used 'show' command could I insert in the code?

Hi, I'm new to llvm and am trying to run benchmarks from the test-suite using lnt to check loop-vectorization for various benchmarks. Test are compiling and executing fine, but I am not getting optimization remarks while using flags like -Rpass-missed=loop-vectorize and -Rpass-analysis=loop-vectorize I've tried running it like this: lnt runtest test-suite --sandbox SANDBOX --cc /usr/local/bin/clang --test-suite ~/llvm_tests/llvm-test-suite/ --only-test SingleSource/UnitTests/Vectorizer/ --only-comp...

Hi all, I tried to poke my head into opt-report a while ago and didn't get very far. Now I'm looking at it again. I'm not sure I understand everything that's in place so my question here may be misguided. I'm trying to understand the way strings are handled. When a remark is emitted, it seems that the string is constructed on the fly based on streaming inputs. For example, ORE->emit([&]() { return OptimizationRemark(DEBUG_TYPE, "LoadElim", LI) << "load of type " << NV("Type", LI->getType()) <&l...

...39;s opt-report infrastructure. There are some things I'd like to be able to do with optimization reports that I don't think can be done, or at least aren't natural to do, with the current implementation. I understand that there is a lot of code in place already to produce optimization remarks, and one of my explicit goals is to minimize the amount of updating existing code while still enabling the new features I would like to support. I have some ideas in mind for how to achieve what I'm proposing, but I want to start out by just describing the desired results and if we can reach a...

Adam, thanks for all the suggestions! One nice aspect of the `-Rpass` family of options is that I can filter based on what I want. If I only want to see which inlines I missed, I could use `clang -Rpass-missed="inline"`, for example. On the other hand, optimization remark YAML always include remarks from all passes (as far as I can tell), which increases the amount of time it takes opt-viewer.py and other tools to parse. Would you be open to including options to, for example, only emit optimization remarks related to loop vectorization, or to not emit any analysis r...
