I got numerous warnings when building rsync on IA64 (Itanium-2) using Intel C/C++ compiler (see attached). Is this expected?

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 arg...

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. As an example of future work to be done, the talk mentions expanding the set of optimization passes that emit remarks. However, the Clang User Manual mentions that "optimization remarks do not really make sense outside...

I want to know all the optimization applied by the passes. I found two options in clang 1. -fsave-optimization-record 2. -Rpass-analysis=... However, they have nothing to do with the interaction btw IR files(.ll) Is there any tool that records all optimizations on IR file? -------------- next part -------------- An HTML attachment was scrubbed...

...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. In fact, I want to enable a family of remarks: the optimization remarks. There will be other modifiers to these remarks as well: 1. Report *missed* optimizations, instead of the successful ones. 2. Increase verbosity of the report. This...

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 insert...

Dear llvm-dev community, I am trying to analyze the optimization remarks generated through clang using -fsave-optimization-remark with -O3. --- !Analysis Pass: loop-vectorize Name: CFGNotUnderstood DebugLoc: { File: c-ray-mt.c, Line: 177, Column: 2 } Function: main Args: - String: 'loop not vectorized: ' - String: loop control flow is not understood by vectoriz...

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 n...

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? Can this be done? -- Larry Alkoff N2LA - Austin TX Using Thunderbird on Linux

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-compi...

...lear how and when these are constructed. What I'm wondering is whether it would make sense to introduce a sort of message catalog, similar to the way diagnostics are handled in clang (which I must admit I also have only a partial understanding of). It seems like the RemarkName for optimization remarks somewhat serves as a unique identifier (?) but I would think an integer value of some sort would be better, so maybe I'm misunderstanding what RemarkName is being used for. I'm imagining something that would end up looking like this: ORE->emit([&]() { return OptimizationRemark...

...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...

Hello all, During the compilation process, LLVM automatically derives various attributes about functions and values (for example that a pointer is nonnull, a function is constant, etc) that are used within a translation unit. I propose adding a pass to LLVM that allows front-ends to output derived attributes. Such a pass would be useful both for developers and end users to debug programs,

..., 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 remarks? Or is it important t...
