Repetitive entries in Analyzer reports

[jenetscaria-mcw]

I have build my project with clang 19.1.3 version and ran the ClangBuildAnalyzer for the same and I am observing repetitive entries for compiler frontend. Is there a reason for it to show repetition in object files.

Hard to know why that would be happening, without knowing more details.

Are you building for multiple architectures by chance (e.g. Apple "Universal" binaries for both arm64 and x64)?

Hi @aras-p, thank you for the reply. We have build clang from source but only for one target without any cross compilation, i.e. Clang target = x86 in windows x64 machine.

I am attaching a spreadsheet where we have extracted the total frontend and backend timings along with the compiler frontend and backend files from our ClangBuildAnalyzer report for your reference. The repetitive entries are highlighted with blue.

@jenetscaria-mcw I can't access the linked google sheet, permissions/sharing issue?

@aras-p , sorry forgot about the access, here's the excel file for the same

Ok but that still does not help in any way to know why it happened. The way ClangBuildAnalyzer works, is it tries to find all .json files under the build directory, checks which ones look like they are output by clang -ftime-trace, and aggregates info from them. So to understand why there are duplicates, I'd need a gather of all .json files under the directory that you use ClangBuildAnalyzer on.

Here is a zip of all the json files generated under my build directory for your reference.

@jenetscaria-mcw is that with the folder structure intact? I can see there are e.g. 16 files named get-model.cpp.json, but inside the zip file they all are under "root folder", and so they can't be properly unpacked.

My wild guess at this point would be that either you have some symbolic links under your build folder that point to the same folder several times, or that somehow under your build folder you ended up with json files from multiple builds, and now ClangBuildAnalyzer analyzes all of them.

output_json_files.zip
@aras-p, This will be the zip with all json files in the exact sub directories, there are multiple json files with the names but all correspond to different examples.

@jenetscaria-mcw running ClangBuildAnalyzer on these json files does not result in any duplicate entries, as far as I can tell.

I am getting duplicate entries still. Attaching a result file generated from ClangBuildAnalyzer for your reference.
