clang-tidy misreports progress when duplicating files due to multiple targets

[dkaszews]

Here is the log of clang-tidy progress when I run it on my repo, I edited paths to be relative and space-aligned first 9 items for readability.

[ 1/18] Processing file include/glug/detail/backport/type_traits.hpp.
[ 2/18] Processing file include/glug/filesystem.hpp.
[ 3/18] Processing file include/glug/filter.hpp.
[ 4/18] Processing file include/glug/glob.hpp.
[ 5/18] Processing file include/glug/regex.hpp.
[ 6/18] Processing file src/filesystem.cpp.
[ 7/18] Processing file src/filesystem.cpp.
[ 8/18] Processing file src/filter.cpp.
[ 9/18] Processing file src/filter.cpp.
[10/18] Processing file src/glob.cpp.
[11/18] Processing file src/glob.cpp.
[12/18] Processing file src/main.cpp.
[13/18] Processing file src/regex.cpp.
[14/18] Processing file src/regex.cpp.
[15/18] Processing file test/unit/main.cpp.
[16/18] Processing file test/unit/parametrized.hpp.
[17/18] Processing file test/unit/test_filesystem_explorer.cpp.
[18/18] Processing file test/unit/test_glob_decompose.cpp.
[19/18] Processing file test/unit/test_glob_filter.cpp.
[20/18] Processing file test/unit/test_glob_to_regex.cpp.
[21/18] Processing file test/unit/tree.cpp.
[22/18] Processing file test/unit/tree.hpp.

Note that all files in src/ except for main.cpp are analyzed twice. This is completely expected, as they appear twice in the compile_commands.json: once for the main executable, once for UT. What I would like to see fixed though is the [22/18] part, as it is confusing and misleading, it should instead read as [*/22], since that is the total number to analyse.

Environment:

• Invoked as: clang-tidy $(git ls-files **.hpp **.cpp)
• OS: Linux 6.16.10-arch1-1 #1 SMP PREEMPT_DYNAMIC Thu, 02 Oct 2025 19:26:36 +0000 x86_64 GNU/Linux
• LLVM: 20.1.8

Thanks for reporting this issue! I was able to reproduce this problem with clang-tidy built from main branch. Trying to fix it right now :)
