However, in practice quite a bit of code base is disabled (either through macro definitions or makefiles where some sources are kept out of compilation). When inspecting a crash on certain architecture, it would help a lot to search thought only the active source code. Language servers [2] does this but requires compilation commands [1] to parse the code exactly as it was compiled. Linux has a script to generate compile_commands.json but it is not used by our builds. Users can build the sources themselves and generate this file. However, this requires compilation first and it takes quite a bit of time. Since we already compile the code, it takes at most a couple seconds more to generate this file. [Fix] After compilation run scripts/clang-tools/gen_compile_commands.py and package compile_commands.json into linux-buildinfo package. [Test Case] Build tested. Compile commands are compressed and included in the linux-buildinfo package [3]. $ dpkg --contents linux-buildinfo-6.14.0-24-generic_6.14.0-24.24_amd64.deb drwxr-xr-x root/root 0 2025-08-01 18:14 ./ drwxr-xr-x root/root 0 2025-08-01 18:14 ./usr/ drwxr-xr-x root/root 0 2025-08-01 18:10 ./usr/lib/ drwxr-xr-x root/root 0 2025-08-01 18:10 ./usr/lib/linux/ drwxr-xr-x root/root 0 2025-08-01 18:11 ./usr/lib/linux/6.14.0-24-generic/ -rw-r--r-- root/root 2373194 2025-08-01 18:10 ./usr/lib/linux/6.14.0-24-generic/abi -rw-r--r-- root/root 21582 2025-08-01 18:10 ./usr/lib/linux/6.14.0-24-generic/canonical-certs.pem -rw-r--r-- root/root 38606 2025-08-01 18:10 ./usr/lib/linux/6.14.0-24-generic/canonical-revoked-certs.pem -rw-r--r-- root/root 889358 2025-08-01 18:11 ./usr/lib/linux/6.14.0-24-generic/compile_commands.tgz -rw-r--r-- root/root 38 2025-08-01 18:10 ./usr/lib/linux/6.14.0-24-generic/compiler -rw-r--r-- root/root 296789 2025-08-01 18:10 ./usr/lib/linux/6.14.0-24-generic/config -rw-r--r-- root/root 96802 2025-08-01 18:10 ./usr/lib/linux/6.14.0-24-generic/fwinfo -rw-r--r-- root/root 0 2025-08-01 18:10 ./usr/lib/linux/6.14.0-24-generic/fwinfo.builtin -rw-r--r-- root/root 77077 2025-08-01 18:10 ./usr/lib/linux/6.14.0-24-generic/modules -rw-r--r-- root/root 3065 2025-08-01 18:10 ./usr/lib/linux/6.14.0-24-generic/modules.builtin -rw-r--r-- root/root 2131941 2025-08-01 18:10 ./usr/lib/linux/6.14.0-24-generic/sources drwxr-xr-x root/root 0 2025-08-01 18:14 ./usr/share/ drwxr-xr-x root/root 0 2025-08-01 18:14 ./usr/share/doc/ drwxr-xr-x root/root 0 2025-08-01 18:14 ./usr/share/doc/linux-buildinfo-6.14.0-24-generic/ -rw-r--r-- root/root 317265 2025-08-01 18:14 ./usr/share/doc/linux-buildinfo-6.14.0-24-generic/changelog.Debian.gz -rw-r--r-- root/root 1292 2025-08-01 17:08 ./usr/share/doc/linux-buildinfo-6.14.0-24-generic/copyright [Where things could go wrong] Package may fail to build.
