** Description changed: - This is not a requirement but it will make it easier to navigate the - code using language servers. Kernel has a script to generate this file. + BugLink: https://bugs.launchpad.net/bugs/2119438 + + SRU Justification [Impact] Other source code tagging utilities (such as gtags) index the whole code base. 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 does this - but requires compilation commands 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. + 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 build-info. + package compile_commands.json into linux-buildinfo package.
