Hi Ingo, Since commit f96eca432015ddc1b621632488ebc345bca06791 merged, the scripts/clang-tools/gen_compile_commands.py can't work very well. In this patch the build_policy.c and build_utility.c include kernel/sched/xxx.c( such as rt.c idle.c...), so it compile the build_utility.o build_policy.o directly, and it won't generate kernel/sched/xxx.c(such as rt.o idle.o), so the gen_compile_commands.py can't work. It will report "[8/23/2022, 3:24:06 PM] "rt.c" not found in "${workspaceFolder}/compile_commands.json". 'includePath' from c_cpp_properties.json in folder 'linux' will be used for this file instead.". And i test the kdump & crash tools, it can find the functions by line in kernel/sched/xxx.c( such as rt.c idle.c), it works well. I can't solve this report error, so i want to get help. Maybe we change the gen_compile_commands.py code can solve this problem or can we revert this change?(3.9% build wall time decrease really matter? it will destory all tool's parse result which depends on the compiled file result).
