Having said that the support for noreturn functions in objtool is not great. There have been talks about improving it but it needs to happen in cooperation with GCC because there is currently no way to know that GCC decided to place unreachable somewhere (decided that a function is noreturn). I do not know if there is a progress on this front behind the scenes.
Once we start building our enterprise kernels with GCC 13+, asking our performance team to evaluate the option -funreachable-traps might be worthwhile. -- You are receiving this mail because: You are on the CC list for the bug.
