on x86_64, allmodconfig: $ gcc --version gcc (SUSE Linux) 7.5.0 $ sparse --version 0.6.2 I seem to be having some problems with kernel/time/timekeeping.c, including a segfault. a. Is it sparse that segfaults? b. what prints this message? make[3]: *** Deleting file 'kernel/time/timekeeping.o' c. I would prefer to be able to tell the source of warning/error messages, i.e., gcc or sparse. Especially when they are intermixed. So one solution IMO would be to be able to do a full sparse check _only_, without the gcc build. That way the messages would obviously be from sparse. Another reason to do that is that I often do gcc builds and then would like to follow that up with a sparse check build, but currently that means that I have to do the full gcc + sparse build, which is really time consuming since I have a wimpy laptop.
