Here, I use: $ make ARCH=i386 CF=-D__CHECK_ENDIAN__ CONFIG_DEBUG_SECTION_MISMATCH=y C=1 W=1 CHECK='compile_checks' M=drivers/media Where "compile_checks" is actually a small script that calls both smatch and sparse: #!/bin/bash /devel/smatch/smatch -p=kernel $@ /devel/sparse/sparse $@ So, I'm not sure why we need something else. That said, I didn't look on its code, but looking on its diffstat: Makefile | 23 +- scripts/Makefile.build | 4 +- scripts/runchecks | 734 ++++++++++++++++++++++++++- scripts/runchecks.cfg | 63 ++- scripts/runchecks_help.txt | 43 ++- Using a 734 lines python program just to do an exec on an external checker seems too much!
