Subject[PATCH 0/3] kbuild: clang-tidy
Date

I improved gen_compile_commands.py in the first two patches,
then rebased Nathan's v7 [1] on top of them.
To save time, I modified the Makefile part.
No change for run-clang-tools.py

I am not sure if the new directory, scripts/clang-tools/,
is worth creating only for 2 files, but I do not have
a strong opinion about it.

"make clang-tidy" should work in-tree build,
out-of-tree build (O=), and external module build (M=).
Tests and reviews are appreciated.

"make clang-tidy" worked for me.

masahiro@oscar:~/workspace/linux-kbuild$ make -j24 CC=clang clang-tidy
DESCEND objtool
CALL scripts/atomic/check-atomics.sh
CALL scripts/checksyscalls.sh
CHK include/generated/compile.h
GEN compile_commands.json
CHECK compile_commands.json

But "make clang-analyzer" just sprinkled the following error:

Error: no checks enabled.
USAGE: clang-tidy [options] <source0> [... <sourceN>]

I built clang-tidy from the latest source.
I had no idea how to make it work...

gen_compile_commands: parse only the first line of .*.cmd files
gen_compile_commands: wire up build rule to Makefile

Makefile: Add clang-tidy and static analyzer support to makefile
