Subject: [PATCH v3 00/10] kbuild: clang-tidy
Date: Sat, 22 Aug 2020 23:56:08 +0900	[thread overview]
Message-ID: <20200822145618.1222514-1-masahiroy@kernel.org> (raw)

I improved gen_compile_commands.py,
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

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

V3:
Fix minor mistakes pointed out by Nick
Add a new patch (09/10) to remove the warning about
too few .cmd files.

V2:
Keep the previous work-flow.
You can still manually run scripts/gen_compile_commands.json

'make compile_commands.json' or 'make clang-tidy' is handier
for most cases. As Nick noted, there is 3 % loss of the coverage.

If you need the full compilation database that covers all the
compiled C files, please run the script manually.
