I’m trying to integrate clang-tidy in our build system. So far I’ve been using the CMake way.
The problem is that this introduces a ~1.7x build slowdown.
However, digging in the clang-tidy source code I noticed there’s a way to use it as a clang plugin.
This should significantly reduce the overhead, since there’s no need to parse the input files twice (once for clang-tidy and once for clang itself).
However, when I try to run it as a plugin, clang-tidy works fine but clang stops emitting any output:
$ ./bin/clang \ -fplugin=./lib/libclangTidyPlugin.so.12 \ -Xclang -plugin -Xclang clang-tidy \ -S \ -o test \ test.c test.c:2:7: warning: invalid case style for variable 'a' [readability-identifier-naming] int a; ^ A 1 warning generated.
I get a clang-tidy warning, but no assembly.
Is this expected?
Any suggestion on where to look to circumvent this issue?
