This is a followup from #2340, which adds a check to CI for clangd diagnostics. It is added to GCC because clang is the slower of the two linux runners right now.
The script itself spawns clangd and speaks Language Server Protocol to it. We open files, and clangd returns diagnostics (if any). This enables a fairly straightforward way of checking an arbitrary number of source files for warnings/errors.
Simply use
make clangd-diagnostics
to run the tool. The variablesCLANGD_DIAGNOSTIC_INSTANCES
andNUM_THREADS
control the parallelism.
