Or maybe better scripts/smlp/..., if you are going to add some wrapper that runs the semantic patches on the source tree. Or something like that, a dedicated subdirectory to store the semantic patches in individual files. > What do you think the best way would be to introduce some check like this > in the build environment? I've only heard about the tool, I haven't used it yet. Does it need to preprocess and parse source files like sparse does, or can it check C files without expanding macros and includes? If the former, then let's extend make C=... to also support spatch. If the latter, then a script that runs spatch on all *.c files found the tree should be enough. But as I said, I haven't used the tool, so I don't know what it needs and what it can offer.
