Towards the goal of getting `ninja libc-lint` back to green, fix the numerous instances of: warning: header guard does not follow preferred style [llvm-header-guard] This is because many of our header guards start with `__LLVM` rather than `LLVM`. To filter just these warnings: $ ninja -k2000 libc-lint 2>&1 | grep llvm-header-guard To automatically apply fixits: $ find libc/src libc/include libc/test -name \*.h | \ xargs -n1 -I {} clang-tidy {} -p build/compile_commands.json \ -checks='-*,llvm-header-guard' --fix --quiet Some manual cleanup is still necessary as headers that were missing header guards outright will have them inserted before the license block (we prefer them after).
