From e846f0dc57f441e5e93194d39bc9b8ac2ab5e0a4 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Tue, 4 Jun 2019 15:42:48 +0300 Subject: kbuild: add support for ensuring headers are self-contained Sometimes it's useful to be able to explicitly ensure certain headers remain self-contained, i.e. that they are compilable as standalone units, by including and/or forward declaring everything they depend on. Add special target header-test-y where individual Makefiles can add headers to be tested if CONFIG_HEADER_TEST is enabled. This will generate a dummy C file per header that gets built as part of extra-y.
