The current default is provided in various Makefile.inc in some top-level directories and covers a good portion of the tree, but doesn't cover parts of the build a little deeper (e.g. libcasper). Provide a default in src.sys.mk and set WARNS to it in bsd.sys.mk if that variable is defined. This lets us relatively cleanly provide a default WARNS no matter where you're building in the src tree without breaking things outside of the tree. Crunchgen has been updated as a bootstrap tool to work on this change because it needs r365605 at a minimum to succeed. The cleanup necessary to successfully walk over this change on WITHOUT_CLEAN builds has been added. There is a supplemental project to this to list all of the warnings that are encountered when the environment has WARNS=6 NO_WERROR=yes: https://warns.kevans.dev -- this project will hopefully eventually go away in favor of CI doing a much better job than it.

# Our current make(1)-based approach to dependency tracking cannot cope with
|
|
# certain source tree changes, including:
|
|
# - removing source files
|
|
# - replacing generated files with files committed to the tree
|
|
# - changing file extensions (e.g. a C source file rewritten in C++)
|
|
#
|
|
# We handle those cases here in an ad-hoc fashion by looking for the known-
|
|
# bad case in the main .depend file, and if found deleting all of the related
|
|
# .depend files (including for example the lib32 version).
|
|
#
|
|
# These tests increase the build time (albeit by a small amount), so they
|
|
# should be removed once enough time has passed and it is extremely unlikely
|
|
# anyone would try a NO_CLEAN build against an object tree from before the
|
|
# related change. One year should be sufficient.
