gnu diff3: apply patch to committed src, rather than at build time

2022-11-19T19:10:48+00:00

This appears to be a leftover from the time we used a less-capable VCS.

build: remove the option to build gnugrep

2020-12-25T21:14:17+00:00

Unconditionally install bsdgrep as grep, bootstrap or not. Remove all
build glue and stop installing both gnugrep and libgnuregex now that
all consumers of the latter are gone.

Retire obsolete GDB 6.1.1

2020-12-15T17:44:19+00:00

GDB 6.1.1 was released in June 2004 and is long obsolete. It does not
support all of the architectures that FreeBSD does, and imposes
limitations on the FreeBSD kernel build, such as the continued use of
DWARF2 debugging information.

It was kept (in /usr/libexec/) only for use by crashinfo(8), which
extracts some basic information from a kernel core dump after a crash.
Crashinfo already prefers gdb from port/package if installed.

Future work may add kernel debug support to LLDB or find another path
for crashinfo's needs, but in any case we do not want to ship the
excessively outdated GDB in FreeBSD 13.

Do a sweep and remove most WARNS=6 settings

2020-10-01T01:10:51+00:00

Repeating the default WARNS here makes it slightly more difficult to
experiment with default WARNS changes, e.g. if we did something absolutely
bananas and introduced a WARNS=7 and wanted to try lifting the default to
that.

Drop most of them; there is one in the blake2 kernel module, but I suspect
it should be dropped -- the default WARNS in the rest of the build doesn't
currently apply to kernel modules, and I haven't put too much thought into
whether it makes sense to make it so.

build: provide a default WARNS for all in-tree builds

2020-09-18T17:17:46+00:00

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.

Remove now-unused GNU as build infrastructure

2020-06-07T13:53:23+00:00

Retire BINUTILS and BINUTILS_BOOTSTRAP options

2020-06-07T00:07:21+00:00

As of r361857 all BINUTILS options are disabled by default - ports
have been changed to depend on binutils if they require GNU as, and
all base system assembly files have been switched to use Clang's
integrated assembler.
