Import new (BSDL) device tree compiler. Now built by default, so that it can't be used on the host system (and not installed on the device, if required). The GPL'd one is still available if there are any devices that need it (make universe passes with it, including kernels that use fdt, but there may be some out-of-tree ones). WITH_GPL_DTC can be used to select the old one, for now. Probably won't be MFC'd, but we'll remove the GPL'd version in head after the new one has had a lot more testing and ship it in 10.0. 2013-01-22 17:49:51 +00:00			`# $FreeBSD$`

dtc(1): Revert WARNS change from r328173 WARNS > 3 breaks xtoolchain builds to varying degrees. Revert it. Reported by: lwhsu, jhb MFC after: 3 days 2018-01-31 22:20:33 +00:00			`WARNS?= 3`

Standardize `-std=c++* as `CXXSTD` CXXSTD was added as the C++ analogue to CSTD. CXXSTD defaults to `-std=c++11` with supporting compilers; `-std=gnu++98`, otherwise for older versions of g++. This change standardizes the CXXSTD variable, originally added to googletest.test.inc.mk as part of r345203. As part of this effort, convert all `CXXFLAGS+= -std=` calls to use `CXXSTD`. Notes: This value is not sanity checked in bsd.sys.mk, however, given the two most used C++ compilers on FreeBSD (clang++ and g++) support both modes, it is likely to work with both toolchains. This method will be refined in the future to support more variants of C++, as not all versions of clang++ and g++ (for instance) support C++14, C++17, etc. Any manual appending of `-std=` to `CXXFLAGS` should be replaced with CXXSTD. Example: Before this commit: ``` CXXFLAGS+= -std=c++14 ``` After this commit: ``` CXXSTD= c++14 ``` Reviewed by: asomers Approved by: emaste (mentor) MFC after: 1 month MFC with: r345203, r345704, r345705 Relnotes: yes Tested with: make tinderbox Differential Revision: https://reviews.freebsd.org/D19732 2019-03-29 18:45:27 +00:00			`CXXFLAGS+= -fno-rtti -fno-exceptions`

Rework CXXSTD setting via r345708 This change allows the user to once again override the C++ standard, restoring high-level pre-r345708 behavior. This also unbreaks building lib/ofed/libibnetdisc/Makefile with a non-C++11 capable compiler, e.g., g++ 4.2.1, as the library supported being built with older C++ standards.
