* libcxxrt: allow build with gcc13 and --no-undefined-versionBrooks Davis2024-05-171-0/+10
| | | | | | | | | | GCC 13 supports _Float16 and __int128 on fewer architectures than clang and thus libcxxrt compiled with gcc13 is sometimes missing related symbols. Hack around this by explicitly appending --undefined-version to LDFLAGS in problematic cases. Reviewed by: theraven, dim Differential Revision: https://reviews.freebsd.org/D45233
* libcxxrt: align more with libc/MakefileBrooks Davis2024-04-221-2/+2
| | | | | | Use src.opts.mk instead of bsd.own.mk and define PACKAGE first. Fixes: da77a1b4f0dff libcxxrt: don't export nonexistant symbols
* libcxxrt: define SHLIBDIR before including bsd.own.mkDimitry Andric2024-04-221-1/+2
| | | | | | | | | | Otherwise bsd.own.mk overrides it, causing libcxxrt.so.1 to be erroneously installed into /usr/lib. Also add an ObsoleteFiles.inc entry, for removing the bad copy. Reported by: Josef 'Jeff' Sipek <jeffpc@josefsipek.net> Fixes: da77a1b4f0df
* libcxxrt: don't export nonexistant symbolsBrooks Davis2024-04-163-43/+384
| | | | | | | | | | | | | Remove version entries that we don't build. Add an arm specific Version.map and for other targets run the files through sed to handle int vs long in new and delete. Ideally we'd use the SYMBOL_MAPS functionality to preprocess with cpp, but it doesn't currently handle C++ symbols so be annoyingly duplicative for now.

* Standardize `-std=c++* as `CXXSTD`Enji Cooper2019-03-291-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* libcxxrt: Move mangled symbols out of extern "C++" in Version.mapEd Maste2018-01-231-28/+28
| | | | | | | | | | | | | | | | | | | | | r260553 added a number of mangled C++ symbols to Version.map inside of an existing `extern "C++"` block. ld.bfd 2.17.50 treats `extern "C++"` permissively and will match both mangled and demangled symbols against the strings in the version map block. ld.lld interprets `extern "C++"` strictly, and matches only demangled symbols. I believe lld's behaviour is correct. Contemporary versions of ld.bfd also behave as lld does, so move the mangled symbols out of the `extern "C++"` block.
