* clang: install clang-scan-depsLexi Winter2025-07-061-0/+6
| | | | | | | | | | | | | | | | | | clang-scan-deps is used to generate dependency information from C++20 modules according to proposed standard ISO/IEC WG21 P1689R5[0]. It is required by common build tools (e.g., CMake) to build C++ sources that use modules. Since this is a core build tool, install it by default, not gated behind MK_CLANG_EXTRAS.

* Convert libllvm, libclang and liblldb into private shared librariesDimitry Andric2025-04-253-95/+163
| | | | | | | | | | | | | | | | | | | | This allows clang, lld, lldb, and other llvm tools to be linked against these shared libraries, which makes them smaller and avoids duplication. Since these are not quite the same as the shared libraries shipped by the upstream llvm build system, and we do not want to expose the ABI to external programs such as ports, make them private libraries. Note that during the cross-tools stage they are still built as static libraries, so the cross compiler and linker are static binaries, as they have always been. This also requires a depend-cleanup.sh kludge which will be added in a follow-up commit, to ensure binaries are rebuilt against the shared libraries in case of incremental builds.

* Partially revert 6527682ab705 for llvm-based projectsDimitry Andric2025-04-241-0/+1
| | | | | | | | | | Upstream llvm compiles most of their subprojects with -std=c++17 explicitly, not -std=gnu++17. In gnu++17 mode, both clang and gcc define the macro 'i386' on i386, which clashes with a namespace identifier in contrib/llvm-project/llvm/include/llvm/ExecutionEngine/JITLink/i386.h. Since the default after 6527682ab705 is now CXXSTD=gnu++17, explicitly set CXXSTD=c++17 for lib/clang, lib/libclang_rt and lib/libomp.
* libllvm: remove duplicated SRCS_MIN lineDimitry Andric2025-04-191-1/+0
| | | | | | | This is not harmful when making a static library apparently, but will result in duplicate symbol errors when making a dynamic library. MFC after: 3 days
* src: Use gnu++17 as the default C++ standardJohn Baldwin2025-04-111-1/+0
| | | | | | | | | | | | | | | | | | | | | | Previously the compiler's default C++ standard was used unlike C where bsd.sys.mk explicitly sets a default language version. Setting an explicit default version will give a more uniform experience across different compilers and compiler versions. gnu++17 was chosen to match the default C standard. It is well supported by a wide range of clang (5+) and GCC (9+) versions. gnu++17 is also the default C++ standard in recent versions of clang (16+) and GCC (11+). As a result, many of the explicit CXXSTD settings in Makefiles had the effect of lowering the C++ standard instead of raising it as was originally intended and are removed. Note that the remaining explicit CXXSTD settings for atf and liblutok explicitly lower the standard to C++11 due to use of the deprecated auto_ptr<> template which is removed in later versions.

* Adjust LLVM_ENABLE_ABI_BREAKING_CHECKS depending on NDEBUGDimitry Andric2024-10-241-0/+4
| | | | | | | | | | | | | | When assertions are disabled, the upstream build system disables LLVM_ENABLE_ABI_BREAKING_CHECKS by default. Though the upstream build system allows it to be force-enabled, it looks like that is not a well-tested build-time configuration. Therefore, always disable LLVM_ENABLE_ABI_BREAKING_CHECKS when assertions are disabled, which will also save some more runtime cost when people use WITHOUT_LLVM_ASSERTIONS.
