Partially revert 6527682ab705 for llvm-based projects

2025-04-24T14:36:40Z

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.

src: Use gnu++17 as the default C++ standard

2025-04-11T13:53:50Z

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.

arm64: Allow userspace to be built with PAC and BTI

2024-05-22T17:02:26Z

Add the WITH/WITHOUT_BRANCH_PROTECTION build flags. This can be used to enable the use of pointer authentication (FEAT_PAuth) and branch target identification (FEAT_BTI) in userspace. The kernel already handles both of these is userspace, we just need to enable it. Leave disabled for a short period for this to settle before enabling.
