The LLVM Project is a collection of modular and reusable compiler and
toolchain technologies.
This port includes Clang (a C/C++/Objective-C compiler), LLD (a linker),
LLDB (a debugger), an OpenMP runtime library, and the LLVM infrastructure
these are built on.
===> The following configuration options are available for llvm17-17.0.6_7:
BE_AMDGPU=on: AMD GPU backend (required by mesa)
BE_WASM=on: WebAssembly backend (required by firefox via wasi)
CLANG=on: Build clang
COMPILER_RT=on: Sanitizer libraries
DOCS=on: Build and/or install documentation
EXTRAS=on: Extra clang tools
FLANG=off: Flang FORTRAN compiler
GOLD=on: Build the LLVM Gold plugin for LTO
LIT=on: Install lit and FileCheck test tools
LLD=on: Install lld, the LLVM linker
LLDB=on: Install lldb, the LLVM debugger
MLIR=on: Multi-Level Intermediate Representation
OPENMP=on: Install libomp, the LLVM OpenMP runtime library
POLLY=on: Polyhedral loop and data-locality optimizer
PYCLANG=on: Install python bindings to libclang
STATIC_LIBS=on: Install static libraries (does not effect sanitizers)
====> Options available for the single BACKENDS: you have to select exactly one of them
BE_FREEBSD=off: Backends for FreeBSD architectures
BE_NATIVE=off: Backend(s) for this architecture (X86)
BE_STANDARD=on: All non-experimental backends
===> Use 'make config' to modify these settings
devel/llvm17: fix build with libc++ 19
As noted in the libc++ 19 release notes [1], std::char_traits<> is now
only provided for char, char8_t, char16_t, char32_t and wchar_t, and any
instantiation for other types will fail.
This causes devel/llvm17 to fail to compile with clang 19 and libc++
19, resulting in errors similar to:
/usr/include/c++/v1/string:820:42: error: implicit instantiation of
undefined template 'std::char_traits<unsigned char>'
820 | static_assert(is_same<_CharT, typename
traits_type::char_type>::value,
