3 # meta-clang (C/C++ frontend and LLVM compiler backend)
6 C/C++ compiler for OpenEmbedded/Yocto Project based distributions. This can cohabit
7 with GNU compiler and can be used for specific recipes or full system compiler.
38 Note that by default gcc will remain the system compiler, however if you wish
39 clang to be the default compiler then set
45 in `local.conf`, this would now switch default cross-compiler to be clang
60 compiler, switching to use LLVM runtime is done via a config metadata knob
69 Please note that this will still use crt files from GNU compiler always, while llvm now
95 Clang based cross compiler is not included into the generated SDK using `bitbake meta-toolchain` or
