How about going with a toolchain directory for the base system only=2E It w= ould use shared files, and have subdirectories specific to clang, gcc, or o= ther compiling components or versions=2E This way it is both modular and or= ganized=2E For instance: /usr/toolchain/bin/, /usr/toolchain/sbin/, and /usr/toolchai= n/lib/ can be used for shared files=2E /usr/toolchain/clang/, /usr/toolchai= n/gcc/, etc, and their (lib, sbin, bin, include) subdirectories can be used= for specifically needed files=2E The old directories can be softlinked to = there=2E Any drastic changes can only be tried in the head branch=2E Port compilers= should definitely be left alone, by not using /usr/local/toolchain/* at al= l=2E Sat Jul 1 10:01:29 UTC 2017, David Chisnall <theraven at FreeBSD=2Eorg> wr= ote: >Debian does something like this, and it=E2=80=99s a huge pain to work wit= h=2E The problem is that toolchains are not self-contained >monolithic comp= onents (though gcc likes to pretend that they are)=2E For example, we want = gcc and clang to use the same >linker, the same C and C++ standard library = implementations, and the same system headers, irrespective of the compiler = >version=2E Things that actually are private to a compiler are in separate = directories (see /usr/lib/clang, for example)=2E Fri Jun 30 21:13:32 UTC 2017, Mark Millard <markmi at dsl-only=2Enet> wrot= e: >commonality helps with making ports and such easier >to support as an example=2E The types of systems are not >completely independent=2E =2E=2E=2E >Reorganizations are a big deal and do not happen >often=2E =2E=2E=2E >It is also messy for ports to organize things differently >than upstream does=2E
