Yes. We don't need c++ to bootstrap g++ or anything else in the base system. Once we build the compilers, we can build the c++ that's in the tree. > couldn't we install clang *without* C++ support and then do the following to > build it *with* C++ support: > > 1) use gcc to build a bootstrap gcc *with* C++ support > 2) use the bootstrap gcc to build clang I suppose you could do that, but I'm unsure how much that buys you...
