On: QBE vs. LLVM

[fefe23]

I would love to have a way to bootstrap LLVM. This looks promising but I'm guessing a C++ frontend is much more challenging than writing this backend.

gcc used to be the missing link, but they switched to C++ and now you can't bootstrap it with something like tcc.

Can't you still bootstrap LLVM from GCC, and GCC from the last C version, and that from tcc?

GNU GUIX works on the boostraping issue, they strive to reduce the seed size as much as possible: https://guix.gnu.org/blog/tags/bootstrapping/
