- rGc0f87e83820b: [libc++] Remove _LIBCPP_HAS_NO_SPACESHIP_OPERATOR
I do wonder if CI is really going to be green. After all, it's not just that the lexer must support <=>, but we rely on the conforming behavior of =default, and synthesized candidates, and so on. But if you're really sure that all supported compilers do all that stuff, then sure, go for it.
Ping on D110738, btw. ;)
