This is the same approach that the language Jai (which Jonathan Blow is developing) is using: Fast-to-compile debug builds via hand-written x64 compiler, heavily optimized release builds via LLVM. This is why he was able to have ridiculously high-speed debug builds, and I think V is probably the same right now. I think J. Blow commented in one of his videos that he might be able to put some optimization on the x64 compiler (such as dataflow optimization) when the language is mostly complete. Although builds will be slower because of this, I still trust Blow that he will make a faster compiler than GCC/Clang, because the compiler will be specialized to its language rather than being all-purpose. (Also, C++ takes ridiculously lot to just parse everything, while Jai is must simpler to parse). Maybe V's developer will also work on some optimizations after the basic compiler's finished.
