GHC was not the first Haskell compiler, hbc was the main compiler at
some point, so I suspect they used hbc. There was also lazy ML which I

This isn't a question specific to ghc. In general, the process of
bootstrapping compilers and porting them to new platforms can be
described by T-diagrams. When I did a web search on T-diagrams the

Most certainly not. ;-) (Well, except that I asked where did GHC come
from, which is pretty GHC-specific.)

Expressiveness certainly makes it easier, but nothing (other than
sanity...) stops you from writing a Haskell compiler in, say, COBOL.
