This would be *very* nice: when I was at Thinking Machines I worked on
a High Performance Fortran (HPF) compiler that did this: we performed
many parallelizing optimizations over the AST coming out of the HPF FE
and generated code in Fortran 90 which was compiled by the platform's
native F90 compiler (the idea here being that the vendor (SGI or Sun)
would be able to write a better code generator for their CPUs than we
could). Anyway, this resulted in a very configurable and highly
maintainable optimizer that made it easy to try different
optimizations during development).
