I have been in the compiler group at DEC for the last ten years.

VAX Fortran has always had its own code generator.
VAX Pascal V1.0 had its own.
VAX Pascal V2.0 and later had its own.
VAX C, VAX PL/I, and VAX Ada have always shared their code generator; although
these days they are very different versions of the base cg because the
different projects evolved in different ways.
VAX Cobol had its own, but I think it had common origins with VAX Fortran.
VAX Basic had its own.

The Mips compilers have used two different code generators, one based on the
one that came from Mips Co., and the other based on our new highly optimizing
GEM code generator technology

The Alpha compilers are all using the GEM technology.
