Ok, that appears to be more than "compile and go". Wouldn't the
generated code be more or less from templates with just a few changes to
point to parameters ?

In terms of the pre-compilers for the various SQL statements, it is said
that it generates GEM code, so I assume this needs to be changed to
generating LLVM code ?

Big picture: would those changes represent a HUGE amount of work ? I
realise that it prevents "compile and go", but just how involved is it
to update the on-the-fly code and the GEM to LLVM change ?
