:-) Note that his patch does convert the m68k to RTL
prologue/epilogues. How many more textual prologue/epilogue targets
are left after this patch?

Far from a rewrite. It really doesn't hit the code generation stuff all
that hard. There's a ton of configury fixes/cleanups some codegen
tweaks, rtl prologues/epilogues, significant address mode changes
some call/return changes, etc. But it's really not huge relative to
the size of the m68k port.
