That's pretty much it.

For Alpha, the configure script and makefiles appear to have been already
taken care of.

The easiest approach would be to look at other targets, and see how they work.
You needn't bother implementing those ops that correspond to TCG_TARGET_HAS_*
definitions (see */tcg-target.h), and it would probably be best to implement
TCG ops only with the tightest possible constraints at first (i.e. register
operands only for all ops except qemu_{ld,st}*).

tcg/README documents most of what you should need.
