-TODO in new NCG
-~~~~~~~~~~~~~~~
-
-- Are we being careful enough about narrowing those out-of-range CmmInts?
-
-- Register allocator:
-    - fixup code
-    - keep track of free stack slots
-
-    Optimisations:
-
-    - picking the assignment on entry to a block: better to defer this
-      until we know all the assignments.  In a loop, we should pick
-      the assignment from the looping jump (fixpointing?), so that any
-      fixup code ends up *outside* the loop.  Otherwise, we should
-      pick the assignment that results in the least fixup code.
-
-- splitting?

--- x86 ToDos
-
-- x86 genCCall needs to tack on the @size for stdcalls (might not be in the
-  foreignlabel).
-
-- x86: should really clean up that IMUL64 stuff, and tell the code gen about
-  Intel imul instructions.
-
-- x86: we're not careful enough about making sure that we only use
-  byte-addressable registers in byte instructions.  Should we do it this
-  way, or stick to using 32-bit registers everywhere?
-
-- Use SSE for floating point, optionally.
-
-------------------------------------------------------------------------------
--- Further optimisations:
-
-- We might be able to extend the scope of the inlining phase so it can
-  skip over more statements that don't affect the value of the inlined
-  expr.
