(Damn, I said i wouldn't be responding further...)

New code is adapted from Deparse. It processes the PCG in the normal way, but instead of (re)generating the Perl source code, it generates a LLVM IF "copy" of the PCG it is given. Let's call that the LLCG
This is the bit I don't currently get. take a piece of code like 
$m = ($s =~ /foo/);

Which is compiled to an optree that looks like: 

7  <@> leave[1 ref] vKP/REFC ->(end)
1     <0> enter ->2
2     <;> nextstate(main 1 p:3) v:{ ->3
6     <2> sassign vKS/2 ->7
4        </> match(/"foo"/) sKPS/RTIME ->5
-           <1> ex-rv2sv sK/1 ->4
3              <#> gvsv[*s] s ->4
-        <1> ex-rv2sv sKRM*/1 ->6
5           <#> gvsv[*m] s ->6

In general terms, what would the IR look like that you would convert that into?
