> Only to hit another issue:

There are many missing checks for rs6000_gen_cell_microcode now. :(.  I had
audit this code at one point and fixed all the issues but this was when I
submitted the patch for rs6000_gen_cell_microcode and nobody kept this working.
 I don't enough about cell any more to do the work and really I don't have time
to do it either.

(In reply to #c3)
That is because the patch in #c1 is incorrect.

Mine.
