their true values listed despite execute_cfa_program extracting a 'how'

should it be?
Why isn't it? Please debug this, since reading the code clearly suggests it works as you expect. See dwarf2_frame_cache.
I know the PR register is
technically caller save, but has a CFI entry in my test program, but then
in practice PR is really treated as callee save anyway. Is that just a
special case?
I would need to see the CFI, sorry - I can't follow exactly what you mean.
