I like "ou of band" for this case. I just wanted

DW_CFA_val_* cases using the DW_OP_stack_value suffix, and some way
to keep the API fairly simple. So you suggest:
return 0, *ops = ops_mem -> "undefined"
return 0, *ops = NULL -> "same_value"
Yep. Although I would be fine with any *ops != NULL.
I admit to not be completely clear on why the caller is providing the
ops_mem array (or why it increased from 2 to 3 in this proposal). If it
is an optimization for memory use, could you let the user provide an
arbitrary length array (and reuse *nops also as input size)?
