Subject: Re: patch: dwarf handling of values spanning > 1 register

The concept is fine, but I do not like the idea of generating a
PARALLEL containing a bunch of REGs just to pass the relevant REGNOs
back to the caller.

I do this because we also have to get the right size for DW_OP_piece, that we get from the mode of the regno. So we need the mode, and the regno. We could have an array of structures, of two arrays (one for mode and one for regno), but that's too much work, and a PARALLEL works peachily.
