DW_OP_piece and DW_OP_bit_piece support

["Thomson, Patrick S" <patrick dot s dot thomson at intel dot com>]

Hi Folks,

I'm looking for a little guidance/help with DW_OP_piece. Basically I
need 
to support DW_OP_piece pretty soon and was going to hack a solution for 
local consumption until full piece support made its appearance in 6.5.
However,
I also need to support a variant of DW_OP_piece called DW_OP_bit_piece,
which 
would most likely make use of changes that are needed by piece. 

>From what I can ascertain from the code and previous email streams, the 
parts not implemented mostly deal with modifications for the value
structure to handle the data being in chunks. Does anyone know what
the proposed changes are? I'd like to be able write DW_OP_bit_piece 
such that it is compatible with the DW_OP_piece changes.

Thanks in advance!
