I don't have much knowledge of how gcc generates dwarf, but upon examination of the files in gcc, I had the impression that gcc never generates "location lists" (dwarf 2.0 section 2.4.6). It only generates "location expressions". Is that correct ?
Right now, I don't know if GCC ever generates location lists.  A patch
is awaiting review that makes GCC do it quite accurately; search for
"var tracking".

This patch was submitted months before stage3 (originally in one of the rtlopt merge branches), hopefully whoever takes a look at it will keep that in mind.
