Re: [PATCH] Dwarf2 missing location lists for VMS

The HP VMS Debug Team is willing take a look at implementing location
lists. I was asked to inquire if there is subset of expression

.debug_loc section. Are there more possible? Is it a waste of time to
try to come up with a complete subset?

DW_OP_breg*
DW_OP_reg*
DW_OP_piece

There are plenty more possible. The opcode language is probably Turing complete. Those are the ones you'd expect to see used solo, though.

I guess for now we should just assume one expression is
fine, but location lists aren't.  If more trouble appears,
we can deal with that (i.e. get it fixed ;-).
