[Bug gdb/9979] New: DW_OP_value not supported

[hubicka at gcc dot gnu dot org]

DW_OP_value would be very useful in GCC to output debug info for this pointers
of inlined methods where the actual address was optimized out.

Yeah -- but I don't think DW_OP_value is in any released standard.
I guess we could make DW_OP_GNU_value in the meantime, depending
on how urgent this is.

I think it's reasonable to take the value in the draft at this point;
it's marked as accepted, and while it could conceivably be backed out
(in fact it obsoleted an earlier extension to DWARF3), I don't think
it's likely.  My two cents.

According to jakub, these may be the values:

 DW_OP_implicit_value 0x9e
 DW_OP_stack_value 0x9f

Handy pointers:

http://www.dwarfstd.org/ShowIssue.php?issue=071227.1&type=closed3

Apparently DW_OP_value was renamed DW_OP_stack_value.
