We can allocate space in numbering for vendor extensions.
What happens when you compile two sources with two different compilers
and they
use the same number for vendor extension?
What happens when another compiler uses 0x4104 TAG value for
something else and GCC uses it for DW_TAG_GNU_BINCL ?
You just end up with weird results
in the IDE or performance analysis program.
Also what happens after you fill up the vendor extension range?
What happens when vendor extension range for TAGs and Attributes are full ?
Also what happens when you change your compiler but not IDE, but you
don't
want to update the IDE?
What happens when GCC adds new DWARF extension but you do not want
to update GDB ?
