Is GDB support for IPv6 useful?


Jan Kratochvil posted patches on the gdb-patches mailing list which add
support for both "target remote" connecting to IPv6 targets, and gdbserver
listening on IPv6 targets.

You can already simulate this behavior for GDB, by using "target remote |"
in combination with a helper like socat.  If support were added to gdbserver
for using arbitrary file descriptors - not hard, as you can see from Jan's
latest patch - it could do the same.

But what I'm really interested in is whether native IPv6 support would be
useful for GDB.  If it is, we should go ahead and merge it.  If no one or
almost no one is ever going to want it, then we shouldn't, and I can write
up some text for the manual about how to use an external program to
implement it.

I have never used IPv6, for debugging or anything else, so I don't feel able
to make a useful decision about this.  I'd like to hear from some people who
do use it.
