Hi Andrew,
As Amit Kale mentioned in December, to support NPTL gdbserver needs to look
up symbols during remote_wait. The existing qSymbol model assumes that only
at objfile loads (i.e. during td_ta_new) do we need to look up symbols; NPTL
looks up symbols lazily when it needs them, which includes at the creation
of the first child thread. This patch (which, I know, needs a matching
change for the manual) allows qSymbol: queries as a response to remote_wait,
in much the same way as the file I/O protocol.
Is this OK? If so I'll write up the documentation change.
