qSymbol when using symbol-file

["catalin.udma@freescale.com" <catalin.udma@freescale.com>]

Hi,

In the gdb/gdbserver scenario, gdb is not sending qSymbol packet when using "symbol-file", without "file" or "exec-file".
The steps are:
  start gdb (with no arguments)
  (gdb) symbol-file <file>
  (gdb) target remote <ip>:<port>
  ->  qSymbol packet is not sent.

If the "file" command  is used instead of "symbol-file", the qSymbol packet is sent to gdbserver.

The question makes more sense in the following context: Using Eclipse and DSF -GDB Hardware Debugging . Here, Eclipse is not using "file", but only "symbol-file" ( as explained why here: [1] ).  This  makes qSymbol notification not working. 

My questions/comments:
- In the above scenario, does make sense to enable qSymbol notification even when the exec-file is not specified? Here is not required to specify the  exec file. Or even in the gdb/gdbserver scenario where the application/executable is started by gdbserver on target.

- For the particular case when some symbol files are added after "target remote", gdb is sending qSymbol, even without having the exec file specified.  The above proposal would be in sync with this.

- What would be your other thoughts to fix the qSymbol for the gdb + Eclipse with DSF GDB Hardware Debugging scenario ?

Catalin
