the plug-in just starts qemu as a gdb server, the rest is standard Eclipse behviour.
but, as I said, my interest is limited to ARM, I have no experience with other QEMU architectures.

yes
it behaves exactly like the j-link gdb server or the openocd started as a gdb server. you load flash/ram via the gdb client, set breakpoints, single step, inspect sources, etc. like in any debug session.
and, on arm, you can also enable semihosting, so you can see the trace messages or even read/write files on the host (useful for unit tests, to leave the xml report).
if you want to play with it, you can use the beta version available from
http://gnuarmeclipse.sourceforge.net/updates-test
instructions on how to build the custom QEMU (required by the plug-in) are available from
http://gnuarmeclipse.livius.net/wiki/Main_Page#QEMU
when ready it is planned to provide binaries for QEMU, but currently it is work in progress.

Liviu
