[Qemu-devel] GDBstub system emulator breakage

[Blue Swirl]

Hi,

GDB support for system emulator is broken in the current CVS, execution 
never continues after a breakpoint.

Reversing some of the recent GDB patch re-enables system emulator debugging, 
but breaks user mode. This is what happens on startup:
qemu-sparc: undefined symbol: vm_start
