Fix for Bug 3671 - QEMU GDB stub listens on IPv6-only port on Windows 7
The connection string used by the GDB stub does not specify which
version of the Internet Protocol should be used by the port on
which it listens. On host platforms with IPv6 support, such as
Windows 7, this means that the stub listens on an IPv6-only port.
Since the GDB client uses IPv4, this means that the client cannot
connect to QEMU.
TODO-list:
CPU common:
- Unimplemented features/bugs:
- Delay slot handling may fail sometimes (branch end of page, delay
slot next page)
- Atomical instructions
- CPU features should match real CPUs (also ASI selection)
- Optimizations/improvements:
- Condition code/branch handling like x86, also for FPU?
- Remove remaining explicit alignment checks
- Global register for regwptr, so that windowed registers can be
accessed directly
- Improve Sparc32plus addressing
- NPC/PC static optimisations (use JUMP_TB when possible)? (Is this
obsolete?)
- Synthetic instructions
- MMU model dependant on CPU model
- Select ASI helper at translation time (on V9 only if known)
- KQemu/KVM support for VM only
- Hardware breakpoint/watchpoint support
- Cache emulation mode
- Reverse-endian pages
- Faster FPU emulation
- Busy loop detection
