[Qemu-devel] [PATCH] Handle debug signals on PowerPC

Hi,

The attached patch allows PowerPC QEMU to be used with the debugger.

Currently, any attempt to debug causes an unknown exception error. Note 
that there are also a few other issues that prevent QEMU from working at 
all (for me, at any rate, and not just with debugging), but those fixes 
are not yet ready.

Actually POWERPC_EXCP_DEBUG can not happen in user mode, while
EXCP_DEBUG should be handled. The mistake come from a renaming of
all PowerPC EXCP_* defines into POWERPC_EXCP_*.

I have applied a patch to fix that.
