2014-06-16monitor: QEMU Monitor Instruction Disassembly Incorrect for PowerPC LE ModeTom Musta1-2/+12
The monitor support for disassembling instructions does not honor the MSR[LE] bit for PowerPC processors. This change enhances the monitor_disas() routine by supporting a flag bit for Little Endian mode. Bit 16 is used since that bit was used in the analagous guest disassembly routine target_disas(). Also, to be consistent with target_disas(), the disassembler bfd_mach field can be passed in the flags argument.

2012-07-14disas: Fix printing of addresses in disassemblyPeter Maydell1-0/+19
In our disassembly code, the bfd_vma type is always 64 bits, even if the target's virtual address width is only 32 bits. This means that when we print out addresses we need to truncate them to 32 bits, to avoid odd output which has incorrectly sign-extended a value to 64 bits, for instance this ARM example: 0x80479a60: e59f4088 ldr r4, [pc, #136] ; 0xffffffff80479a4f (It would also be possible to truncate before passing the address to info->print_address_func(), but truncating in the final print function is the same approach that binutils takes to this problem.)

Add support for ARM BE8 userspace binaries. i.e. big-endian data and little-endian code. In principle LE8 mode is also possible, but AFAIK has never actually been implemented/used. System emulation doesn't have any useable big-endian board models, but should in principle work once you fix that. Dynamic endianness switching requires messing with data accesses, preferably with TCG cooperation, and is orthogonal to BE8 support.

2009-03-05monitor: Rework API (Jan Kiszka)aliguori1-9/+8
Refactor the monitor API and prepare it for decoupled terminals: term_print functions are renamed to monitor_* and all monitor services gain a new parameter (mon) that will once refer to the monitor instance the output is supposed to appear on. However, the argument remains unused for now. All monitor command callbacks are also extended by a mon parameter so that command handlers are able to pass an appropriate reference to monitor output services. For the case that monitor outputs so far happen without clearly identifiable context, the global variable cur_mon is introduced that shall once provide a pointer either to the current active monitor (while processing commands) or to the default one. On the mid or long term, those use case will be obsoleted so that this variable can be removed again. Due to the broad usage of the monitor interface, this patch mostly deals with converting users of the monitor API. A few of them are already extended to pass 'mon' from the command handler further down to internal functions that invoke monitor_printf. At this chance, monitor-related prototypes are moved from console.h to a new monitor.h. The same is done for the readline API.
