2014-02-08disas: Implement disassembly output for A64Claudio Fontana
Use libvixl to implement disassembly output in debug logs for A64, for use with both AArch64 hosts and targets. Signed-off-by: Claudio Fontana <claudio.fontana@linaro.org> [PMM: * added support for target disassembly * switched to custom QEMUDisassembler so the output format matches what QEMU expects * make sure we correctly fall back to "just print hex" if we didn't build the AArch64 disassembler because of lack of a C++ compiler * rename from 'aarch64' to 'arm-a64' because this is a disassembler for the A64 instruction set * merge aarch64.c and aarch64-cxx.cc into one C++ file * simplify the aarch64.c<->aarch64-cxx.cc interface] Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2012-09-21tcg-sparc: Assume v9 cpu always, i.e. force v8plus in 32-bit mode.Richard Henderson
Current code doesn't actually work in 32-bit mode at all. Since no one really noticed, drop the complication of v7 and v8 cpus. Eliminate the --sparc_cpu configure option and standardize macro testing on TCG_TARGET_REG_BITS / HOST_LONG_BITS Signed-off-by: Richard Henderson <rth@twiddle.net>
2012-07-14disas: Fix printing of addresses in disassemblyPeter Maydell
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.)

2012-04-06Userspace ARM BE8 supportPaul Brook
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. Signed-off-by: Paul Brook <paul@codesourcery.com> [PMM: various changes, mostly as per my suggestions in code review: * rebase * use EF_ defines rather than hardcoded constants * make bswap_code a bool for future VMSTATE macro compatibility * update comment in cpu.h about TB flags bit field usage * factor out load-code-and-swap into arm_ld*_code functions and get_user_code* macros * fix stray trailing space at end of line * added braces in disas.c to satisfy checkpatch ] Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>

Sparc disassembler wants to check previous addresses for some stuff and this may actually cause faults to be generated to the guest if the address is close to page start, because of the function used for the memory access.

2009-03-05monitor: Rework API (Jan Kiszka)aliguori
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.
