Richard Henderson 9b9c37c364 tcg-sparc: Assume v9 cpu always, i.e. force v8plus in 32-bit mode.
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

Peter Maydell 636bd28939 disas: Fix printing of addresses in disassembly
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.)

Jim Meyering a31f053129 fix some common typos
These were identified using: http://github.com/lyda/misspell-check
and run like this to create a bourne shell script using GNU sed's
-i option:

git ls-files|grep -vF .bin | misspellings -f - |grep -v '^ERROR:' |perl \
-pe 's/^(.*?)\[(\d+)\]: (\w+) -> "(.*?)"$/sed -i '\''${2}s!$3!$4!'\'' $1/'

Manually eliding the FP, "rela->real" and resolving "addres" to
address (not "adders") we get this:

  sed -i '450s!thru!through!' Changelog
  sed -i '260s!neccessary!necessary!' coroutine-sigaltstack.c

Paul Brook d8fd295499 Userspace ARM BE8 support
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.

[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

Using cpu_physical_memory_read, cpu_physical_memory_write and ldub_phys
improves readability and allows removing some type casts.

lduw_phys and ldl_phys were not used because both require aligned
addresses. Therefore it is not possible to simply replace existing
calls by one of these functions.

Blue Swirl e612a1f725 Fix disassembler memory accesses
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.

Fix by changing ldub_code to cpu_memory_rw_debug, which doesn't trigger

aliguori 376253ece4 monitor: Rework API (Jan Kiszka)
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.
