      Fix Thumb-1 BE32 execution and disassembly. · f7478a92
      Julian Brown authored 
      
Thumb-1 code has some issues in BE32 mode (as currently implemented). In
short, since bytes are swapped within words at load time for BE32
executables, this also swaps pairs of adjacent Thumb-1 instructions.

This patch un-swaps those pairs of instructions again, both for execution,
and for disassembly. (The previous version of the patch always read four
bytes in arm_read_memory_func and then extracted the proper two bytes,
in a probably misguided attempt to match the behaviour of actual hardware
as described by e.g. the ARM9TDMI TRM, section 3.3 "Endian effects for
instruction fetches". It's less complicated to just read the correct
two bytes though.)

      Remove remainders of HPPA backend · d41f3c3c
      Thomas Huth authored 
      
The HPPA backend has been removed by the following commit:

    802b5081
    tcg-hppa: Remove tcg backend

But some small pieces of the HPPA backend still survived until
today. Since we also do not have support for a HPPA target in
QEMU, we can nowadays safely remove the remaining HPPA parts
(like the disassembler code, or the detection of HPPA in the
configure script).

      all: Clean up includes · d38ea87a

Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

This commit was created with scripts/clean-includes.

      disas: Remove uses of CPU env · d49190c4
      Peter Crosthwaite authored 
      
disas does not need to access the CPU env for any reason. Change the
APIs to accept CPU pointers instead. Small change pattern needs to be
applied to all target translate.c. This brings us closer to making
disas.o a common-obj and less architecture specific in general.

      disas: Implement disassembly output for A64 · 999b53ec
      Claudio Fontana authored 
      
Use libvixl to implement disassembly output in debug
logs for A64, for use with both AArch64 hosts and targets.

[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]

      disas: Fix printing of addresses in disassembly · 636bd289
      Peter Maydell authored 
      
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.)

      fix some common typos · a31f0531

      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
  sed -i '54s!miniscule!minuscule!' disas.c

Also, manually fix "arithmentic", spotted by Peter Maydell:

      Userspace ARM BE8 support · d8fd2954
      Paul Brook authored 
      
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
