The HPPA backend has been removed by the following commit:
802b508123
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).

Move the target_disas() alpha specifics to the CPUClass::disas_set_info()
hook and delete the #ifdef specific code in disas.c.
This also makes monitor_disas() consistent with target_disas(), as
monitor_disas() was missing a set of the BFD (This was an omission from

Move the target_disas() ARM specifics to the QOM disas_set_info hook
and delete the ARM specific code in disas.c.
This has the extra advantage of the more fully featured target_disas()
implementation now applying to monitor_disas().
Currently, target_disas() has multi-endian, thumb and AArch64
support whereas the existing monitor_disas() support only has vanilla
AA32 support.
E.G. Running an AA64 linux kernel the following -d in_asm disas happens
(taget_disas()):
IN:
0x0000000040000000: 580000c0 ldr x0, pc+24 (addr 0x40000018)

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.

Signed-off-by: Richard Henderson <rth@twiddle.net>
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.)

In principle LE8 mode is also possible, but AFAIK has never actually

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.
