Currently the ARM SVE helper code defines locally some utility
functions for swapping 16-bit halfwords within 32-bit or 64-bit
values and for swapping 32-bit words within 64-bit values,
parallel to the byte-swapping bswap16/32/64 functions.
We want these also for the ARM MVE code, and they're potentially
generally useful for other targets, so move them to bitops.h.
(We don't put them in bswap.h with the bswap* functions because
they are implemented in terms of the rotate operations also
defined in bitops.h, and including bitops.h from bswap.h seems
better avoided.)

Implement the MVE LETP insn. This is like the existing LE loop-end
insn, but it must perform an FPU-enabled check, and on loop-exit it
resets LTPSIZE to 4.
To accommodate the requirement to do something on loop-exit, we drop
the use of condlabel and instead manage both the TB exits manually,
in the same way we already do in trans_WLS().
The other MVE-specific change to the LE insn is that we must raise an
INVSTATE UsageFault insn if LTPSIZE is not 4.

In commit a3494d4671 we reworked the M-profile handling of its
checks for when the NOCP exception should be raised because the FPU
is disabled, so that (in line with the architecture) the NOCP check
is done early over a large range of the encoding space, and takes
precedence over UNDEF exceptions. As part of this, we removed the
code from full_vfp_access_check() which raised an exception there for
M-profile with the FPU disabled, because it was no longer reachable.
For MVE, some instructions which are outside the "coprocessor space"
region of the encoding space must nonetheless do "is the FPU enabled"
checks and possibly raise a NOCP exception. (In particular this
covers the MVE-specific low-overhead branch insns LCTP, DLSTP and
WLSTP.) To support these insns, reinstate the code in
full_vfp_access_check(), so that their trans functions can call
vfp_access_check() and get the correct behaviour.

On A-profile, PSR bits [15:10][26:25] are always the IT state bits.
On M-profile, some of the reserved encodings of the IT state are used
to instead indicate partial progress through instructions that were
interrupted partway through by an exception and can be resumed.
These resumable instructions fall into two categories:
(1) load/store multiple instructions, where these bits are called
"ICI" and specify the register in the ldm/stm list where execution
should resume. (Specifically: LDM, STM, VLDM, VSTM, VLLDM, VLSTM,
CLRM, VSCCLRM.)
(2) MVE instructions subject to beatwise execution, where these bits
are called "ECI" and specify which beats in this and possibly also
the following MVE insn have been executed.
There are also a few insns (LE, LETP, and BKPT) which do not use the
ICI/ECI bits but must leave them alone.
Otherwise, we should raise an INVSTATE UsageFault for any attempt to
execute an insn with non-zero ICI/ECI bits.
So far we have been able to ignore ECI/ICI, because the architecture
allows the IMPDEF choice of "always restart load/store multiple from
the beginning regardless of ICI state", so the only thing we have
been missing is that we don't raise the INVSTATE fault for bad guest
code. However, MVE requires that we honour ECI bits and do not
rexecute beats of an insn that have already been executed.
Add the support in the decoder for handling ECI/ICI:
* identify the ECI/ICI case in the CONDEXEC TB flags
* when a load/store multiple insn succeeds, it updates the ECI/ICI
state (both in DisasContext and in the CPU state), and sets a flag
to say that the ECI/ICI state was handled
* if we find that the insn we just decoded did not handle the
ECI/ICI state, we delete all the code that we just generated for
it and instead emit the code to raise the INVFAULT. This allows
us to avoid having to update every non-MVE non-LDM/STM insn to
make it check for "is ECI/ICI set?".
We continue with our existing IMPDEF choice of not caring about the
ICI state for the load/store multiples and simply restarting them
from the beginning. Because we don't allow interrupts in the middle
of an insn, the only way we would see this state is if the guest set
ICI manually on return from an exception handler, so it's a corner
case which doesn't merit optimisation.
ICI update for LDM/STM is simple -- it always zeroes the state. ECI
update for MVE beatwise insns will be a little more complex, since
the ECI state may include information for the following insn.

It turns out some software does this: EDK2, in
GicV3ExitBootServicesEvent(), unconditionally write EOIR for all
interrupts that it manages. This now causes QEMU to abort when running
UEFI on a VM with GICv3. Although it is UNPREDICTABLE behavior and EDK2
does need fixing, the punishment seems a little harsh, especially since
icc_eoir_write() already tolerates writes of nonexistent interrupt
numbers. Display a guest error and tolerate spurious EOIR writes.

The highest VBE_DISPI_INDEX_ID version supported by QEMU is
VBE_DISPI_ID5. But currently QEMU only allows writing values up to
VBE_DISPI_ID4 to the VBE_DISPI_INDEX_ID register.
As a result of this when a lower version is written to this register and
later VBE_DISPI_ID5 is written back, reads from the register will
continue to report the lower version.
Indeed SeaBIOS is doing that during VGA initialization which causes
guests to always read VBE_DISPI_ID0 instead of the correct version.

The GDateTime APIs provided by GLib avoid portability pitfalls, such

often results in simpler code too.
