Now that we fuzz against Unicorn, we aren't just restricted to VFPv2.
VFPv3 and VFPv4 facilities can now be implemented. This renames
constructs mentioning VFPv2 to just refer to VFP.
Implements the ARM-mode variants of the CRC32 instructions introduced
within ARMv8. This is also one of the instruction cases where there is
UNPREDICTABLE behavior that is constrained (we must do one of the
options indicated by the reference manual).
In both documented cases of constrained unpredictable behavior, we treat
the instructions as unpredictable in order to allow library users to
hook the unpredictable exception to provide the intended behavior they
desire.
We also make the arrays static here, as MSVC tends to load the whole
array every time the function is called, instead of storing the data
within rodata.
This also line breaks the elements a little earlier for readability.
Replaces type aliases of raw integral types with the more type-safe Imm
template, like how the AArch64 frontend has been using it.
This makes the two frontends more consistent with one another.
The SetRegister() IR function doesn't allow specifying the PC as a
register. This is a discrepancy that slipped through (my bad). Instead,
we can use BranchWritePC(), like how the other similar PC modifying
locations do it.
Provides basic implementations of the barrier instruction introduced
within ARMv7. Currently these simply mirror the behavior of the AArch64
equivalents.
Performs a similar tidying up of the Thumb translator, like what was
done with the regular ARM translator to make it consistent with the rest
of the codebase.
The A32 backend (both Thumb and ARM), will likely see more changes to it
in the near future, so this just acts as a "dusting off".
Generally hash functions shouldn't throw exceptions. It's also a
requirement for the standard library-provided hash functions to not
throw exceptions.
An exception to this rule is made for user-defined specializations,
however we can just be consistent with the standard library on this to
allow it to play nicer with it.
While we're at it, we can also make the std::less specializations
noexcpet as well, since they also can't throw.
