Everything that links in core doesn't need to see anything related to bochs, because it's only used internally.
Anything else that relies on bochs should be linking it in explicitly.
The general convention is to return a reference to the object that was
acted on, otherwise you can get into situations with errors because the
type wasn't being propagated properly
Using this in its current form would invoke undefined behavior, as it's
using a union to type pun between data types. It's also, well, unused,
so we don't need to keep it around.
We already read the necessary information with the
HostRead_Instruction() call. Internally, it calls HostRead_U32() as
well, so there's no difference in behavior.
If the locked cache isn't enabled, dcbz_l is illegal to execute
(locked cache is off, locked cache instructions don't work, makes sense)
This makes exception handling more accurate. It was previously possible to hit the DSI exception
handler when HID2[LCE] is set to zero, which isn't correct.
With this change we no longer hit the DSI handler, however we still have a lingering issue elsewhere
likely to do with exception precedence, we seem to hit the Floating Point exception handler instead
in some cases. This isn't due to the instruction itself directly however, so this is just another bug
to fix elsewhere.
We already use a custom CMakeLists file for xxhash, so we can just make it's headers
public as part of its target interface.
This way, only libraries that link in the xxhash target will see its headers, as opposed
to every target under the top-level directory.
CMake already has this functionality built-in. This lessens depending on the host system environment
and is more cross-platform friendly (which is always nice from a build-system point of view).
In the case we had X11 libs available, we'd allocate an XRRConfiguration instance and pass it
to the GraphicsWindow instance, but it would never actually be freed.
add_definitions and include_directories don't operate on a by-target basis, they act on a
by-directory basis (i.e. if we defined two targets, A and B, in this CMakeLists file, add_definitions
would add the definitions to the COMPILE_DEFINITIONS directory property which both A and B would
implicitly use).
The same idea applies to include_directories, only it appends to the INCLUDE_DIRECTORIES directory
property.
Instead, specify these on the target to keep scope as narrow as possible.
This is one of the conditions for an alignment exception documented in
the 750CL architecture reference manual in section 4.5.6, which also
applies to the Gekko microprocessor.
This is an exception condition documented within section 4.5.6 in the

Also moves dcbz_l's implementation out of Interpreter_Paired and beside
dcbz where it belongs.
