* Fixed division edge case: Div64/32 and Div64/64 set the remainder to 0 if dividend == INT64_MIN && divisor == -1
* Fixed CPU edge case where ARM9 ALU ops would switch to Thumb even when they shouldn't
* Only clear the lowest bit of the jump address in ALU ops with rd==15 (on recommendation of RSDuck)
* Draft GPU3D renderer modularization
* Update sources C++ standard to C++17
The top-level `CMakeLists.txt` is already using the C++17 standard.
* Move GLCompositor into class type
Some other misc fixes to push towards better modularity
* Make renderer-implementation types move-only
These types are going to be holding onto handles
of GPU-side resources and shouldn't ever be copied around.
* Fix OSX: Remove 'register' storage class specifier
`register` has been removed in C++17...
But this keyword hasn't done anything in years anyways.
OSX builds consider this "warning" an error and it
stops the whole build.
* Add RestartFrame to Renderer3D interface
* Move Accelerated property to Renderer3D interface
There are points in the code base where we do:
`renderer != 0` to know if we are feeding
an openGL renderer. Rather than that we can instead just have this be
a property of the renderer itself.
With this pattern a renderer can just say how it wants its data to come
in rather than have everyone know that they're talking to an OpenGL
renderer.
* Remove Accelerated flag from GPU
* Move 2D_Soft interface in separate header
Also make the current 2D engine an "owned" unique_ptr.
* Update alignment attribute to standard alignas
Uses standardized `alignas` rather than compiler-specific
attributes.
https://en.cppreference.com/w/cpp/language/alignas
* Fix Clang: alignas specifier
Alignment must be specified before the array to align the entire array.
https://en.cppreference.com/w/cpp/language/alignas
* Converted Renderer3D Accelerated to variable
This flag is checked a lot during scanline rasterization. So rather
than having an expensive vtable-lookup call during mainline rendering
code, it is now a public constant bool type that is written to only once
during Renderer3D initialization.
* Fix directory path when extracting from archive
* Don't create new dir in execution dir of melonds
* Create it beside the archive instead

- savestates used to read a four bytes from a single byte value
- a few unassigned variables
- some other things
- also make the ROR macro an inline function
- more reliable code invalidation detection
- blocks aren't stopped at any branch, but are being followed
if possible to get larger blocks
- idle loop recognition
- optimised literal loads, load/store cycle counting
and loads/stores from constant addresses

Previously, the GBA memory was 0xFF-filled
on both CPUs. However, GBATEK reports that
the deselected CPU is 0x00-filled, and that
some titles depend on this behavior to
function properly.
* immediately clear AES busy flag when the block count is zero (occurs when loading DSi cart games)
* implement NDMA start modes that have an old-DMA equivalent (except for GXFIFO mode)
now it boots DSi carts!
