two main issues:
shader_environment.cpp
Support Mesa nv50_ir-compiled homebrew fragment shaders
Mesa nv50_ir (used by NZP-Switch via libdrm_nouveau) emits Maxwell SASS that differs from NVN in two ways our shader pipeline didn't account for, causing "infinite" loops during shader scanning.
How? TryFindSize() previously detected end-of-shader only via NVN's "BRA $-1" self-branch trailer (SELF_BRANCH_A/B). Mesa-compiled shaders end with an unconditional @PT EXIT and emit no trailer, so scanning ran past the shader and looped to MAXIMUM_SIZE.
Fix: Added a secondary match against @PT EXIT T (opcode 0xE30, predicate PT, flow T) as a fallback terminator. The mask is estrictive enough to reject predicated EXITs, conditional-flow EXITs, and sched control words, so well-formed NVN shaders see no ehavior change (their single @PT EXIT immediately precedes BRA $-1, and both detections return the same size).
load_store_attribute.cpp + attribute.h
IPA's is_perspective check only applied the ×position_w correction for IR::IsGeneric() attributes, and used a per-component SPH lookup. Two failure modes followed:
1. Mesa fragment shaders read varyings via legacy attribute slots
(ColorFrontDiffuse, FixedFncTexture, FogCoordinate) which are
remapped to generic varyings later by ConvertLegacyToGeneric. At
IPA-translation time they're still legacy, so IsGeneric() was
false and the inject was skipped — but the resulting GLSL/SPIR-V
varying was Smooth (perspective-correct), and the SASS still
issued its manual perspective dance via MUFU.RCP(ATTR_W)+FMUL,
compounding an extra ×clip_w factor. NZP fog (eye_z distance
varying) ended up as eye_z⁴×density² instead of eye_z²×density²,
saturating fog to white everywhere.
2. Even for legacy attrs that should inject, Mesa stores them in two formats selected by the IPA's interpolation_mode field:
Pass/Multiply/Constant → attr/w (perspective); inject ×position_w
Sc (ScreenLinear) → raw attr; do NOT inject
Unconditionally injecting for Sc dims vertex colors by 1/clip_w because there's no SASS multiplier to round-trip it back.
Fix: extend the IPA correction path to also fire on IsLegacyAttribute(), gated on interpolation_mode != Sc. While here, the generic-path check is widened from per-component to vector-level (first non-Unused PixelImap, with all-Unused fallthrough treated as Perspective) so it matches the GLSL interpolation qualifier picked by CollectInterpolationInfo — this fixes the same all-zeroed-imap case Mesa exposes for explicit generics. IsLegacyAttribute moved from translate_program.cpp's anonymous namespace into attribute.h next to IsGeneric so IPA can reach it.
Tested on NaziZombies:Portable (Switch homebrew): fog now matches real
hardware, vertex-colored geometry (hand, gun, decals) renders correctly.

Function polymorphism where it wasn't needed? especially on tight code loops like translating code and whatnot?
You may think the compiler was fine with this but nah, it just made codegen for all those paths; I didn't check LTO but I'd assume it behaves the same (since the "black box" from most walkers suck) - basically bunch of code that isn't longer used
Also uniformly declaring all functions (i.e same args, return value) makes the entire switch statment way nicer

The compiler is very smart, I trust the compiler to make a proper decoder selector rather than rolling our own.
Probably mostly benefitted on PGO builds.
Directly affects cache recompilation times (test with pipeline shaders OFF to force shaders to rebuild :)
Also restores CCTLT so we have the full ISA (or do we? Is ISBEWR missing? - someone should run fuzzing :)

Adds the initial support for Internal Stage Buffer Entry Read - ISBERD, a mechanism used to read internal stage buffer entries with accurate per-stage synchronization. This enables more precise tracking of GPU buffer accesses, improving compatibility with games relying on fine-grained intermediate rendering stages (especially UE4 titles and post-processing heavy engines).

revert [android] Snapdragon 865 patches (#23)

Reverted due to heavy performance hits on Android with higher specifications, will be adjusted to be included in a specific build for older A6XX devices, as 855, 860, 865, 870, meanwhile it does fix critical issues with certain games crashing due to memory and VRAM usage, hits performance on SoC that can do it without this special flags.
revert [Texture_cache] Better memory handling for devices with lower memory allocations (#233)
Means games like Minecraft Dungeons, Sea of Stars, Luigi Mansion 2, Astroneer, Alan Wake, etc are now playable.
It also cleans up the recent abi.cpp and bindless texture commits a bit.
Everything is in #ifdef ANDROID - The biggest change is CACHING_PAGEBITS = 12.
Without that the way the buffercache grows and joins buffers can cause Android to run out of memory (as you end up with just one big buffer that needs to be copied every time it grows)
Also patches up ffmpeg issues.

[REUSE] is a specification that aims at making file copyright
information consistent, so that it can be both human and machine
readable. It basically requires that all files have a header containing
copyright and licensing information. When this isn't possible, like
when dealing with binary assets, generated files or embedded third-party
dependencies, it is permitted to insert copyright information in the
`.reuse/dep5` file.
Oh, and it also requires that all the licenses used in the project are
present in the `LICENSES` folder, that's why the diff is so huge.
This can be done automatically with `reuse download --all`.
The `reuse` tool also contains a handy subcommand that analyzes the
project and tells whether or not the project is (still) compliant,
`reuse lint`.
Following REUSE has a few advantages over the current approach:
- Copyright information is easy to access for users / downstream
- Files like `dist/license.md` do not need to exist anymore, as
`.reuse/dep5` is used instead
- `reuse lint` makes it easy to ensure that copyright information of
files like binary assets / images is always accurate and up to date
To add copyright information of files that didn't have it I looked up
who committed what and when, for each file. As yuzu contributors do not
have to sign a CLA or similar I couldn't assume that copyright ownership
was of the "yuzu Emulator Project", so I used the name and/or email of
the commit author instead.
[REUSE]: https://reuse.software

This formats all copyright comments according to SPDX formatting guidelines.
Additionally, this resolves the remaining GPLv2 only licensed files by relicensing them to GPLv2.0-or-later.
Thanks to @asLody for optimizing this function. This raised the focus that this function should be optimized more.
The current table assumes that the host GPU is able to invert for free, so only AND,OR,XOR are accumulated in the performance metrik.

Support ignoring immediate out of bound writes. Writing dynamically out
of bounds is not yet supported (e.g. R0+0x4).
Reading out of bounds yields zero. This is supported checking for the
size from the IR; if the input is immediate, the optimization passes
will drop it.
