-Subject: [PATCH] [cmake] disable NEON runtime check on clang-cl
-
-When enabling runtime NEON checking for clang-cl, the linker would error out with `undefined symbol: __emit`, since clang doesn't actually implement this instruction. Therefore it makes sense to disable the runtime check by default on this platform, until either this is fixed or a clang-cl compatible intrinsic check is added (I don't have enough knowledge of MSVC to do this)

PavelBARABANOV	5d150cac5c	[dynarmic, am, android, ns] Fixes the latest qlaunch regressions on Android and adds cmd23 for launching games on FW 23 (#4407 ) - [x] I have read and followed the [Contribution Guidelines](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/CONTRIBUTING.md#code-contributions). - [x] I have read and followed the [AI Policy](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/docs/policies/AI.md) - [x] I have read and followed the [Coding Guidelines](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/docs/policies/Coding.md) to the best of my ability. ------------------- [dynarmic] use TST + B.NE instead of TBNZ for marked bit Fixes qlaunch and ac3 crashes. [am] Bruno FIX OVERLAY 2.0 Fixes incorrect load display when the overlay applet is enabled in AC3. [android] handle empty programId in Game.settingsName The ReShade post-processing change started calling SettingsFile.loadCustomConfig() on every drawer open through withPerGameConfig(), which exposed a pre-existing crash in Game.settingsName when programId was an empty string. [ns] use GetApplicationControlData3 for cmd23 in IReadOnlyApplicationControlDataInterface We can use this method for now for launching games on fw23, while we don't have all the information.

lizzie	ff8368c606	[audio] Replace libopus with FFmpeg (#4169 ) FFmpeg offers two opus decoders: - libopus, this one is fed the same data (that affects output) as the previous libopus decoder had as well - native opus decoder: this only takes Float32 samples, we then need to invoke swrescale to translate between s16 (what switch sends) and float32 (what FFmpeg expects), the process is computationally more expensive, but trades off neatly as the native opus decoder is very optimised It also relegates the handling to FFmpeg, which simplifies existing code (more concretely, by using the "fill/drain" scheme for packets/frames) Closes #2897 Signed-off-by: lizzie <lizzie@eden-emu.dev> Co-authored-by: crueter <crueter@eden-emu.dev> Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/4169 Reviewed-by: CamilleLaVey <camillelavey99@gmail.com> Reviewed-by: Maufeat <sahyno1996@gmail.com>	2026-09-12 09:59:33 +02:00
