- Most notably, each version of the manually vectorized code now resides in their own files.
- Depending on the rendering situation, the new AVX2 code may increase rendering performance by 5% to up to 50%.
- Certain functions automatically gain manual vectorization support since the new GPU code makes use of the new general-purpose copy functions that were added in commit e991b16. In other words, AVX-512 and AltiVec builds also benefit from this.
- Also renames "Altivec" to "AltiVec" to remain consistent with Colorspace Handler's naming.
- Also adds an AltiVec accelerated version of the clear image parser.
- Final Release builds still remain as PowerPC 32-bit, Intel 32-bit, and Intel 64-bit. ARM64 is not supported yet.
- PowerPC 32-bit and Intel 32-bit continue to require macOS v10.5 Leopard like before, but the Intel 64-bit binary now requires macOS v10.7 Lion or later. (Now, the Intel 64-bit binary will simply fail to run on Leopard and Snow Leopard.)
- Specifically, we're now respecting uniform control flow for texture lookups, for which older/stricter drivers will silently fail because they consider texture lookups within conditional blocks to be undefined.
- This change partially reverts commit 87cb2f6, but still preserves the elimination of the destructor, which is probably the code simplification that was originally wanted, I guess.
- Apparently, KVO-based UI updates being made across threads are a big no-no in the macOS v10.14 SDK and later. So now we need to make sure that ALL KVO-based UI updates are done on the main thread only.
- Fixes a crash that can occur on startup or when modifying the Video Pixel Scaler in Preferences. Fixes#321. (Regression from commit 0663661.)
- Fixes a crash on startup where write+execute privileges returned by mprotect() are not supported when compiled against the macOS v10.15 SDK or later. Fixes#335.
- Fixes a possible crash that can occur if an invalid ID is sent when trying to set the 3D Rendering Engine. Maybe fixes#342.
- The script that renames the DeSmuME.app package with the git version now runs as a Build Post-Action script rather than as the last build rule. This is to fix an incompatibility with code signing, which is now forced in Xcode 11 and later.
- Update some variables to comply with newer and stricter compiler rules.
