Martin Storsjö	cb803a0072	swscale: aarch64: Fix yuv2rgb with negative strides Treat the 32 bit stride registers as signed. Alternatively, we could make the stride arguments ptrdiff_t instead of int, and changing all of the assembly to operate on these registers with their full 64 bit width, but that's a much larger and more intrusive change (and risks missing some operation, which would clamp the intermediates to 32 bit still).

Lynne	3e098cca6e	aarch64/yuv2rgb_neon: fix return value We return 0 for this particular architecture but should instead be returning the number of lines. Fixes users who check the return value matches what they expect.	4 years ago
Clément Bœsch	cab9661dba	sws/aarch64/yuv2rgb: honor iOS calling convention y_offset and y_coeff being successive 32-bit integers, they are packed into 8 bytes instead of 2x8 bytes. See https://developer.apple.com/library/ios/documentation/Xcode/Conceptual/iPhoneOSABIReference/Articles/ARM64FunctionCallingConventions.html > iOS diverges from Procedure Call Standard for the ARM 64-bit > Architecture in several ways [...] > In the generic procedure call standard, all function arguments passed > on the stack consume slots in multiples of 8 bytes. In iOS, this > requirement is dropped, and values consume only the space required. [...] > Padding is still inserted on the stack to satisfy arguments’ alignment > requirements.	9 years ago
