Niklas Haas	67adb30322	swscale: rename SwsContext to SwsInternal And preserve the public SwsContext as separate name. The motivation here is that I want to turn SwsContext into a public struct, while keeping the internal implementation hidden. Additionally, I also want to be able to use multiple internal implementations, e.g. for GPU devices. This commit does not include any functional changes. For the most part, it is a simple rename. The only complications arise from the public facing API functions, which preserve their current type (and hence require an additional unwrapping step internally), and the checkasm test framework, which directly accesses SwsInternal. For consistency, the affected functions that need to maintain a distionction have generally been changed to refer to the SwsContext as sws, and the SwsInternal as c. In an upcoming commit, I will provide a backing definition for the public SwsContext, and update `sws_internal()` to dereference the internal struct instead of merely casting it.

Lynne	bbe95f7353	x86: replace explicit REP_RETs with RETs From x86inc: > On AMD cpus <=K10, an ordinary ret is slow if it immediately follows either > a branch or a branch target. So switch to a 2-byte form of ret in that case. > We can automatically detect "follows a branch", but not a branch target. > (SSSE3 is a sufficient condition to know that your cpu doesn't have this problem.) x86inc can automatically determine whether to use REP_RET rather than REP in most of these cases, so impact is minimal. Additionally, a few REP_RETs were used unnecessary, despite the return being nowhere near a branch. The only CPUs affected were AMD K10s, made between 2007 and 2011, 16 years ago and 12 years ago, respectively. In the future, everyone involved with x86inc should consider dropping REP_RETs altogether.	2 years ago

Alan Kelly	f900a19fa9	libswscale: Adds ff_hscale8to15_4_avx2 and ff_hscale8to15_X4_avx2 for all filter sizes. Fixes so that fate under 64 bit Windows passes. These functions replace all ff_hscale8to15_*_ssse3 when avx2 is available. Signed-off-by: James Almer <jamrial@gmail.com>	3 years ago
