* x86/float_dsp: add SSE2 and AVX versions of scalarproduct_doubleJames Almer2024-06-031-0/+52

* x86: replace explicit REP_RETs with RETsLynne2023-02-011-9/+9
| | | | | | | | | | | | | | | | | | | 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.

* avutil/x86/float_dsp: Remove obsolete 3dnowext functionAndreas Rheinhardt2022-06-221-24/+1
| | | | | | | | | | | x64 always has MMX, MMXEXT, SSE and SSE2 and this means that some functions for MMX, MMXEXT, SSE and 3dnow are always overridden by other functions (unless one e.g. explicitly disables SSE2). So given that the only systems which benefit from ff_vector_fmul_window_3dnowext are truely ancient 32bit AMD x86s it is removed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
