Rémi Denis-Courmont 3a134e8299 lavu/fixed_dsp: optimise R-V V fmul_reverse ... Gathers are (unsurprisingly) a notable exception to the rule that R-V V gets faster with larger group multipliers. So roll the function to speed it up. Before: vector_fmul_reverse_fixed_c: 2840.7 vector_fmul_reverse_fixed_rvv_i32: 2430.2 After: vector_fmul_reverse_fixed_c: 2841.0 vector_fmul_reverse_fixed_rvv_i32: 962.2 It might be possible to further optimise the function by moving the reverse-subtract out of the loop and adding ad-hoc tail handling.		2023-11-23 18:57:18 +02:00
