hf_apply_noise_0_c: 35.7 hf_apply_noise_0_rvv_f32: 9.5 hf_apply_noise_1_c: 38.5 hf_apply_noise_1_rvv_f32: 10.0 hf_apply_noise_2_c: 35.5 hf_apply_noise_2_rvv_f32: 9.7 hf_apply_noise_3_c: 38.5 hf_apply_noise_3_rvv_f32: 10.0 Maybe extending the noise table manually is not such great idea, but I not quite sure how to deal with that otherwise? Allocating the table dynamically is possible but would require an ELF destructor to clean up.
