x86/opus_dsp: rename to celt_pvq
Its only used in the encoder and in CELT's PVQ. |

opus_pvq_search: Restore the proper use of conditional define and simplify the function name suffix handling.
Using named define properly documents the code paths. It also avoids passing additional numbered arguments through multiple levels of macro templates. The suffix handling is done by concatenation, like in other asm functions and avoid having two separate "cglobal" defines. Signed-off-by: Ivan Kalvachev <ikalvachev@gmail.com> |

opus_pvq_search: split functions into exactness and only use the exact if its faster
This splits the asm function into exact and non-exact version. The exact version is as fast or faster on newer CPUs (which EXTERNAL_AVX_FAST describes well) whilst the non-exact version is faster than the exact on older CPUs. Also fixes yasm compilation which doesn't accept !cpuflags(avx) syntax. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com> |

ops_pvq_search: remove dead macro
There's no point in toggling it, even for debugging. Its just worse. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com> |
