e1cb6369b0 Add AVX vector path to float2half/half2float 
Makes e. g. matrix multiplication 2x faster:
name         old cpu/op  new cpu/op  delta
BM_convers   181ms ± 1%    62ms ± 9%  -65.82%  (p=0.016 n=4+5)

Tested on all possible input values (not adding tests, since they
take a long time).

3c724c44cf Fix strict aliasing bug causing product_small failure. 
Packet loading is skipped due to aliasing violation, leading to nullopt matrix
multiplication.

Fixes #2327.

7792b1e909 Fix AVX2 PacketMath.h. 
There were a couple typos ps -> epi32, and an unaligned load issue.

def145547f Add missing packet types in pset1 call. 
Oops, introduced this when "fixing" integer packets.

3d4ba855e0 Fix AVX integer packet issues. 
Most are instances of AVX2 functions not protected by
`EIGEN_VECTORIZE_AVX2`.  There was also a missing semi-colon
for AVX512.

52a5f98212 Get rid of code duplication for conj_helper. For packets where LhsType=RhsType a single generic implementation suffices. For scalars, the generic implementation of pconj automatically forwards to numext::conj, so much of the existing specialization can be avoided. For mixed types we still need specializations. 2021-06-24 15:47:48 -07:00
