9005f0111f Replace compiler's alignas/alignof extension by respective c++11 keywords when available. This also fix a compilation issue with gcc-4.7. 2019-01-11 17:10:54 +01:00

e6b217b8dd bug #1652: implements a much more accurate version of vectorized sin/cos. This new version achieve same speed for SSE/AVX, and is slightly faster with FMA. Guarantees are as follows: 
- no FMA: 1ULP up to 3pi, 2ULP up to sin(25966) and cos(18838), fallback to std::sin/cos for larger inputs
  - FMA: 1ULP up to sin(117435.992) and cos(71476.0625), fallback to std::sin/cos for larger inputs

0f6f75bd8a Implement a faster fix for sin/cos of large entries that also correctly handle INF input. 2018-12-23 17:26:21 +01:00

38d704def8 Make sure that psin/pcos return number in [-1,1] for large inputs (though sin/cos on large entries is quite useless because it's inaccurate) 2018-12-23 16:13:24 +01:00

efa4c9c40f bug #1615: slightly increase the default unrolling limit to compensate for changeset 101ea26f5e 
.
This solves a performance regression with clang and 3x3 matrix products.

b477d60bc6 Extend the generic psin_float code to handle cosine and make SSE and AVX use it (-> this adds pcos for AVX) 2018-11-30 11:26:30 +01:00

b131a4db24 bug #1631: fix compilation with ARM NEON and clang, and cleanup the weird pshiftright_and_cast and pcast_and_shiftleft functions. 2018-11-27 23:45:00 +01:00

fa7fd61eda Unify SSE/AVX psin functions. 
It is based on the SSE version which is much more accurate, though very slightly slower.
This changeset also includes the following required changes:
 - add packet-float to packet-int type traits
 - add packet float<->int reinterpret casts
 - add faster pselect for AVX based on blendv

2c44c40114 First step toward a unification of packet log implementation, currently only SSE and AVX are unified. 
To this end, I added the following functions: pzero, pcmp_*, pfrexp, pset1frombits functions.

b80d9dd42e fix determination of number of registers on sse: 
__i386__ was not defined by MSVC 2010.
fixed as (2*sizeof(void*)).
also move that to SSE/ and let the default for unknown arch's be just 8.

88cd6885be Add a proof concept API to configure the blocking parameters at runtime. 
After validation of the final API I'll update the other products to use it.
