* Let's try to stick to the original code, thus activate the fix of #62 only ↵Gravatar Hauke Heibel2009-11-04

* Direct access of the packet structs fixes bug #62 and doe not seem toGravatar Hauke Heibel2009-11-04

* we were already aligning to 16 byte boundary fixed-size objects that are ↵Gravatar Benoit Jacob2009-10-05
| | | | | | | | multiple of 16 bytes; now we also align to 8byte boundary fixed-size objects that are multiple of 8 bytes. That's only useful for now for double, not e.g. for Vector2f, but that didn't seem to hurt. Am I missing something? Do you prefer that we don't align Vector2f at all? Also, improvements in test_unalignedassert.
* clean the commented asm instructions because now I'm sureGravatar Gael Guennebaud2009-09-17
| | | | the previous fix is ok

| | | | * workaround GCC bad implementation of _mm_set1_p*

|
* only disable the inline ASM if we're NEITHER gcc nor icc. right ??Gravatar Benoit Jacob2009-06-26
|
* re-enable the fast unaligned loads for gcc and icc using inline assemblyGravatar Gael Guennebaud2009-06-24
| | | | (this allows to avoid incompatible pointer casts and to specify the dependency to the data explicitely)
* use the slower unaligned load intrinsics in ei_ploadu because GCC mess up ↵Gravatar Gael Guennebaud2009-06-23
| | | | with my tricks
* remove sentence "Eigen itself is part of the KDE project."Gravatar Benoit Jacob2009-05-22
| | | | it never made very precise sense. but now does it still make any?

|
* * fix the binary bloat issue, Rohit's idea was the good oneGravatar Benoit Jacob2009-04-06
| | | | * a few dox fixes (alloc routines do return 0 on error) and forgot to update version number in CMakeLists
* add vectorization of sqrt for floatGravatar Gael Guennebaud2009-03-27
|
* for some reason passing the argument by const reference killed the perfGravatar Gael Guennebaud2009-03-25
| | | | | (in the packet version of sin, cos, exp, lop), so let's pass them by value. Also, improve the perf of ei_plog by reducing dependencies.
* add SSE2 versions of sin, cos, log, exp using code from JulienGravatar Gael Guennebaud2009-03-25
| | | | | | | | Pommier. They are for float only, and they return exactly the same result as the standard versions in about 90% of the cases. Otherwise the max error is below 1e-7. However, for very large values (>1e3) the accuracy of sin and cos slighlty decrease. They are about 3 or 4 times faster than 4 calls to their respective standard versions. So, is it ok to enable them by default in their respective functors ?
* ei_pnegate implemented for AltiVecGravatar Konstantinos A. Margaritis2009-03-20

* add vectorization of unary operator-() (the AltiVec version is probablyGravatar Gael Guennebaud2009-03-20
| | | | broken)
* add the vectorization of absGravatar Gael Guennebaud2009-03-09

* slight optimization of SSE base integer mul (thanks to Rohit Garg)Gravatar Gael Guennebaud2009-03-08

* Add COMPONENT DevelGravatar Laurent Montel2009-02-23

* no reason for 3 vec_mins, 2 are enough apparently in ei_predux_minGravatar Konstantinos A. Margaritis2009-02-12
|
* modified ei_predux_min/max to actually use altivec instructionsGravatar Konstantinos A. Margaritis2009-02-12
|
* * exit Sum.h, exit Prod.h, welcome vectorization of redux() !Gravatar Gael Guennebaud2009-02-12

* * fix a vectorization issue in ProductGravatar Gael Guennebaud2008-12-19
| | | | | | * use _mm_malloc/_mm_free on other platforms than linux of MSVC (eg., cygwin, OSX) * replace a lot of inline keywords by EIGEN_STRONG_INLINE to compensate for poor MSVC inlining
* Hopefully fix compilation of SSE Packetmath with MSVC.Gravatar Benoit Jacob2008-12-16
| | | | | The reason why we didn't realize until now that it didn't compile at all with MSVC is that before today with MSVC the SSE2 detection didn't work.
* Missing inline keywords in AltiVec/PacketMath were making Avogadro failGravatar Benoit Jacob2008-08-27

* remove double ;Gravatar Benoit Jacob2008-08-27

| | | | * fix warning in SolveTriangular
* Added a ei_palign function align a packet from two others.Gravatar Gael Guennebaud2008-08-03
| | | | | This allows much faster code dealing with unligned as in the updated matrix-vector product functions.
* Optimizations:Gravatar Gael Guennebaud2008-08-01
| | | | | | | | * faster matrix-matrix and matrix-vector products (especially for not aligned cases) * faster tridiagonalization (make it using our matrix-vector impl.) Others: * fix Flags of Map * split the test_product to two smaller ones
