* mixing types in product step 2:Gravatar Gael Guennebaud2010-07-11
| | | | | | | | * pload* and pset1 are now templated on the packet type * gemv routines are now embeded into a structure with a consistent API with respect to gemm * some configurations of vector * matrix and matrix * matrix works fine, some need more work...

* (proper commit this time)Gravatar Konstantinos Margaritis2010-04-24
| | | | | | | replaced _mm_prefetch in GeneralBlockPanelKernel.h, with ei_prefetch() inline function. Implemented NEON and AltiVec versions, copied SSE version over from GeneralBlockPanelKernel.h. Also in GCC case (or rather !_MSC_VER) it's implemented using __builtin_prefetch(). NEON managed to give a small but welcome boost, 0.88GFLOPS -> 0.91GFLOPS.

| | | | | | | | | | | | (sse3, ssse3 and sse4), independantly from the compiler. Only those defines should be used in other places, and the user can rely on those to know which sets are used.

* Added an ei_linspaced_op to create linearly spaced vectors.Gravatar Hauke Heibel2010-01-26
| | | | | | | | | Added setLinSpaced/LinSpaced functionality to DenseBase. Improved vectorized assignment - overcomes MSVC optimization issues. CwiseNullaryOp is now requiring functors to offer 1D and 2D operators. Adapted existing functors to the new CwiseNullaryOp requirements. Added ei_plset to create packages as [a, a+1, ..., a+size]. Added more nullaray unit tests.
* Fixed conservativeResize.Gravatar Hauke Heibel2010-01-11

| | | | | | | | | | | | significantly simplify the code of these checks while extending them to catch much more expressions! * move the enabling/disabling of vectorized sin/cos to the architecture traits

* | Hey, finally the copyCoeff stuff is not only used to implement swap anymore :)Gravatar Gael Guennebaud2009-11-20
|/ | | | | | Add an internal pseudo expression allowing to optimize operators like +=, *= using the copyCoeff stuff. This allows to easily enforce aligned load for the destination matrix everywhere.

* 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

* re-enable the fast unaligned loads for gcc and icc using inline assemblyGravatar Gael Guennebaud2009-06-24

* 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 ?
