* (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.

| | | | | | | | hackish workarounds as gcc on ARM (both CodeSourcery 4.4.1 used and experimental 4.5) fail to ensure proper alignment with __attribute__((aligned(16))). This has to be fixed upstream to remove the workarounds.
* 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.
* 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?
* 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 ?
