Gael Guennebaud	1f5024332e	First part of a big refactoring of alignment control to enable the handling of arbitrarily aligned buffers. It includes: ... - AlignedBit flag is deprecated. Alignment is now specified by the evaluator through the 'Alignment' enum, e.g., evaluator<Xpr>::Alignment. Its value is in Bytes. - Add several enums to specify alignment: Aligned8, Aligned16, Aligned32, Aligned64, Aligned128. AlignedMax corresponds to EIGEN_MAX_ALIGN_BYTES. Such enums are used to define the above Alignment value, and as the 'Options' template parameter of Map<> and Ref<>. - The Aligned enum is now deprecated. It is now an alias for Aligned16. - Currently, traits<Matrix<>>, traits<Array<>>, traits<Ref<>>, traits<Map<>>, and traits<Block<>> also expose the Alignment enum.	2015-08-06 15:31:07 +02:00

Gael Guennebaud	972a535288	Remove aligned-on-scalar assert and fallback to non vectorized path at runtime (first_aligned already had this runtime guard)	2015-06-14 15:04:07 +02:00
Gael Guennebaud	834f66e9fc	Extend unit test of Map<> with stack allocated buffers and less trivial operations.	2015-04-24 10:10:19 +02:00
Benoit Steiner	7ed9441ea4	Reverted the definition of the EIGEN_ALIGN to its former meaning (i.e. a boolean) ... Created a new EIGEN_ALIGN_BYTES define to encode how the data should be aligned Fixed a few remaining alignment issues exposed when the Eigen code is compiled with avx enabled. Created a new EIGEN_ALIGN_DEFAULT define, which is set to the minimum alignment value required for the chosen instruction set. Use this value instead of EIGEN_ALIGN32 to preserve the existing alignment on SSE/Altivec/Neon.	2014-02-18 18:06:44 -08:00
Gael Guennebaud	c550a0e634	extend Map unit test to check buffers allocated on the stack	2013-11-21 10:39:47 +01:00
Gael Guennebaud	71cccf0ed8	Rename map unit test to mapped_matrix: without splitting unit tests, this created a "map" binary file in the include path, not a good idea!	2013-07-10 23:26:35 +02:00
