7e2afe7e95 remove the __ARM_NEON__ check there since Konstantinos said he removed it but apparently didn't commit :) 2010-03-06 12:11:08 -05:00

2bd31d3fbc * include Macros.h much earlier: since it takes care of the alignment platform detection, it is needed before we do the vectorization stuff in Eigen/Core !! 
* kill EIGEN_DONT_ALIGN_HEAP option (one should use EIGEN_DONT_ALIGN)
* rename EIGEN_DONT_ALIGN_STACK to EIGEN_DONT_ALIGN_STATICALLY. hope it's a better name.

f03d95348d introduce EIGEN_DONT_ALIGN_STACK (disables alignment attributes) and EIGEN_DONT_ALIGN_HEAP (disables aligned malloc)... 
you can still use EIGEN_DONT_ALIGN to do both at once.

112c550b4a Added initial NEON support, most tests pass however we had to use some 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.

9334ed4444 on 64-bit systems, glibc's malloc returns 16-byte aligned ptrs, and we now take advantage of that. 2010-02-28 10:10:53 -05:00

a480e7e60f * fix ei_handmade_aligned_realloc (was calling realloc on wrong ptr) 
* add missing std::  (at least for QNX compatibility)
* add big comments to "structure" the file

ff8c2149c1 Added a generic reallocation implementation based on ei_aligned_malloc/_free. 
Rewrote ei_handmade_aligned_realloc such that it is now using std::realloc.
Reorganized functions in Memory.h for better readability.
Add missing <cerrno> include to Core (it's now required in Memory.h).

769641bc58 * Implement the ByOuterInner accessors 
* use them (big simplification in Assign.h)
* axe (Inner|Outer)StrideAtCompileTime that were just introduced
* ei_int_if_dynamic now asserts that the size is the expected one: adapt to that in Block.h
* add rowStride() / colStride() in DenseBase
* implement innerStride() / outerStride() everywhere needed

37ca4200b2 Piotr's patch was missing many occurences of size_t. So, 
using std::size_t;
This is the only way that we can ensure QCC support in the long term without having to think about it everytime.

25f8adfa6c * Fix bug #79: ei_alignmentOffset was assuming that ptr is multiple of 
sizeof(Scalar), and that assumption breaks with double on linux x86-32.
* Rename ei_alignmentOffset to ei_first_aligned
* Rewrite its documentation and part of its body
* The variant taking a MatrixBase doesn't need a separate size argument.

5cb779e5e1 * introduce ei_alignmentOffset(MatrixBase&,Integer) 
couldnt put it in Memory.h as it needs the definition of MatrixBase
* make Redux use it

6347b1db5b remove sentence "Eigen itself is part of the KDE project." 
it never made very precise sense. but now does it still make any?

b6c76c30cd apply patch from Hauke Heibel cleaning overloaded operator new/detete 2009-05-07 20:33:48 +00:00
Benoit Jacob
95bda5e6ab let the user disable alignment altogether by #defining EIGEN_DONT_ALIGN. 
Until now, the user had to edit the source code to do that.
Internally, add EIGEN_ALIGN that takes into account both EIGEN_DONT_ALIGN.and
EIGEN_ARCH_WANTS_ALIGNMENT. From now on, only EIGEN_ALIGN should be used to
test whether we want to align.

3009d79a1f * allow Matrix to be resized to 0 (solve a lot of troubles with 
some containers)
* new workaround for std::vector which is supposed to work for any
  classes having EIGEN_MAKE_ALIGNED_OPERATOR_NEW as discussed on ML

93a089adc8 disable alignment altogether outside of the platforms which potentially have SSE or AltiVec 
This should remove most portability issues to other platforms where data alignment issues (including
overloading operator new and new[]) can be tricky, and where data alignment is not needed in the first place.

f3d5ba0c1f the BSD's don't have aligned malloc after all 2009-02-02 13:22:19 +00:00

9849931500 eventually it turns out that our current 
EIGEN_WORK_AROUND_QT_BUG_CALLING_WRONG_OPERATOR_NEW_FIXED_IN_QT_4_5
is the right way to go for allowing placement new on a class having
overloaded operator new. Qt 4.5 won't add the :: prefix. (I still do not
understand how you can distinghish a placement new from an overloaded
operator new taking an allocator as argument...)

5f43a42ee7 * remove set(), revert to old behavior where = resizes 
* try to be clever in matrix ctors and operator=: be lazy when we can, always allow
  to copy rowvector into columnvector, check the template parameters,
  try to factor the code better
* add missing copy ctor in UnalignedType
* fix bug in the traits of DiagonalProduct
* renaming: EIGEN_TUNE_FOR_CPU_CACHE_SIZE
* update the dox a little

byte aligned, after discussion with Mark Davies.
