7dd81aad74 factorize default performance related settings to a single file 
included after the architecture specific files such that they
can be adapted by each platform.

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.

0f3d69b65e Provide "eigen" defines to decide which instruction set is used 
(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.

eb905500b6 significant speedup in the matrix-matrix products 2010-02-23 13:06:49 +01:00

4365a48748 Added an ei_linspaced_op to create linearly spaced vectors. 
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.

6db6774c46 * fix aliasing checks when the lhs is also transposed. At the same time, 
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

3ea1f97f69 Suppressed the warning for missing assignment generators (forgot that in the last submission). 
Commented Quake3's fast inverser sqrt in SSE's MathFunction header.

eb8f450071 Hey, finally the copyCoeff stuff is not only used to implement swap anymore :) 
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.

3979f6d8aa Let's try to stick to the original code, thus activate the fix of #62 only for 64 bit builds. 2009-11-04 15:49:22 +01:00

e2170b9f7e Direct access of the packet structs fixes bug #62 and doe not seem to

d41577819b we were already aligning to 16 byte boundary fixed-size objects that are 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.

a44f7cf440 re-enable the fast unaligned loads for gcc and icc using inline assembly 
(this allows to avoid incompatible pointer casts and to specify the dependency to the data explicitely)

it never made very precise sense. but now does it still make any?

a22ef7e1f3 for some reason passing the argument by const reference killed the perf 
(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.

17860e578c add SSE2 versions of sin, cos, log, exp using code from Julien 
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 ?
