6a5a13e394 The pfirst hack is needed also on msvc 2010 as it gets completely nuts, even though it doesnt segfault as msvc 2008 did 2011-02-09 15:13:23 -05:00

5887a086cf fix SSE3 issue (infinite loop after the ei_ => internal change) - this fix bug #174 2011-02-03 17:55:24 +01:00

e05c79cbd8 Fixed NEON compilation errors, changed float-abi back to softfp (which is the most used right now). 
Some complex tests appear to segfault, needs a more careful look.

7bc8e3ac09 Initial fixes for bug #85. 
Renamed meta_{true|false} to {true|false}_type, meta_if to conditional, is_same_type to is_same, un{ref|pointer|const} to remove_{reference|pointer|const} and makeconst to add_const.
Changed boolean type 'ret' member to 'value'.
Changed 'ret' members refering to types to 'type'.
Adapted all code occurences.

b80d9dd42e fix determination of number of registers on sse: 
__i386__ was not defined by MSVC 2010.
fixed as (2*sizeof(void*)).
also move that to SSE/ and let the default for unknown arch's be just 8.

f8678272a4 mixing types step 3: 
- improve support of colmajor by vector and matrix - matrix

ff96c94043 mixing types in product step 2: 
* 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...

6dcd373b9d let ei_pset1 use _mm_loaddup_pd. Not a significant speed improvement, but also not a speed regression, and replaces 3 instructions by 1 single instruction. 2010-07-09 18:51:17 -04:00

d9e134c73c Altivec port of Complex.h. 
Note: For some reason g++ 4.4 is >200% slower than g++ 4.3 on altivec code.
The same benchmark (bench_gemm) was tested, on the same hardware/OS (G4/Debian testing),
with same CFLAGS. With some code reorganizing I managed to get some minor gain
on 4.4, but I just could not reach 4.3 speed. This is most likely a bug, but I'm waiting
to see if it's fixed on 4.5. I'll look into this a bit more.

2066ed91de enabling aligned loads/store for complex<double> is much more tricky,
