Ari Koivula 75a137c1e9 Add --cpuid parameter to disable runtime optimizations. 2014-10-16 12:01:36 +03:00
Ari Lemmetti 0beb278f5b Partial butterfly strategy is now called DCT strategy. Made changes to transform functions in preparation for optimizations. 
-Moved fast_forward_dst and fast_inverse_dst to DCT strategies

Ari Lemmetti faccc4f09b Partial butterfly functions now utilize the strategy selector 2014-07-31 13:25:28 +03:00
Ari Koivula d5a77be4b8 Fix avx detection for gcc. 
- GCC doesn't support _xgetbv intrinsic so we have to use inline assembler.

Ari Koivula d7abe6a7c2 Address compilation warning. 
strategyselector.c:170:10: error: ‘__get_cpuid’ is static but used in inline function ‘get_cpuid’ which is not static [-Werror]
   return __get_cpuid(level, eax, ebx, ecx, edx);

Laurent Fasnacht 84d34c2655 Fix compilation on non-intel 2014-06-16 11:24:02 +02:00
Ari Koivula 3f00592b96 Separate strategyselector debug prints from _DEBUG. 
- I only want to see the strategy stuff.

Ari Koivula fcce6ae823 Fix printing of AVX2 capability. 2014-06-14 01:24:19 +03:00
Ari Koivula a49ba2633a Add OS and CPU detection for AVX2 and AVX. 2014-06-13 16:57:53 +03:00
Ari Koivula 1de102be61 Move strategies to their own compilation units. 
- Enforces a little bit more hierarchy. Compilation units are in strategies
  and whatever inline includes they have are in a folder with the same name
  as the strategy.

Marko Viitanen 792a5a5dd1 Small fix for __get_cpuid() 2014-05-30 08:37:03 +03:00
Laurent Fasnacht 4f86919d75 Get rid of assembly cpuid for x86, compilation works for powerpc 2014-05-28 15:04:00 +02:00
Ari Koivula bd7e021742 Modify strategyselector to work with VS2010. 
- VS doesn't have snprintf.

- VS doesn't support GCC attributes.

- Add defines for __SSE__ and __SSE2__ on VS.
