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 Koivula 3f00592b96 Separate strategyselector debug prints from _DEBUG.
- I only want to see the strategy stuff.

Ari Koivula 1c97a10a6d Move intra SAD and SATD functions under strategies. 2014-06-16 12:13:41 +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.

Laurent Fasnacht 5ed69b063b Strategy selector for array_checksum, basic implementation using precomputed 256*256 block with larger accesses than byte 2014-06-03 07:42:22 +02:00
Ari Koivula 42295d3cb9 Pass preprocessor defines for supported intrinsics in VS2010 explicitly.
- _M_IX86_FP defines whether VS should generate code using SSE or SSE2
  instructions. It isn't correct to use it to check whether optional runtime
  optimizations should be compiled in. It's also not defined at all in 64-bit
  mode.

- So let's just keep it simple and give a list of everything that is supported
  as release optimizations. It's not clear from the documentation if all of
  these are really supported. It just list a bunch of intrinsics from these
  that are.

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.
