Ari Koivula 0c3c93d456 Optimize intra SAD intrinsics.
- Added 64x64 version for completeness.
- With the exception of 16x16, these were all slightly slower than the ASM
  versions, as measured by "kvazaar_test -s speed -t intra_sad", but now they
  are on par or slightly faster.
- None of these actually use any AVX2 intrinsics, and probably never will,
  unless someone adds an interface for doing more than one block at a time,
  in which case the non-destructive versions might come in handy.

Ari Koivula d7383ccb25 Change license to LGPL.
- Everyone who has contributed code to the project has been asked to license
  their contributions under LPGL and they have agreed.

- COPYING file changed to say LGPLv2.1 instead of GPLv2.

- GPL changed to LGPL in the header of every single file that a header and
  header added to the few that were missing one.

- Also.. Happy new year!

- Need abs from stdlib.
2014-10-21 18:14:32 +03:00
Ari Koivula 55ab08c213 Fix incorrect const qualifiers.
- Change input pointers to const in dct-generic, like they should have been.
- Fixes compilation error on GCC.

Ari Koivula 8a5b24bcbe Remove usages of GCC __attribute__.
- To allow clang to compile, as it doesn't according to #58.
- The target attributes are not needed anymore due to makefile handling
  targetting now.
- The __attribute__((unused)) used for debugging. I don't know if clang
  supports this attribute or not but it doesn't seem very important so
  I'm removing it just in case.

Ari Koivula d893a489d6 Fix mingw compilation issue.
strategies/avx2/dct-avx2.c:334:25: error: pasting "g_dct_16" and "[" does
not give a valid preprocessing token

- The [ is not part of the token so compilation failed on mingw GCC 4.9.1.
- Fixes #86.
