Ari Lemmetti b30f17d4b8 Add fractional pixel sampling for chroma 2015-08-10 17:55:37 +03:00
Ari Lemmetti 650dd7d840 Use pixels_blit to copy neccessary pixels. 2015-08-10 17:52:00 +03:00
Ari Lemmetti 01f40ec104 Add fractional pixel sampling for luma 2015-08-10 17:51:48 +03:00
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.

 2015-07-31 17:35:16 +03:00
Ari Koivula 0740a73fbb Clean up Makefile. 
- Move stuff around.

 2015-07-31 15:57:05 +03:00
Ari Koivula beec2705b1 Add cli, lib-shared and lib-static to Makefile. 2015-07-31 15:57:05 +03:00
Ari Koivula 24b3306325 Fix incorrect pattern rules in Makefile. 
- Having more than one rule in a pattern rule means that both of those files
  are created at the same time with the rule. This only worked for debug,
  because debug build was never done in the same invocation as release build.
 2015-07-31 14:36:45 +03:00
Ari Koivula 1c27f67963 Remove -flto. 
- Always use the compiler to invoke the linker. Clang will give additional
  parameters to the linker when compiled with -flto.
- Giving a different optimization level to linker did not make any difference
  in gcc-5.1.1.
 2015-07-31 14:36:26 +03:00
Ari Koivula 54b1be341e Don't compile executable with PIC. 
- It's required for .so and .dylib, but not for .dll or the executable.
- It might be better to use libtool for this, but I'm not ready to go that
  far yet.

 2015-07-28 11:42:46 +03:00
Ari Koivula 2211b90a24 Move comments for defines to a different line.

prepending "./" to the tests recipe.
 2015-07-17 10:07:24 +03:00
Luca Barbato 56ff1c7805 build: Drop the non-standard -t

Ari Koivula c94d91061c Merge branch 'cpuid-fix' 2015-07-09 11:40:46 +03:00
Arttu Ylä-Outinen 8550c6ccd8 Fix AVX2 detection. 
Replaces calls to __get_cpuid by __cpuid_count on gcc and clang and
calls to __cpuid by __cpuidex on MSVC. Unlike __get_cpuid and __cpuid,
__cpuid_count and __cpuidex set the ecx register which is required for
AVX2 detection.
 2015-07-09 11:20:37 +03:00
Ari Koivula 9acf7795a2 Refactor cpuid capability detection. 
- Moved cpuid data to a struct to make it easier to group data from one
  cpuid call together.
- Renamed the bit masks to make it harder to mask the wrong register or
  cpuid.
- Remove the .byte trick. We don't really need to support such ancient
  compilers?
 2015-07-09 11:20:37 +03:00
Arttu Ylä-Outinen e69088026e Write slice header before joining child streams. 
The lengths of the leaf streams must be available when the slice header
is written. Writing the header before joining child streams removes the
need to copy leaf bitstreams instead of moving them.
