Ari Koivula fcb6fa6d4b Fix compilation error on PowerPC.
- 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.
2014-10-13 16:57:15 +03:00
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.
