ec: Removed SSE2 dependency 2014-09-12T05:44:12+00:00 Xavier Hernandez xhernandez@datalab.es 2014-08-04T18:50:31+00:00 26be0b3a9f334f33f1a6e53706045eb02983d713 This patch implements the Galois Field multiplications using pure C code without any assembler support. This makes the ec xlator portable to other architectures. In the future it will be possible to use an optimized implementation of the multiplications using architecture dependent facilities (it will be automatically detected and configured). To allow bricks with different machine word sizes to be able to work seamlessly in the same volume, the minimum fragment length to be stored in any brick has been fixed to 512 bytes. Otherwise, different implementations will corrupt the data (SSE2 used 128 bytes, while new implementation would have used 64). This patch also removes the '-msse2' option added on patch http://review.gluster.org/8395/ Change-Id: Iaf6e4ef3dcfda6c68f48f16ca46fc4fb61a215f4 BUG: 1125166 Signed-off-by: Xavier Hernandez <xhernandez@datalab.es> Reviewed-on: http://review.gluster.org/8413 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Dan Lambright <dlambrig@redhat.com>
