From 8d067ab2f631b147745e5eb3cf85056042c1439e Mon Sep 17 00:00:00 2001 From: Kota Tsuyuzaki Date: Thu, 3 Nov 2016 04:54:19 -0700 Subject: ISA-L Cauchy support This is for supporting ISA-L cauchy based matrix. The difference from isa_l_rs_vand is only the matrix to use the encode/decode calculation. As a known issue, isa_l_rs_vand backend has constraint for the combinations of the available fragment to be able to decode/reconstuct. (See related change in detail) To avoid the constraint, this patch adds another isa-l backend to use cauchy matrix and keep the backward compatibility, this is in another isa_l_rs_cauchy namespace. For implementation consieration, the code is almost same except the matrix generation fucntion so that this patch makes isa_l_common.c file for gathering common fucntions like init/encode/decode/reconstruct. And then the common init funciton takes an extra args "gen_matrix_func_name" for entry point to load the fucntion by dlsym from isa-l .so file.
