    28== Disable auto vectorization == 
    39In the section 6.7.2 (187 page) in the OpenCL Specification Version: 1.1 (Revision: 33), "__attribute__((vec_type_hint(<typen>))" is described. This hint controls the autovectorizer in the compiler for OpenCL C. I tested this feature by dumping the assembly code for a kernel (heavily using "float8" ) targeted for AVX instructions with Intel SDK (version 1.5).
