[Beignet] [PATCH] [PATCH_V3]Fix compile warnings for CLANG compiler

Lv Meng meng.lv at intel.com
Wed Aug 13 20:36:15 PDT 2014


1.fix data structure redefine warnings.
2.fix 'data' with variable sized type 'union<*>' not at the end of a class warning(in immediate.hpp).
3.fix implicitly conversion warning.
4.fix explicitly assigning a variable type warning.
5.fix comparison of unsigned expression < 0 is always false warning(in cl_api.c).
6.fix unused function warning(in compiler_saturate_sub.cpp).
