[Beignet] [PATCH V2 2/2] Add the test case for builtin abs() function
junyan.he at inbox.com
junyan.he at inbox.com
Thu Jun 27 02:01:12 PDT 2013
From: Junyan He <junyan.he at linux.intel.com>
All the integer value types check are supported.
Please use the case named compiler_abs_xxxx,
where xxxx means the data type such as int2, char4
