From: Ranbir Singh <ranbir.sin...@dell.com> Line number 1348 does contain a typecast with UINT32, but it is after all the operations (16-bit left shift followed by OR'ing) are over. To avoid any SIGN_EXTENSION, typecast the intermediate result after 16-bit left shift operation immediately with UINT32.
