Incompatible type vector assignment error in Clang Rev 3.1

Hi All,

I am encountering the following error
“assigning to ‘uint4’ from incompatible type ‘int attribute((ext_vector_type(4)))’”

for code, p = q < (uint4)2; where p and q are of type uint4

The explicit type casting before assignement [p = (unit4)(q < (uint4)2)] resolves the error.

In Clang Rev 2.9, there was no error for such code.
Avoiding this implicit conversion of ‘int4’ to ‘uint4’ is intentional in Clang Rev3.1 OR am i missing something.
