driver version 10.1, the following line of GLSL code:
uint k = 3367900313U;
gives me Syntax error ERROR___INTEGER_CONST_OVERFLOW, even though the unsigned constant is within 32 bits. Seems like the GLSL compiler rejects unsigned constants with the highest bit set, as if they were signed.
Writing it as
uint k = 0xC8BE1499U;
there is an overflow issue indeed in the glsl parser. we will fix it.
