  Message : Fix signed integer overflow in GLSL preprocessor left shift Signed integer overflow is undefined in C++, whereas unsigned integer overflow is not. Always cast left shift operand to unsigned to avoid UB. On common compilers, the behavior was already the same before this patch, so this patch is done mostly for the benefit of automated fuzz testing.
