drivers/gpu/drm/i915/i915_reg.h:90:shift-overflow problem ?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello there,

drivers/gpu/drm/i915/i915_reg.h:90:28: warning: result of ‘65535 <<
20’ requires 37 bits to represent, but ‘int’ only has 32 bits
[-Wshift-overflow=]

Source code is

#define   BSM_MASK (0xFFFF << 20)

Maybe better code

#define   BSM_MASK (((unsigned long) 0xFFFF) << 20)


Regards

David Binderman
