WebIn C++, shift is only well-defined if you shift a value less steps than the size of the type. If int is 32 bits, then only 0 to, and including, 31 steps is well-defined.. So, why is this? If you take a look at the underlying hardware that performs the shift, if it only has to look at the lower five bits of a value (in the 32 bit case), it can be implemented using less logical … WebFeb 22, 2024 · I want to overload the bitshift operator for a uint32x4_t defined on ARM systems in arm_neon.h. struct uint32x4_t { uint32_t val[4]; }; This should be done with a call to a SIMD function, which expects the value to shift and a constant immediate: uint32x4_t simdShift(uint32x4_t, constant_immediate); shift.h
