NettetWhen tracing this assembly code, consider whether the data being accessed represents a pointer or a value. For example, the instruction at results in stack location sp + 28 containing a variable of type int, which is initially set to 0.In contrast, the argument stored at location sp + 8 is the first argument to the function (array), which is of type int … NettetA shift moves the bits in each element of a vector left or right. Bits that fall off the left or right of each element are discarded. These discarded bits are not shifted to adjacent elements. The number of bits to shift can be specified as follows: With a single immediate literal encoded in the instruction With a shift vector
