	Vector Saturating Rounding Shift Left takes each element in a vector, shifts them by a value from the least significant byte of the corresponding element of a second vector, and places the results in the destination vector. If the shift value is positive, the operation is a left shift. Otherwise, it is a right shift. For truncated results see VQSHL (register) on page A8-1014. The first operand and result elements are the same data type, and can be any one of: • 8-bit, 16-bit, 32-bit, or 64-bit signed integers • 8-bit, 16-bit, 32-bit, or 64-bit unsigned integers. The second operand is a signed integer of the same size. If any of the results overflow, they are saturated. The cumulative saturation bit, FPSCR.QC, is set if saturation occurs. For details see Pseudocode details of saturation on page A2-44. Depending on settings in the CPACR, NSACR, and HCPTR registers, and the security state and mode in which the instruction is executed, an attempt to execute the instruction might be UNDEFINED, or trapped to Hyp mode. Summary of access controls for Advanced SIMD functionality on page B1-1232 summarizes these controls. ARM deprecates the conditional execution of any Advanced SIMD instruction encoding that is not also available as a VFP instruction encoding, see Conditional execution on page A8-288.
