@title VABD (floating-point)
@id 274
@desc {
Vector Absolute Difference (floating-point) subtracts the elements of one vector from the corresponding elements of another vector, and places the absolute values of the results in the elements of the destination vector. Operand and result elements are all single-precision floating-point numbers. 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 that is not also available as a VFP instruction, see Conditional execution on page A8-288.
