@title VNEG

@id 336

@desc {

	Vector Negate negates each element in a vector, and places the results in a second vector. The floating-point version only inverts the sign bit. Depending on settings in the CPACR, NSACR, HCPTR, and FPEXC 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 general controls of CP10 and CP11 functionality on page B1-1230 and Summary of access controls for Advanced SIMD functionality on page B1-1232 summarize 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.
