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. } @encoding (T1) { @word 1 1 1 1 1 1 1 1 1 D(1) 1 1 size(2) 0 0 Vd(4) 0 1 1 1 0 Q(1) M(1) 0 Vm(4) @syntax { @subid 2699 @assert { Q == 1 size == 0 } @conv { qwvec_D = QuadWordVector(D:Vd) qwvec_M = QuadWordVector(M:Vm) } @asm vqabs.s8 qwvec_D qwvec_M } @syntax { @subid 2700 @assert { Q == 1 size == 1 } @conv { qwvec_D = QuadWordVector(D:Vd) qwvec_M = QuadWordVector(M:Vm) } @asm vqabs.s16 qwvec_D qwvec_M } @syntax { @subid 2701 @assert { Q == 1 size == 10 } @conv { qwvec_D = QuadWordVector(D:Vd) qwvec_M = QuadWordVector(M:Vm) } @asm vqabs.s32 qwvec_D qwvec_M } @syntax { @subid 2702 @assert { Q == 0 size == 0 } @conv { dwvec_D = DoubleWordVector(D:Vd) dwvec_M = DoubleWordVector(M:Vm) } @asm vqabs.s8 dwvec_D dwvec_M } @syntax { @subid 2703 @assert { Q == 0 size == 1 } @conv { dwvec_D = DoubleWordVector(D:Vd) dwvec_M = DoubleWordVector(M:Vm) } @asm vqabs.s16 dwvec_D dwvec_M } @syntax { @subid 2704 @assert { Q == 0 size == 10 } @conv { dwvec_D = DoubleWordVector(D:Vd) dwvec_M = DoubleWordVector(M:Vm) } @asm vqabs.s32 dwvec_D dwvec_M } } @encoding (A1) { @word 1 1 1 1 1 1 1 1 1 D(1) 1 1 size(2) 0 0 Vd(4) 0 1 1 1 0 Q(1) M(1) 0 Vm(4) @syntax { @subid 2705 @assert { Q == 1 size == 0 } @conv { qwvec_D = QuadWordVector(D:Vd) qwvec_M = QuadWordVector(M:Vm) } @asm vqabs.s8 qwvec_D qwvec_M } @syntax { @subid 2706 @assert { Q == 1 size == 1 } @conv { qwvec_D = QuadWordVector(D:Vd) qwvec_M = QuadWordVector(M:Vm) } @asm vqabs.s16 qwvec_D qwvec_M } @syntax { @subid 2707 @assert { Q == 1 size == 10 } @conv { qwvec_D = QuadWordVector(D:Vd) qwvec_M = QuadWordVector(M:Vm) } @asm vqabs.s32 qwvec_D qwvec_M } @syntax { @subid 2708 @assert { Q == 0 size == 0 } @conv { dwvec_D = DoubleWordVector(D:Vd) dwvec_M = DoubleWordVector(M:Vm) } @asm vqabs.s8 dwvec_D dwvec_M } @syntax { @subid 2709 @assert { Q == 0 size == 1 } @conv { dwvec_D = DoubleWordVector(D:Vd) dwvec_M = DoubleWordVector(M:Vm) } @asm vqabs.s16 dwvec_D dwvec_M } @syntax { @subid 2710 @assert { Q == 0 size == 10 } @conv { dwvec_D = DoubleWordVector(D:Vd) dwvec_M = DoubleWordVector(M:Vm) } @asm vqabs.s32 dwvec_D dwvec_M } }
