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 1 Q(1) M(1) 0 Vm(4) @syntax { @subid 1869 @assert { Q == 1 size == 0 } @conv { qwvec_D = QuadWordVector(D:Vd) qwvec_M = QuadWordVector(M:Vm) } @asm vqneg.s8 qwvec_D qwvec_M } @syntax { @subid 1870 @assert { Q == 1 size == 1 } @conv { qwvec_D = QuadWordVector(D:Vd) qwvec_M = QuadWordVector(M:Vm) } @asm vqneg.s16 qwvec_D qwvec_M } @syntax { @subid 1871 @assert { Q == 1 size == 10 } @conv { qwvec_D = QuadWordVector(D:Vd) qwvec_M = QuadWordVector(M:Vm) } @asm vqneg.s32 qwvec_D qwvec_M } @syntax { @subid 1872 @assert { Q == 0 size == 0 } @conv { dwvec_D = DoubleWordVector(D:Vd) dwvec_M = DoubleWordVector(M:Vm) } @asm vqneg.s8 dwvec_D dwvec_M } @syntax { @subid 1873 @assert { Q == 0 size == 1 } @conv { dwvec_D = DoubleWordVector(D:Vd) dwvec_M = DoubleWordVector(M:Vm) } @asm vqneg.s16 dwvec_D dwvec_M } @syntax { @subid 1874 @assert { Q == 0 size == 10 } @conv { dwvec_D = DoubleWordVector(D:Vd) dwvec_M = DoubleWordVector(M:Vm) } @asm vqneg.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 1 Q(1) M(1) 0 Vm(4) @syntax { @subid 1875 @assert { Q == 1 size == 0 } @conv { qwvec_D = QuadWordVector(D:Vd) qwvec_M = QuadWordVector(M:Vm) } @asm vqneg.s8 qwvec_D qwvec_M } @syntax { @subid 1876 @assert { Q == 1 size == 1 } @conv { qwvec_D = QuadWordVector(D:Vd) qwvec_M = QuadWordVector(M:Vm) } @asm vqneg.s16 qwvec_D qwvec_M } @syntax { @subid 1877 @assert { Q == 1 size == 10 } @conv { qwvec_D = QuadWordVector(D:Vd) qwvec_M = QuadWordVector(M:Vm) } @asm vqneg.s32 qwvec_D qwvec_M } @syntax { @subid 1878 @assert { Q == 0 size == 0 } @conv { dwvec_D = DoubleWordVector(D:Vd) dwvec_M = DoubleWordVector(M:Vm) } @asm vqneg.s8 dwvec_D dwvec_M } @syntax { @subid 1879 @assert { Q == 0 size == 1 } @conv { dwvec_D = DoubleWordVector(D:Vd) dwvec_M = DoubleWordVector(M:Vm) } @asm vqneg.s16 dwvec_D dwvec_M } @syntax { @subid 1880 @assert { Q == 0 size == 10 } @conv { dwvec_D = DoubleWordVector(D:Vd) dwvec_M = DoubleWordVector(M:Vm) } @asm vqneg.s32 dwvec_D dwvec_M } }
