VMLS (integer)

Vector Multiply Subtract multiplies corresponding elements in two vectors, and subtracts the products from the corresponding elements of the destination vector.

Depending on settings in the CPACR, NSACR, and HCPTR registers, and the Security state and PE mode in which the instruction is executed, an attempt to execute the instruction might be undefined, or trapped to Hyp mode. For more information see Enabling Advanced SIMD and floating-point support.

It has encodings from the following instruction sets: A32 ( A1 ) and T32 ( T1 ) .

A1

if size == '11' then UNDEFINED; if Q == '1' && (Vd<0> == '1' || Vn<0> == '1' || Vm<0> == '1') then UNDEFINED; constant add = (op == '0'); constant long_destination = FALSE; constant unsigned = FALSE; // "Don't care" value: TRUE produces same functionality constant esize = 8 << UInt(size); constant elements = 64 DIV esize; constant d = UInt(D:Vd); constant n = UInt(N:Vn); constant m = UInt(M:Vm); constant regs = if Q == '0' then 1 else 2;

T1

if size == '11' then UNDEFINED; if Q == '1' && (Vd<0> == '1' || Vn<0> == '1' || Vm<0> == '1') then UNDEFINED; constant add = (op == '0'); constant long_destination = FALSE; constant unsigned = FALSE; // "Don't care" value: TRUE produces same functionality constant esize = 8 << UInt(size); constant elements = 64 DIV esize; constant d = UInt(D:Vd); constant n = UInt(N:Vn); constant m = UInt(M:Vm); constant regs = if Q == '0' then 1 else 2;
