Signed Maximum across Vector.
- Is the destination width specifier, and can be one of the values shown in Usage.
- Is the number of the SIMD and FP destination register.
- Is the name of the SIMD and FP source register.
- Is an arrangement specifier, and can be one of the values shown in Usage.
Signed Maximum across Vector. This instruction compares all the vector elements in the source SIMD and FP register, and writes the largest of the values as a scalar to the destination SIMD and FP register. All the values in this instruction are signed integer values.
Depending on the settings in the CPACR_EL1, CPTR_EL2, and CPTR_EL3 registers, and the current Security state and Exception level, an attempt to execute the instruction might be trapped.
