20.23 CMLE (vector, zero)

Compare signed Less than or Equal to zero (vector).

Syntax

CMLE Vd.T, Vn.T, #0

Where:

Vd
Is the name of the SIMD and FP destination register.
T
Is an arrangement specifier, and can be one of 8B, 16B, 4H, 8H, 2S, 4S or 2D.
Vn
Is the name of the SIMD and FP source register.

Usage

Compare signed Less than or Equal to zero (vector). This instruction reads each vector element in the source SIMD and FP register and if the signed integer value is less than or equal to zero sets every bit of the corresponding vector element in the destination SIMD and FP register to one, otherwise sets every bit of the corresponding vector element in the destination SIMD and FP register to zero.

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.
