FCMLT (vector, zero)
Floating-point Compare Less than zero (vector).
T, #0.0 ; Vector half precision
T, #0.0 ; Vector single-precision and double-precision
- Is the name of the SIMD and FP destination register
For the vector half precision variant: is an arrangement specifier:
- Vector half precision
Can be one of
- Vector single-precision and double-precision
Can be one of
- Is the name of the SIMD and FP source register
Architectures supported (vector)
Supported in ARMv8.2 and later.
Floating-point Compare Less than zero (vector). This instruction reads each floating-point value in the source SIMD and FP register and if the value is less than 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.
This instruction can generate a floating-point exception. Depending on the settings in FPCR, the exception results in either a flag being set in FPSR, or a synchronous exception being generated. For more information, see Floating-point exception traps in the ARM Architecture Reference Manual ARMv8, for ARMv8-A architecture profile.
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.
