About the Advanced SIMD and floating-point support
The Cortex‑A76 floating-point implementation:
- Does not generate floating-point exceptions.
Implements all scalar operations in hardware with support for all combinations of:
- Default Not a Number (NaN) modes.
The Arm®v8‑A architecture does not define a separate version number for its Advanced SIMD and floating-point support in the AArch64 execution state because the instructions are always implicitly present.
