GCC now supports Advanced SIMD and Floating-point (ACLE) extensions for AArch64, specifically for the SVE AES2 features. This includes adding built-in functions and RTL patterns for multi-vector AES indexed instructions and 128-bit PMULL/PMLAL pairs. Corresponding feature macros for SVE AES2 and SSVE AES have also been defined.
