This update integrates the ARMv8.6-A FEAT_FPRCVT extension into GCC, introducing new support for floating-point to integer and integer to floating-point conversions. The change includes adding a new macro definition, updating instruction definition files, and expanding support for various conversion patterns. This enables more direct and potentially faster compilation of code using these specialized floating-point conversion operations on AArch64 targets that support the feature.
