The NEON SHA1 intrinsics, also associated with the FEAT_SHA2 feature, have been migrated to GCC’s pragma-based framework. This change includes the addition of assembly tests for each intrinsic to verify their correct operation. Consequently, existing builtin functions and definitions have been removed and replaced by the new framework’s approach.
