tldr: GCC now supports FRINT32X/Z and FRINT64X/Z instructions in SVE2.2 and SME2.2, which round floating-point numbers to 32-bit or 64-bit integers.

GCC now supports FRINT32X/Z and FRINT64X/Z instructions in SVE2.2 and SME2.2, which round floating-point numbers to 32-bit or 64-bit integers. The new intrinsics and RTL patterns have been implemented, along with a standard set of ASM tests.
