That is one instruction and a more accurate definition of it would be “match x86 float to integer conversion”. It’s not a complex instruction, essentially using an explicit set of non default rounding flags. All in order to match what x86 does. So if that instruction does help arm, it is only in getting rid of an advantage x86 had in being the dominant arch 25 years ago.
