6 ; z10 doesn't have native support for unsigned fp-to-i32 conversions;
7 ; they were added in z196 as the Convert to Logical family of instructions.
8 ; Promoting to i64 doesn't generate an inexact condition for values that are
9 ; outside the i32 range but in the i64 range, so use the default expansion.
