Function redox::intrinsics::i32_sub_with_overflow

pub unsafe extern "rust-intrinsic" fn i32_sub_with_overflow(x: i32, y: i32) -> (i32, bool)

Unstable (core_intrinsics)

: intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

Performs checked i32 subtraction.
