Function LLVMRustCreateRangeAttribute 

Source 
pub(crate) unsafe extern "C" fn LLVMRustCreateRangeAttribute(
    C: &Context,
    NumBits: c_uint,
    LowerWords: *const u64,
    UpperWords: *const u64,
) -> &Attribute
Expand description

ยงSafety

  • Each of LowerWords and UpperWords must point to an array that is long enough to fully define an integer of size NumBits, i.e. each pointer must point to NumBits.div_ceil(64) elements or more.
  • The implementation will make its own copy of the pointed-to u64 values, so the pointers only need to outlive this function call.
