pub unsafe fn __hle_release_compare_exchange_n2(
    ptr: *mut u16, 
    oldp: *mut u16, 
    newv: u16
) -> bool

Atomically compare-and-swap with 'HLE Release' memory ordering. This compares the content of ptr with the content of oldp:- * If equal, the function atomically writes newv into ptr and returns true. * If they are not equal, the function atomically writes the content of ptr into oldp and returns false Since this is only for the x86 / x86_64 architecture, there is no weak variant.
