Of course - that's implicit in the sentence `A linker has detailed knowledge of the calling conventions and data types used by a
specific ABI` which appears quite early in the `Linker` javadoc. Also, the javadoc for `Linker::nativeLinker` states:


{@return a linker for the ABI associated with the underlying native platform}
