Abstract: An illustrative embodiment of a computer-implemented process for an enhanced function-descriptor-based dispatch in a multi-linkage environment receives user code containing a function compiled in a supplementary linkage convention of a caller to form an invoked function and determines whether the supplementary linkage convention of the caller for the invoked function matches a supplementary linkage implementation provided by a library. Responsive to a determination that the supplementary linkage convention of the caller for the invoked function matches a supplementary linkage implementation provided by the library, select the supplementary linkage implementation provided by the library and dispatch the invoked function in the selected supplementary linkage implementation provided by the library.
