This directory contains the specifications for SYCL extensions that are proposed for the DPC++ compiler. These extensions are not implemented in DPC++, so they cannot be used. These extension documents are published here to gather community feedback.
A proposed extension may eventually be implemented, thus promoting it to "supported" or "experimental". When this happens, the specification document is generally moved to either the "supported" or "experimental" directory, and there may also be some changes to its APIs.
