Bug ID: 83083 Summary: c++2a concepts without -fconcepts Product: gcc Version: 8.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: h2+bugs at fsfe dot org Target Milestone: --- Currently GCC offers the Concepts TS via -fconcepts, but it doesn't seem to offer the modified/reduced Concepts merged into C++2a. For forward compatibility checks of existing code and also for comparison with other compilers (which will hopefully start supporting C++2a concepts sometime next year), it would very, very helpful if GCC8 provided the new concepts-light-light via the regular -std=c++2a switch (without -fconcepts). Is this a planned feature or not a priority? Will it make it into GCC8? I know these things are not trivial, but it seems like it's "only" a subset of already existing features that "just" needs to be rewired. Thanks a lot for your work on this!
