rsmith added a comment. So the driver would pass a flag to the frontend to indicate "this target probably doesn't have aligned allocation support", and Sema would produce a warning if it selects an aligned allocation function when that flag is specified? That makes sense to me.
Should we also remove the recently-added availability attributes in libc++ too? If I'm using a recent libc++ and providing my own aligned allocation functions, we shouldn't reject attempts to call those aligned allocation functions. https://reviews.llvm.org/D34574 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
