I'm afraid it's wrong because from my point of view Clang generates wrong message for test OhNo3 (see err_typecheck_assign_const.cpp). It should not be "read-only variable is not assignable" because v[4] is not read-only variable. Any other non-const method is able to change this variable w/o any problems. The the same is for OhNo and OhNo2. BTW, gcc generates error: assignment of read-only location ‘*(const float*)(&((const OhNo2*)this)->OhNo2::v)’ and that's OK because we try to change the value through const-pointer-to-const. Am I right? https://reviews.llvm.org/D42530 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
