[Ada] Crash on interface equality covered by a renaming declaration
The frontend crashes processing a tagged type that implements an interface which has an equality primitive (that is, "=") and covers such primitive by means of a renaming declaration. 2018-11-14 Javier Miranda <miranda@adacore.com> gcc/ada/ * exp_disp.adb (Expand_Interface_Thunk): Extend handling of renamings of the predefined equality primitive. (Make_Secondary_DT): When calling Expand_Interface_Thunk() pass it the primitive, instead of its Ultimate_Alias; required to allow the called routine to identify renamings of the predefined equality operation. gcc/testsuite/ * gnat.dg/equal5.adb, gnat.dg/equal5.ads: New testcase.
