+// The compiler used to not pay attention to package for non-exported
+// methods when statically constructing itabs. The consequence of this
+// was that the call to b.F1(b.T{}) in c.go would create an itab using
+// a.T.m instead of b.T.m.
+func F1(i interface{ m() }) { i.m() }
+
+// The interface method calling convention depends on interface method
+// sets being sorted in the same order across compilation units.  In
+// the test case below, at the call to b.F2(b.T{}) in c.go, the
+// interface method set is sorted as { a.m(); b.m() }.
+//
+// However, while compiling package b, its package path is set to "",
+// so the code produced for F2 uses { b.m(); a.m() } as the method set
+// order. So again, it ends up calling the wrong method.
+//
+// Also, this function is marked noinline because it's critical to the
+// test that the interface method call happen in this compilation
+// unit, and the itab construction happens in c.go.
