+// Test for the Triple constructor ambiguity fix on AIX
+// This test verifies that the default target triple is correctly resolved
+// and doesn't fall back to "unknown" due to constructor ambiguity.
+
+// REQUIRES: system-aix
+// RUN: %clang -v %s -c 2>&1 | FileCheck %s --check-prefix=CHECK-TARGET
