+# This tests that a static member in a class declared in the anonymous namespace
+# does not appear as a field of the class. There is a difference between the
+# debug info generated by gcc and clang, where clang flags the static member
+# with DW_AT_external, but gcc does not.
+#
+# This is the code used to generate the assembly:
+#
+# namespace {
+# struct U {
+# static const int s = 0;
+# int m;
+# };
+# }
+#
+# U constant;
+#
+# int main() {
+# return constant.m;
+# }

+# Compiled with:
+# gcc -S -g test.cpp
