+# This test checks whether presence of debug declarations influences
+# the code generator or not. 
+#
+# If input.bc includes llvm.dbg intrinsics and llvm.dbg variables then
+# the code in first.s and second.s should match. Otherwise debugging information
+# is influencing the code generator.  The Dwarf info in first.s and second.s is
+# normally quite different, so the data directives that appear in Dwarf are
+# stripped out before comparison.
+#
+# This has only been used on Darwin; the data directives to strip and grep magic
+# might be different elsewhere.
