+    testsuite: fix dwarf2/utf-1.C with DWARF4
+    
+    Running
+    $ make check-c++ RUNTESTFLAGS='--target_board=unix\{-gdwarf-5,-gdwarf-4\} dwarf2.exp=utf-1.C'
+    shows
+    FAIL: g++.dg/debug/dwarf2/utf-1.C  -std=gnu++20  scan-assembler-times DW_AT_encoding \\(0x10\\) 3
+    because with -gdwarf-4 the output is:
+    
+      .byte   0x10    # DW_AT_encoding
+    
+    but with -gdwarf-5 the output is the expected:
+    
+                    # DW_AT_encoding (0x10)
+    
+    The difference is caused by the DWARF5 optimize_implicit_const
+    optimization:
+    <https://gcc.gnu.org/pipermail/gcc-patches/2016-October/459762.html>
+    
+    I suppose we could do what testsuite/rust/debug/chartype.rs does
+    and just run the test with -gdwarf-4.
+    
+    gcc/testsuite/ChangeLog:
+    
+            * g++.dg/debug/dwarf2/utf-1.C: Use -gdwarf-4.  Adjust expected
+            output.
