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.
