            Bug ID: 26112
           Summary: readelf --debug-dump=macro can't parse clang debug
                    info
           Product: binutils
           Version: 2.34
            Status: NEW

Clang binary output.

Test case:

$ echo "#define FOO bar" | clang -x c -c - -fdebug-macro -gdwarf-5 -o
clang-debug-macro.o
$ readelf --debug-dump=macro ./clang-debug-macro.o 
Contents of the .debug_macro section:

  Offset:                      0x0
  Version:                     5
  Offset size:                 4
  Offset into .debug_line:     0x0

 DW_MACRO_start_file - lineno: 0 filenum: 1
readelf: ./clang-debug-macro.o: Error:  Unknown macro opcode 0b seen



I'm using binutils-2.34.0-6.fc33 from Fedora and clang 11 (which is current
trunk).  It looks this used to work, but stopped working after clang commit:
