DWARF is a file format for representing debugging information.

The DWARF format is used to represent information needed for source-level debugging of programs.

The DWARF format is designed to be processor architecture and operating system independent, and supports debugging of programs written in procedural languages like C, C++, FORTRAN, Ada, Java, Modula2 and Pascal.

DWARF is widely used in modern proprietary and open-source operating systems, for example, Linux, Android, BlackBerry OS 10 and others.

How can I convert from DWARF version4 to version2 ? ( without recompiling )

I'm trying to debug a program that uses DWARF-4 but my gdb is too old and only understands DWARF-2. I can't update gdb and I can't recompile, so I need a way to convert them, maybe with some binutils tool?
