            Bug ID: 39841
           Summary: Support ihex format
           Product: tools
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement

Some users of objcopy (I think mostly embedded) rely on the ihex [1] format in
their toolchains.

e.g.
generating ihex: clang -o foo foo.o && llvm-objcopy -O ihex foo foo.hex
converting to binary: llvm-objcopy -I ihex -O binary foo.hex foo.bin

We already have {Binary,ELF}{Reader,Writer} classes, this would require a third
Ihex{Reader,Writer}.
