Elf2flt with PIC, ZFLAT and full reloc support. Currently supported
targets include: m68k/ColdFire, ARM, Sparc, NEC v850, MicroBlaze,
h8300 and SuperH.
You need an appropriate libbfd.a and libiberty.a for your target to
build this tool. They are normally part of the binutils package.
To compile elf2flt do:
./configure --target=<ARCH> --with-libbfd=<libbfd.a> --with-libiberty=<libiberty.a>
make install
The <ARCH> argument to configure specifies what the target architecture is.
This should be the same target as you used to build the binutils and gcc
cross development tools. The --with-libbfd and --with-libiberty arguments
specify where the libbfd.a and libiberty.a library files are to use.

ld-elf2flt - A linker replacement that implements a -elf2flt option for the
linker and runs elf2flt automatically for you. It auto
detects PIC/non-PIC code and adjusts its option accordingly.
It uses the environment variable FLTFLAGS when running
elf2flt. It runs /.../m68k-elf-ld.real to do the actual
The ld-elf2flt produces 2 files as output. The binary flat file X, and
X.gdb which is used for debugging and PIC purposes.
The '-p' option requires an elf executable linked at address 0. The
elf2flt.ld provided will generate the correct format binary when linked
with the real linker with *no* '-r' option for the linker.
The '-r' flag can be added to PIC builds to get contiguous code/data. This
is good for loading application symbols into gdb (add-symbol-file XXX.gdb).
