Elf2flt with PIC, ZFLAT and full reloc support. Currently supported
|
||
|
|
targets include: m68k/ColdFire, ARM, Sparc, NEC v850, MicroBlaze,
|
||
|
|
h8300, SuperH, and Blackfin.

COMPILING:
|
||
|
|
|
||
|
|
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
|
||
|
|
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.

FILES:
|
||
|
|
|

|
|
README - this file
|
||
|
|
configure - autoconf configuration shell script
|
||
|
|
configure.in- original autoconf file
|
||
|
|
config.* - autoconf support scripts
|
||
|
|
Makefile.in - Makefile template used by configure
|
||
|
|
elf2flt.c - the source
|
||
|
|
flthdr.c - flat header manipulation program
|
||
|
|
flat.h - header from uClinux kernel sources
|
||
|
|
elf2flt.ld - an example linker script that works for C/C++ and uClinux
|
||
|
|
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
|
||
|
|
linking.
|
||
|
|
|
||
|
|
TIPS:
|
||
|
|
|
||
|
|
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).
