Hi, we've put together a Linux/ARM cross compiler tool kit.  The
kit includes the latest version of GNU GCC with Linux/ARM patches,
binary utilities for ARM ELF, and pre-built libraries for linking
ARM ELF binaries.

Please download the following files from the SimpleScalar/ARM release
directory (http://www.eecs.umich.edu/~taustin/simplescalar):

  binutils-2.10.tar.gz
  gcc-2.95.2.tar.gz
  glibc-2.1.3-armlinux.tar.gz

And get the latest version of SimpleScalar/ARM, we made a few fixes
since the last experimental release, some are needed to run cross
compiled binaries:

  simplesim-arm-0.2.tar.gz

You'll have to use the user login and password that I sent
previously.

You should be able to build these tools on most any Unix platform,
and use them to generate binaries in ARM ELF format, suitable for
running on SimpleScalar/ARM simulators.  This release needs your
testing, we've built a few benchmarks with no problems, all our
tests were on Linux/x86 boxes.  If you have any problems, please
e-mail simplescalar@yahoo.com.

Best Regards, -Todd Austin


--------------------------------------------------------------------

Building arm-linux cross compilers:

1) make a directory to house the cross compilers, let's call it <CROSSDIR>

2) cd <CROSSDIR>

3) unpack the binutils, gcc, and glibc tarballs that you downloaded

4) build the binutils:

   cd binutils-2.10
   ./configure --target=arm-linux --prefix=<CROSSDIR>
   make
   make install
   cd ..

5) add <CROSSDIR>/bin to your executable path, do a "rehash" so you can see
   the new executables

6) build GNU GCC:

   cd gcc-2.95.2
   ./configure --target=arm-linux --prefix=<CROSSDIR>
   make LANGUAGES=c
   make LANGUAGES=c install
   cd ..

7) vi lib/gcc-lib/arm-linux/2.95.2/specs

   replace all occurrences of "elf32arm" with "armelf_linux",
   this fixes an innocuous incompatibility between the most
   recent GCC and GLIBC libraries...

8) finally, do a "rehash" to see the rest of the new executables on your
   search path

To cross compile a binary that can be run on SimpleScalar/ARM:

  arm-linux-gcc -o <binary> -O <sources...>

plus, all the other binutils are available for ARM ELF, e.g.,
arm-linux-objdump, arm-linux-nm, etc...
