binutils for TI Cxx

binutils for TI Cxx

[Joel Sherrill]

Does anyone know the status of the binutils support for the
TI C3x and C4x in either 2.9.1 or the development snapshots?

http://www.elec.canterbury.ac.nz/c4x/ is still listing patches
against 2.7 as the stable version.

The development snapshots includes TI C3x support, using COFF or
a.out.  This was contributed by Steve Haworth.  I don't think I have
patches for TI C4x.  I don't know how different the chips are.

I don't think there is any gcc support for either chip in the main
tree.

I think they are similar although like all CPU variants, instructions
always differ. :)

I guess I can email Steve and see how this relates to the patch on
the gcc_c40 web site.

Thanks.

Actually the c4x is merged although according to the web site
of Michael Hayes who did the port, it does not include "aggressive
optimizations".  He distributes a patch for that part.

I need to check on the gdb support also.  There is a cycle accurate
simulator
for this CPU.
