Hi Joern,
I have a patch for it, but due to problems with our hardware, newlib, andissues with the way the linux libgcc is built, I have not been able to test thepatch satisfactorily.
I can confirm that the patch allows GCC to build for both an sh64-elf and an sh-elf target. I am now running regressions tests to see if it introduces any new problems. (I doubt that it will, but it never hurts to check).
Cheers Nick
