Does gdb actually support sh4 now? As far as I know, it currently doesn't.

See: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=576242

I'm one of the porters of the sh4 architecture for Debian and would be very
interested to finally have a working gdb on sh4.

Hi Adrian,

Thanks for your comment.  Based on the Debian bug that you linked, I think this
is a matter of reviving the patch that was sent to the gdb-patches mailing
list:

  <https://sourceware.org/ml/gdb-patches/2011-11/msg00490.html>

You might also be interested in pinging the original author of the patch.

Yeah, I guess. I definitely want to help to get this merged into gdb and I
would be happy to provide SSH access to a sh4 machine to anyone from the gdb
developers interested in reviewing the patch.

However, I am still waiting for my very own sh4 machine to arrive, it's
currently in the mail from Japan and that might take another month or so.

Once I have set everything up and working, I will ping back on the gdb mailing
list and ask for another attempt. I have also a very competent gcc expert at
hand who could help me reviewing the code.

Good idea, that's where I am going to start.

Adrian
