Hi Larry, Note that you can no longer get to me on [email protected]. (McAfee shutdown the Snapgear group a couple of years back, and I am no longer with them. Unfortunately the email address doesn't bounce :-( Using [email protected] is best.

I posted an announcement here as well back on 25 September 2012. The recent conversations here about ColdFire processors made me think someone might still care about that work. > > Merging my patches into the gcc trunk keeps getting deferred. The last time I had any correspondence with anyone about a time frame, I think the delay was because of the lack of someone working on the m68k code in the compiler. I've never written any compiler code before this, but I do know how to read assembly language to see what the compiler is emitting. (That's how I determined the existing implementation was not right and not as efficient as it could be.) I was able to generate and run my code on uClinux with the stack checking option using my patched gcc. It is a shame this is taking so long to get back into gcc proper. But thanks for the good work, and posting it here.
