> @andrew.w.kaylor What is happening with this patch, will you be able to commit it for Jan 3 to fix PR35240? What about the high 8-bit register issue - is there a bugzilla (and repro) for this?


Yes. I apologize. I've had some other priorities that pushed this to the back burner, but I should be able to commit it today assuming a clean merge with the latest code base. I have not investigated the high 8-it issue, but I believe Andrei's example will demonstrate a problem. I think it is very unlikely to occur during actual compilation.
