 No worries, and thanks for chiming in.  I plan to get one of my Alphas 
set up and wired in my remote lab later this year, so I hope to get a bit 
more active with the port.  At least I've got a reasonably recent build of 
the toolchain:

$ alpha-linux-gnu-gcc --version
alpha-linux-gnu-gcc (GCC) 12.0.1 20220129 (experimental)

 Umm, right, I came across them recently!  I'll see what I can do, however 
I don't have my SWARM in my remote lab, so I can only verify things when 
I'm next to it (which has been occasional only since the start of the 
bloody pandemic).  As I recall there was an issue with the incompatibility 
of the SMBUS protocol subset implemented by the SOC and the RTC causing a 
race.  I've had more stuff outstanding, such as PHY IRQ support for the 
Ethernet interfaces.

 And I yet have to see why my compiler miscompiled one endianness of CFE 
too (and find a way to publish my CFE fixes)!
