Oh! I see. this is good news. Although that internals documentation is 
complete black magic to me and I cannot tell heads from tails in it, the 
surrounding comments sound promising... like GCC-13 actually had the 
internal "machinery" supporting named address spaces and just 
cpu-platform specific code is missing (for all but "SPU port"). Is that 
right?

And if it's so ... there is no mention of how does it show up for 
"simple user" of the GCC (instead of the use of that "machinery" by 
creators of particular GCC port). In other words: how the sources should 
look like for the compiler to do "the thing"?
