But there were ideas! But not only the interesting ideas (like the

It's been a while since I coded up raw SPARC ASM. Remember that
branch delay slot? Ever use it with a MEMBAR instruction? Shit
would hit the fan. 

 
As mentioned somewhere upthread I haven't ever programmed a SPARC on
assembler level, just studied some documents. I'm not even sure the
term "frame shift on the stack" that I used is accurate or correct;
it's just an informal description of a technical detail that I had
considered to be interesting. (Instead of copying parameters/results
with function calls between callers and callee you could just shift
a "stack window" by adjusting a register (or so).
 
So, no, I cannot remember a "branch delay slot". - Sorry. - Want to
elaborate on the story?

You didn't ever programmed in SPARC asm. Your reading of SPARC
documents was so shallow that you didn't pay attention to highly
visible distinguishing feature as branch delay slot.
Could I guess that you didn't ever programmed in 68K asm, x86 asm,
NS32k asm, MIPS asm etc... ? Could I guess that your reading of
respective ISA docs was also similarly shallow? Could I guess that the
only non-8-bitters that you ever programmed in asm were one or couple
of TMS3202x DSPs?
