And which language and compiler case was this aimed at?  

Wasn't that a primary driver for complex CISC instructions?  That if it 
happened often enough, it would be faster or smaller as a single instruction?

I dunno, 68000 seemed like PDP-11 to me, and I often say one of the big reasons
I quit a particular job was the prospect of my role changing to having to write
80x86 assembler all day.

And yes I quit that job to become an Amiga magazine writer.  :-)
