Unobtanium mistake no.1 :Poor Assembly language design
it's an black box (proprietary design) only for compiler "elite",
One day or another you have too see the assembly source code,
Real man do know assembly language ,even if they don't program
in it .
"IA64 assembly was never meant to be written by a human. It is a processor design driven by compiler research."
If you don't believe me , read intella's itanic manuals
