The result of BLISS was VAX assembler code rather than raw machine code, which is why the port to Alpha went the way it did. Bliss fell out of favour at DEC becuase it required programmers to learn a new style of coding from C so the Alpha code used more C than Bliss.
Actually, no. The "Digital Technical Journal" ran an article at the time titled "Porting OpenVMS from VAX to Alpha AXP": Most of the OpenVMS kernel is in VAX assembly language (VAX MACRO- 32). Instead of rewriting the VAX MACRO-32 code in another language, we developed a compiler. In addition, we required inspection and manual modification of the VAX MACRO-32 code to deal with certain VAX architectural dependencies. Parts of the kernel that depended heavily on the VAX architecture were rewritten, but this was a small percentage of the total volume of VAX MACRO-32 source code. http://research.compaq.com/wrl/DECarchives/DTJ/DTJ800/ It's pretty clear from the details given in that article that very, very little of VMS (the OS) was in BLISS at the time of the Alpha port. This counterexample refutes your argument. I'm truly sorry: it's such a seductive theory, like the "market share" argument for Windows viruses and worms. _______________________________________________ Full-Disclosure - We believe in it.
