VP assembly code demo for the skeptics : Comment 12 of 14ANN.lu

This from the previous article:
----------------------------------------------------------------------------
dW: Does the included GNU C compiler compile into VP code?
Moss: It's a two-stage process: The C compiler actually compiles into VP source code that is then assembled into VP object code. One of the differences of coding in C as opposed to VP is that you're at the mercy of how it translates C into VP [which means the C compiler produces one big tool, similar to a traditional monolithic executable, so your code isn't composed of many tiny lightweight tools like the rest of the system.] Doom was ported from the open, available C sources in 15 minutes, and I think Quake took about an hour or two hours. It has full ANSI-C compliance. The people who have used VP so far have said that they really like it, but sometimes they get a bit confused because things seem C-like and Linux-like, and yet they're not. So there's a bit of a learning curve to it, but it's not much -- these people are all over it. Because initially we saw everyone say, "We're only using C," and a lot of them said, "No way, we're not coding in assembler," and then they see it and fall in love. And they're actually using VP more.

Well I think I'm one of those "No way! I'm not coding in ASM" people! :)
