Re[2]: [9fans] Plan9 16bit C compilers

[steve.simon]

Hi,

For what its worth, I wanted to use Plan9 as my developement enviroment -
porting
the compiler rather than the whole OS.

We have jokeingly talked about a full plan9 port but I assume that is a
non-starter for such a basic CPU -
No memory management, not even 8086 style segementation registers, and no memory
protection.
So we would have to use link on load or get the compiler to produce position
indepandant code (not easy
on this CPU)... or I suspose we could have a CP/M style TPA :-(

Delving into history this is (I think) what was done with MiniUnix (A cut down
Version 7) in the early 1980s at the labs (again not sure, its a long time since
I read the paper). That ran
on an LSI 11/23 and I did notice that the source is available... no that would
be silly...

I was just wanted to know if there was a fundamental problem with building the
Plan9 compiler for
16bit (IE All registers 16 bit, no FPU, 16Mbyte flat address space etc)?
