Has anyone attempted a GNU C machine description for a DEC KL-10/20? Does anyone have any thoughts on the do-ability of such a thing? Thanks for all feedback.

I would say it's doable. Many many moons ago a fella named Don Wakelin at ADP Network Services successfully brought up a C compiler on a PDP-10. The issues of 'what is a character' were a lot of fun, but the end result was a runnable C compiler which they used for some real products that ran on MS-DOS, UNIX, and TOPS-10. Both Don and I are long gone from ADPNS and I dunno where he went. If memory serves it took him months of part-time effort. As a starting base I think he used a C compiler for some 12-bit Harris machine, so a lot of the wierdness of char sizes had already been dealt with.

JTW@XX.LCS.MIT.EDU ported PCC to TOPS-20 some time ago. (Note: XX used to be running TOPS-20, but now seems to be running 4.3BSD, but I dont thing the reason is because they ported 4.3BSD to a DEC-20). Who knows, perhaps someone might port GCC to an ITS machine some day. -gjc
