These would be questions that Lars Brinkhoff could answer best. The C compilier being used is his port of GCC to TOPS-20. The port of NetBSD was advanced to the above point in a matter of weeks by Anders Magnusson. He and Lars have been working closely together to iron out some things with the compiler. I'm not sure precisely what decisions were made; updates on the project have been rather sparse. When they do come, they've been significant; but it's been a since I've heard anything. I believe Anders has been preoccupied with his real-life job.

The > C compilier being used is his port of GCC to TOPS-20. Size, in bits, of various C types: char 9 short 18 int 36 long 36 long long 72 (not double-precision integer format) float 36 (single-precision format) double 72 (double- or giant-precision format) all pointers 36 (word address or byte pointer) There is also support for 6-, 7-, and 8-bit bytes as supported by one-word global byte pointers. Support for 16- and 32-bit integers is currently weak. > it's been a since I've heard anything [about the NetBSD port]. I > believe Anders has been preoccupied with his real-life job. Maybe, but it's also the case that we've ran into a compiler bug which we don't quite know how to fix. Anders doesn't quite have the GCC expertise, and I'm somewhat busy with work and other things. -- Lars Brinkhoff http://lars.nocrew.org/ Linux, GCC, PDP-10, Brinkhoff Consulting http://www.brinkhoff.se/ HTTP programming
