there was a native plan9 dis interpreter that would run simple command line applications. on Andrey’s website i think.

That's a brilliant idea: a "Dis" assembler for Plan 9, to compile (well, assemble, really) Dis code to binaries for the host architecture. The Dis architecture was specifically designed to make it easy to map the Dis machine to the underlying architecture. But... the binary interface would have to be the Plan 9 one, so the proper place to do such assembly would be on Plan 9. If it were an extension of Inferno's JIT, it would have to track changes made to Plan 9. Since Dis is stable and standardized, it makes more sense for a Plan 9 tool to track Dis than the other way around. Come to think of it, you wouldn't even need to implement a full assembler. Assembling Dis on Plan 9 could be achieved simply by dis-assembling (a la appl/cmd/disdump.b) Dis modules to Plan 9 assembly language. The Plan 9 assembler suite already exists. ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T39aec8f3f9d8503d-Mf9a948381985f924fa04f466 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
