Joe Groff 23208e5697 vm: give factorbug a help command
Also change the prompt to "> _" instead of "READY\n_" since it's not 1970 anymore

Joe Groff af0f021a94 vm: change factorbug "q" to quit process
Also change the docs around so the useful commands are all listed under "Basic commands", and rename the more arcane "s" and "r" dumps to "ds" and "dr".

Joe Groff b0b0905460 vm: add factorbug command to throw exception
Also rename "q" to "c" because it "c"ontinues, remove the useless "im" command, and rename the less useful "t" to "trim" so we can use "t" to mean "throw"

Joe Groff dc42365007 vm: fep on SIGINT or SIGQUIT instead of exception
It's not robust currently to raise an exception because a lot of our code that isn't already written with exceptions in mind breaks. Also, a signal is likely to be received by an FFI callback installed on the IO multiplexer, which will cause Factor to die since the callback cannot handle the exception. We need a more robust solution to dealing with SIGINT.

Also lay some groundwork for counting profile samples and reporting non-interrupting asynchronous signals.

Slava Pestov 45eb68fa38 vm: during tenuring stage of aging collection, if tenured space fills up, it would attempt a to_tenured collection. this will succeed if all roots were tenured. however, this is unsound, because there's now an untraced segment of tenured space. fix: if tenuring fails, go on to do a full collection instead 2009-10-15 05:51:11 -05:00

Slava Pestov c4ef640f4d Big VM cleanup
- Move forward declarations of 'struct factor_vm' to one place
- Rename template parameters from T and TYPE to descriptive names. New convention: CamelCase for template parameters
- Change some higher-order functions taking function pointers into templates, and define classes overriding operator(). There's a bit of new boilerplate here but its more consistent than the old mish-mash approaches
- Put GC state into a gc_state struct
- Use exceptions instead of longjmp for non-local control transfer in GC
- In code GC, instead of interleaving code block tracing with copying, add code blocks which need to be revisited to an std::set stored in the gc_state
