Joe Groff 1351e30e52 vm: sampling profiler timer for windows
Spawn a thread and have it spin on the performance counter, triggering safepoints on the main thread every sample time
2011-11-02 13:23:11 -07:00
Joe Groff f5cdfaeb2a vm: count samples from foreign threads
On OS X it appears the mach exception thread and libdispatch queue threads occasionally get the SIGALRM from the itimer. Count those as foreign_thread_samples instead of letting the signal kill the process.

Joe Groff be5c7476d7 vm: don't allocate callstack samples on data heap
Invoking a GC during a safepoint has some complications, so stuff the callstack samples in a vector instead.
2011-11-02 13:23:07 -07:00
Joe Groff 80fb7788d9 vm: groundwork for sampling profiler
Set up the state necessary to collect samples. We still need to add GC support for walking the sample set, and the compiler needs to register GC roots before safepoints as well. We also need primitives to expose the data to Factor for reporting.

Joe Groff 5d59faa7d1 vm: move dispatch_signal_handler to cpu-x86.cpp

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.
