Joe Groff 6d57eb4f59 vm: update windows for resumable signals 2011-10-27 21:18:21 -07:00
Joe Groff 5d59faa7d1 vm: move dispatch_signal_handler to cpu-x86.cpp
The new signal handler dispatch is logic is CISC-centric; defer fixing it until we find someone who cares

Joe Groff dca0fd3487 vm: Revert extra canary page before callstack
This reverts commit 7d5c8d6990385b94569116a23163d7e75ae21f49. We pretty much can't avoid unwinding frames without some more drastic redesign.

Joe Groff c3f007ce0a vm: allocate an extra canary page before callstack
This will let us safely unguard the callstack overflow guard page as a grace page so the callstack overflow handler can do its business without discarding frames.

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.

Joe Groff 1dc31d133b vm: clean up signal handler dispatch
Remove the weird and broken functions fix_callstack_top and scrub_return_address. Instead, simply decrement the SP and store the PC from the front end of the signal handler so that the back end can return back into the original context normally. Currently aborts for leaf procedure frames pending a more robust solution.

Slava Pestov 1818bcb780 Fix three problems discovered by running math.floats.env tests in a loop:
- Crash if allocating error triggers a GC from a signal/SEH handler
- Crash if GC runs with floating point traps enabled on Windows
- Floating point traps didn't prettyprint properly
