Joe Groff ca0dfc5730 vm: get CtrlHandler working on windows 2011-10-27 21:18:21 -07:00
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 03ebb91170 vm: remove signal_from_leaf flag
Now that the resuming from the signal handler works within leaf procedures, the flag is no longer necessary.

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 7c3827190b Tease out symbol name and library in undefined_symbol() handler, for friendlier errors when calling an unresolved C function name. Fixes #93 2011-09-12 00:56:24 -07:00

Slava Pestov f27080498d Remove bignum>float VM primitive, and use bignum/f to implement >float on bignums instead, for a slight accuracy gain. Also, bignum/f now has a more efficient post-scaling algorithm to break the circular dependency on bignum>float 2010-11-24 22:41:15 -08:00

Slava Pestov e8b1a06dad vm: a stack underflow inside a primitive could leave a data root in an uninitialized state; if allocating the thrown underflow error triggered a GC, the GC would visit a garbage pointer 2010-09-17 19:46:57 -07:00

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
