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 10845ebfb9 callstack.cpp: fix fat-fingered typo from undefined-symbol change 2011-09-12 23:15:09 -07:00
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 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 d74817cedf vm: Remove signal_callstack_top nonsense 2010-09-02 22:57:17 -05:00
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

- some other minor re-organizations and cleanups

Slava Pestov 697e2342d0 vm: put code block owner directly in the header, instead of as the first entry in the literal table. Reduces x86-64 image size by ~700kb, also eliminates separate 'strip' set of staging images from deploy tool 2009-10-06 06:25:07 -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
