Doug Coleman 1ad2e058d1 alien.cpp: Add comment about allocation. 2013-11-28 10:59:45 -06:00
Doug Coleman 268fa0225d os-windows: Remove FACTOR_DLL which is NULL and only used in one place. 2013-11-24 22:06:57 -06:00
Doug Coleman 0a5cdfa3e6 vm: init_parameters_from_args calls default_parameters already. 2013-11-24 22:06:57 -06:00
Erik Charlebois 40fcee3f16 VM: Fix Windows 64-bit build on Visual Studio 2012
The UNW_FLAG_EHANDLER #define is now visible in VS2012, causing
a conflict with the definition in os-windows-x86.64.cpp. Added
a #ifndef to only include the definition if it hasn't already
been defined.

Erik Charlebois 5027f75d79 VM: Fix Windows VM build following type renaming
Making cell be a typedef of uintptr_t broke a spot assigning
cell* was unsigned long*. Added an explicit cast.
2013-05-13 18:18:48 -04:00
Erik Charlebois ffe41b3d7f VM: Fixup cast formatting after clang-format
clang-format doesn't recognize casts to non-pointer/non-template types
so it winds up adding a space between the right paren and the expression
and then failing to recognize prefix operators in the process
(e.g. foo = (cell) & bar; should be foo = (cell)&bar;). This commit
manually fixes up the major cases (fixnum, cell, all types ending in _t).

Erik Charlebois b918c3e646 VM: Remove redundant #ifdef FACTOR_DEBUGs
FACTOR_DEBUG checks around asserts aren't needed, since FACTOR_ASSERT is
already conditionally defined by FACTOR_DEBUG.

Joe Groff 9236c05e60 vm: stage code block map fixup properly for GC
Don't update the map until the very last thing, and pass untranslated addresses to the iterator functors. Somewhat complicated by the fact that, for startup_fixup, the map is initialized with fixed-up values, so the fixup functor needs a flag indicating whether it operates with a fixed or unfixed code heap map.

Joe Groff ef38688e87 vm: method to calculate frame size for address
If we're before the prolog or or in a leaf procedure, the stack frame is really a leaf frame created by the signal handler, with a known fixed size, instead of the real stack frame (if any) with a different size.

Factor is finally a real C++ project and has a custom assert macro. Assertion failures were still getting caught as exceptions and causing failure loops. Write our own macro that calls factor::abort on failure.

Joe Groff e0dc236725 cpu.*.bootstrap: clear faulting flag directly
No reason to go through a safepoint in unwind-native-frames really.
2011-11-12 13:02:57 -08:00
Joe Groff e24400679f vm: more defense against multi-faulting
* Clear faulting_p from a safepoint rather than inside general_error, because jumping into unwind-native-frames could blow up.
* Handle multiple faults from fatal_error by breakpointing. Is there anything else we can safely do at that point?
* Verify memory protection faults in the top half of the signal handlers because signal dispatch could fault. Treat memory faults during gc or fep as fatal errors.
* Add a function factor_vm::abort() that restores the default SIGABRT handler and ::abort()s. Use it from fatal_error() so we get useful context from gdb and so the user gets feedback from the system crash reporter that Factor blew up and didn't just disappear.
* In factorbug(), don't proceed with .s .r .c if it would be unsafe to do so.
* Don't pile on signals if we've already called fatal_error().

Joe Groff 139c9ca38c init signals or console after stage2 init
A signal during early bootstrap is certainly an error, and the environment isn't there yet for Factor's signal handlers to work, so it makes no sense to install Factor's signal handlers beforehand. They'll just crash.

Joe Groff 9e4a51c55f vm: don't SIGQUIT on unix or Ctrl-Break on windows
This gives us an escape hatch for when things go way south and ^C can't be handled. Also unmask SIGQUIT and SIGTERM from the stdin_loop thread so the thread doesn't keep the process alive after those signals.
