Slava Pestov 18e8c0af9c vm: don't keep more than 10 unused contexts around to prevent address space wastage on low-budget operating systems like OpenBSD 2010-09-17 20:52:27 -07:00
Slava Pestov 05fc6ddad6 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 09c74bda0b vm: don't call nano_count() from the GC at all, unless GC event recording is on 2010-09-04 13:21:45 -07:00
Slava Pestov 0797875ef5 vm: fix crash when doing GC with profiling enabled 2010-09-03 21:54:40 -05:00
Slava Pestov 55ac874eb2 vm: Remove signal_callstack_top nonsense 2010-09-02 22:57:17 -05:00
Slava Pestov 6617eca683 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

Slava Pestov 310399995e Add code heap introspection primitive to VM, and make a code-blocks word in tools.memory that wraps a useful interface around this. Add a lookup-return-address word and use this in tools.disassembler.utils 2010-02-03 23:11:32 +13:00
Slava Pestov d19709c188 vm: modify-code-heap primitive now takes a pair of parameters, update-existing? and reset-pics?. If no generic words were changed, PICs do not need to be reset. If no existing words were redefined, the code heap doesn't have to be traced at all. Speeds up compilation of PEGs since those create lots of compilation units 2010-02-03 23:11:28 +13:00
