This reverts commit 723e0e2c1a.

Doug Coleman 723e0e2c1a vm: Allow larger 32bit code heaps. 
Code heap is artificially restricted on 32bit because PPC only had relative
jump instructions of a certain width and we punted on implementing
larger jumps.

Björn Lindqvist c8d648f3f2 VM: the factor_vm::code_blocks() method isn't needed 2016-04-22 12:01:26 +02:00
Björn Lindqvist 39c888230a VM: new function set_safepoint_guard to replace the functions (un)guard_safepoint 2015-08-24 07:23:40 -07:00
Björn Lindqvist 56ddb59b00 VM: new function set_memory_locked(true/false) 
it wraps the mprotect/VirtualProtect platform differences and makes it
so you can unify some windows/unix code path forks
 2015-08-24 07:23:40 -07:00
Björn Lindqvist 2b1c6ca11a VM: move the frame_predecessor() method to the code_heap class 2015-08-14 20:19:54 -07:00
Björn Lindqvist b44db91f65 VM: init_code_heap is trivial and only used once, so let's remove it 2015-08-04 16:02:08 +02:00

Björn Lindqvist 693e8ad33a VM: the clear_mark_bits methods are only called once -- make the calls inline instead 2015-01-15 09:29:14 +00:00
Björn Lindqvist fb9fa12cdd VM: change the definition of entry_point in word and quotation from void* to cell 
this gets rid of lots of redundant casts from void* to cell
 2015-01-15 09:29:13 +00:00
Björn Lindqvist 1beac119d8 VM: removes the template parameter from mark_bits 
since mark_bits only deals with arithmetic on memory addresses, it
doesn't need to be specialized so it can be untemplateized
 2015-01-15 09:29:13 +00:00
Björn Lindqvist 4a96e6163b VM: new primitive (callback-room) for querying the VM about memory usage 
The word works exactly like (code-room) except it looks at the memory
usage in the callback heap instead of the code heap.

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).
 2013-05-13 14:59:24 -04:00
Erik Charlebois 88d7c10d03 VM: Replace u8-64, s8-64, cell, fixnum with stdint.h equivalents 2013-05-13 00:28:25 -04:00
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.

Doug Coleman 2b33dde782 vm: Add more Allocates memory comments. 2013-03-25 17:52:30 -07:00
Doug Coleman 000efd9bbb vm: Add messages about things that can allocate. Fix a gc bug in the primitive for quotation-code. 2012-08-15 21:30:55 -07:00
Joe Groff 842eb27785 vm: cleanups 2011-12-14 09:56:50 -08:00
Joe Groff 2f20ee6fb0 vm: fix types after rebase 2011-12-14 09:56:49 -08:00
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 3868895b56 vm: make all_blocks a set of cells 
gcc was doing bad things assuming the pointer given to upper_bound was aligned
 2011-12-14 09:56:46 -08:00
Joe Groff 36d1e0a78c vm: verifier shouldn't check for leftovers 
It doesn't work after things have been freed
 2011-12-14 09:56:45 -08:00
Joe Groff e21f316583 vm: store stack frame size in code blocks 
Change modify-code-heap primitive so it takes a sixth element in each array for the frame size.
 2011-12-14 09:56:45 -08:00
Joe Groff bd7e6b33f8 vm: erase code blocks from all_blocks during sweep 
Fixes #437
 2011-12-13 12:28:09 -08:00
Joe Groff 083b856604 vm: reinitialize all_blocks from scratch after gc 
Faster and more likely to be correct than trying to fixup the existing set
 2011-12-12 19:05:48 -08:00
Joe Groff 4bbb2f5b72 vm: only verify all_blocks set if it's invalid 
Verifying on every sample is way too slow to be practical when debugging bootstrap.
 2011-12-12 19:04:56 -08:00
Joe Groff 15c4b7aa57 vm: verify code heap's all_blocks set when DEBUG 2011-11-23 11:11:27 -08:00
Joe Groff 0a1a252cdb vm: replace assert with FACTOR_ASSERT 
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.
 2011-11-23 11:11:26 -08:00
Joe Groff 81911b9f87 vm: initialize all_blocks map from image 
um, code blocks from the image need to go in the set too
 2011-11-23 11:11:26 -08:00
Joe Groff 2705fc67cb vm: keep a set of all code_blocks in the code_heap 
This way looking up code blocks by return address is an O(log n) set lookup rather than an O(n) linear scan.
 2011-11-23 11:11:26 -08:00
Joe Groff c31530caec vm: strip out call-counting profiler 
This makes the separate "code" and "entry_point" fields in word and quotation redundant, so also remove them to reclaim an additional cell per word and quotation object, which should help with #318.

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.
 2011-10-27 21:14:50 -07:00
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 4c8dec1e98 vm: take a page from code_heap for safepoints 2011-10-27 21:14:44 -07:00
