compiler.*: removing the check-d and check-r slots from gc-map and adjusting code that depended on those
2015-04-29 09:31:53 -07:00

VM: the compiler doesn't emit any live overinitialized locations anymore
...
Any overinitialized location immediately becomes garbage and is not
reused again. This is very nice because then the gc maps can be
simpler again.

VM: simplification of the trace_partial_objects function

VM: the unmarker classes are not needed, easier to just send the unmask pattern to the trace_cards function directly
2015-02-28 14:14:30 -08:00
b5a206c587
VM: new function visit_mark_stack() to factor out the mark stack iteration

VM: it's confusing that slot_visitors are called "workhorse" sometimes, let's standardize the name "visitor"
2015-02-28 14:14:29 -08:00
5490c50217
VM: visit_roots and visit_contexts where always called in tandem, make a new method visit_all_roots that calls them both

VM: possible fix for #1265 . the size of the stack frame appears to have been miscalculated in iterate_callstack which this commit fixes.

ee5fd49b9e
VM: simplified fixup_gc_workhorse::fixup_data by mering lots of functions only used once
2015-01-15 09:29:14 +00:00
8ea1eea4e1
VM: instead of passing around the trace_contexts_p arg, just clear the contexts in primitive_save_image_and_exit() it has the same effect but is simpler
2015-01-15 09:29:14 +00:00
4d7bc4c169
VM: merge of slot_visitor and code_block_visitor
...
Looks like there is no reason for them to be separate classes and by
merging them you can simplify lots of code.
2015-01-15 09:29:14 +00:00
d2aea0f606
VM: replaced the reset_generation() generic method with one method for each generation
2015-01-15 09:29:14 +00:00
dc9e937beb
VM: vm::iterate_active_callstacks is only used once, so it's simpler if the code body is "inline"
2015-01-15 09:29:14 +00:00
b61eaa8a16
VM: the full_collector class isn't needed since it is only used once
2015-01-15 09:29:14 +00:00

VM: the clear_mark_bits methods are only called once -- make the calls inline instead

VM: change the definition of entry_point in word and quotation from void* to cell

f0bf693beb
VM: free_list_allocator::first_block, last_block and next_block_after can be refactored away
2015-01-15 09:29:13 +00:00
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
af270cb4d8
VM converts the methods callstack::frame_top_at and code_block::offset to use cells instead of void*'s
2015-01-15 09:29:13 +00:00

VM: calls to visit_code_roots() replaced with visit_uninitialized_code_blocks()

VM: some more fixing to make the types match better, converting void* to cell
2015-01-15 09:29:13 +00:00
e47181e87a
VM: change type of callstack_top and callstack_bottom from void* to cell
...
cell and void* is always the same size, but now you can remove lots of
redundant type casts from void* to cell.
2015-01-15 09:29:13 +00:00
a6e191a490
VM: the frame_return_address and set_frame_return_address functions aren't needed (clearer to read/write the pointers directly)
2015-01-15 09:29:13 +00:00
11e906139b
VM: code_block::scan, make it so the method always returns -1 if scan can't be determined, part of the fix for #1265
2015-01-15 09:29:13 +00:00
8ee1f890f2

VM: modifying the uninitialized_blocks map in place instead of creating a new one is more efficient

VM: the aging_collector and nursery_collector classes aren't needed because they are just simple instatiations of copying_collector

Code formatting fix.

VM: move next_object_after() and first_object() to aging_space (no iteration possible in nursery)
2014-11-21 02:16:04 -08:00
50c74fc496
VM: get rid of the duplicated nursery instance in vm->data->nursery
...
vm.nursery and vm->data->nursery are different objects. They get out
of sync when Factor code bumps vm.nursery but leaves vm->data->nursery
unchanged. The emptiness of vm->data->nursery meant that each_object()
never iterated it.
2014-11-21 02:16:03 -08:00

VM: each_object() can't iterate the nursery so instead we assume it's empty
