Björn Lindqvist bf7161604e VM: simplified logic in data_heap_checker 2015-05-17 07:59:34 +02:00
Björn Lindqvist 3887b58c02 VM: cleanups, like removing redundant paranthesis and removing method 
declarations that doesn't exist
 2015-05-09 20:04:22 -07:00
Björn Lindqvist a6e2834252 VM: refactoring to use the visit_object_array method 2015-05-09 20:04:21 -07:00
Björn Lindqvist 0a6486ef78 VM: the aging_policy and nursery_policy classes are so small that they 
can be in the same cpp file with the methods that use them
 2015-05-09 20:04:21 -07:00
Björn Lindqvist e4bb3058e0 VM: the copying_collector only contained one method, so it can easily be 
merged with its base class
 2015-05-09 20:04:21 -07:00
Björn Lindqvist 685a795aa0 VM: to_tenured_collector isn't needed, it's just a normal collector instance 2015-05-09 20:04:21 -07:00
Björn Lindqvist 9bfc43144e VM: debug macros FACTOR_PRINT and FACTOR_PRINT_MARK to make better debug 
printing messages than just using std::cout
 2015-05-09 20:04:21 -07:00
Björn Lindqvist fa0ff77c45 VM: reset the unused parts of the data and retain stack segments with a bit pattern (good for debugging) 2015-04-29 09:31:54 -07:00
Björn Lindqvist acc1bd3221 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
Björn Lindqvist 2cd2aa498a 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.

Björn Lindqvist 1d251f7b6a VM: new function visit_object to replace trace_object 2015-02-28 14:14:30 -08:00

Björn Lindqvist 0798928996 VM: cleanup of some infrequently used functions that can be replaced with direct code 
also replacing some bitshifts with easier to understand multiplies and
divides, they are equally fast nowadays
 2015-02-28 14:14:30 -08:00
Björn Lindqvist ab75e3b05d VM: splits out the little ugly scan_next-object + goto-loop into a function trace_card() 2015-02-28 14:14:30 -08:00
Björn Lindqvist 8e91ca3e31 VM: simplification of the trace_partial_objects function 2015-02-28 14:14:30 -08:00
Björn Lindqvist a43a455990 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
Björn Lindqvist b5a206c587 VM: new function visit_mark_stack() to factor out the mark stack iteration 2015-02-28 14:14:29 -08:00
Björn Lindqvist 667e5768ba 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
Björn Lindqvist 5490c50217 VM: visit_roots and visit_contexts where always called in tandem, make a new method visit_all_roots that calls them both 2015-02-28 14:14:29 -08:00
Björn Lindqvist f5dc4afb2e VM: better error message in case factor_vm::store_external_address fails 2015-01-28 14:58:22 +00:00
Björn Lindqvist 434e4ef4b7 VM: fix the debug printing so that instead of always printing to std::cout, you supply the stream to print to 2015-01-28 14:58:21 +00:00
Björn Lindqvist d18c48c75b VM: possible fix for . the size of the stack frame appears to have been miscalculated in iterate_callstack which this commit fixes. 2015-01-15 09:29:14 +00:00
Björn Lindqvist ee5fd49b9e VM: simplified fixup_gc_workhorse::fixup_data by mering lots of functions only used once 2015-01-15 09:29:14 +00:00
Björn Lindqvist 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
Björn Lindqvist 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
Björn Lindqvist d2aea0f606 VM: replaced the reset_generation() generic method with one method for each generation 2015-01-15 09:29:14 +00:00
Björn Lindqvist 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
Björn Lindqvist b61eaa8a16 VM: the full_collector class isn't needed since it is only used once 2015-01-15 09:29:14 +00:00
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 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
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 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

Björn Lindqvist 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
Björn Lindqvist 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
Björn Lindqvist 11e906139b VM: code_block::scan, make it so the method always returns -1 if scan can't be determined, part of the fix for 2015-01-15 09:29:13 +00:00
Björn Lindqvist 8ee1f890f2 VM: refactoring intended to remove trace_*-methods that are just 
simple delegations to the data/code_visitor instances
 2015-01-15 09:29:12 +00:00

This reverts commit 378f208025.
 2014-12-04 11:46:28 -08:00
Doug Coleman 875d2421df vm: We don't want ambiguity for which print triggered on a gc error. Differentiate the error messages. 2014-12-04 10:35:32 -08:00

Björn Lindqvist 451fc12411 VM: redundant if, trace_cards() doesnt do anything for empty generations anyway 2014-12-04 10:23:33 -08:00
Björn Lindqvist 93134b949f VM: the aging_collector and nursery_collector classes aren't needed because they are just simple instatiations of copying_collector 2014-12-04 10:23:33 -08:00
Björn Lindqvist 423e983514 VM: refactoring to get rid of the megamorphic_call_stub and check_code_pointer() words 2014-12-04 10:23:33 -08:00
Björn Lindqvist 885b5c7043 VM: no need for a nursery_space class, it's just a bump_allocator 2014-12-04 10:23:33 -08:00
