Abdulaziz Ghuloum af233a2ac2 added post-gc-hooks, a list of thunks that are invoked after garbage 
collection.
 2009-07-30 14:19:46 +03:00
Abdulaziz Ghuloum 75d2756bd2 fixed serious GC bug that's exhibited when guardians have protected 
objects that survive 256 collections.
 2008-12-08 01:43:23 -05:00
Abdulaziz Ghuloum d2022faf53 fixed a few gcc warnings as reported in bug 288824. 2008-10-29 13:54:06 -04:00
Abdulaziz Ghuloum 876ab09eee - gc during callbacks now works. 
- system continuations are now maintained as part of the list in
  pcb->next_k.
 2008-09-23 01:49:06 -04:00
Abdulaziz Ghuloum df4cb7a6ce fixed an off-by-one bug in ffi callbacks. 2008-09-23 00:24:41 -04:00
Abdulaziz Ghuloum afc9bff07f - added experimental pointer manipulation primitives. 2008-09-06 06:01:39 -07:00
Abdulaziz Ghuloum acc9940379 fixed gc bug in 64-bit mode along with another 64-bit bug in the 
assembler when addressing using special %eax/%rax instructions.
 2008-07-21 22:07:31 -07:00
Abdulaziz Ghuloum 78d9fa1f42 In 64-bit, ikarus now passes all tests, can recompile itself, 
and runs all benchmarks (inefficiently but correctly).
 2008-07-20 00:14:09 -07:00
Abdulaziz Ghuloum 4f48c55bfc all existing tests pass under 64-bit 2008-07-19 14:41:06 -07:00
Abdulaziz Ghuloum 81a1a640df more progress on the AMD64 front, fixing more numeric and more cogen 
64-bit bugs.
 2008-07-18 22:21:57 -07:00
Abdulaziz Ghuloum 01c4afa320 Major work towards the AMD64 port. Most important of which is that 
continuations work, more assembly instructions are testing in 64-bit
mode, and some arithmetic operations (shift-right, etc.) have been
fixed by removing some 32-bit dependencies.
 2008-07-18 01:35:13 -07:00
Abdulaziz Ghuloum 81db526510 Fixed all warnings while compiling with -Wall 2008-06-04 00:54:53 -07:00

Abdulaziz Ghuloum 82140f87ba - Added complex numbers representation (exact complex only). 
- Added make-rectangular.
- Added the ability to display complex numbers.
 2008-05-18 20:39:41 -07:00

Abdulaziz Ghuloum 2dc4542148 Reimplemented the guardians collector which was yellowing out since 
the last update to the GC.  All tests now run without a glitch.
 2008-01-12 17:32:43 -05:00

Abdulaziz Ghuloum 66e9cd6415 ikarus now compiles cleanly (but still unrunnable) in 64-bit mode. 2008-01-01 21:42:52 -05:00
Abdulaziz Ghuloum e0909d76fe changed type of ikptr to unsigned int now and removed ikint. 2008-01-01 21:08:07 -05:00
Abdulaziz Ghuloum 15ea12f915 cleanup of the C files to make all ikptr->int casts ikptr->long int 2008-01-01 04:24:36 -05:00
Abdulaziz Ghuloum 5d33921c9e changed type of ikp from unsigned char* to char* 2007-12-23 13:37:48 -05:00
Abdulaziz Ghuloum d162c1cc25 moved definition of HEAPSIZE to ikarus-data.h 2007-12-20 03:51:43 -05:00
Abdulaziz Ghuloum 372c3e369b Change of strategy in the garbage collector. 
Previously: when a generation (say 2) is collected, 
  everything in gen 0 moves to gen 1
  everything in gen 1 moves to gen 2
  everything in gen 2 moves to gen 3

Now: when a generation (say 2 again) is collected
  everything in gen 0 moves to gen 3
  everything in gen 1 moves to gen 3
  everything in gen 2 moves to gen 3

So, some objects get a leap from young to old if they're lucky to be
in the right time.

Consequences: when an object is moved by the collector, we don't
need to track old->new pointers and masks because all moved objects
are clean now.  This both simplifies the collector and makes it more
efficient and might open the door for further optimization
opportunities.  For bootstrap time, we get about 5% overall 
saving and about 20% GC-time saving.  Not bad.

Abdulaziz Ghuloum b3f30bebff forgot to include <sys/time.h> in ikarys-collect.c (MacOS does not 
complain about implicit declaration of gettimeofday).
 2007-12-10 15:06:47 -05:00
Abdulaziz Ghuloum 7d7ceb6480 Weeded out gcc warnings and added -Wall as a configure flag. 2007-12-10 15:02:25 -05:00
