Abdulaziz Ghuloum 64e54de392 Added two extra fields to the port data structure. 2007-12-18 15:36:56 -05:00
Abdulaziz Ghuloum 356a809970 the exit status due to calling (exit n) is 
: n            if n is a fixnum
  : EXIT_FAILURE otherwise

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.

BEFORE:
running stats for macro expansion:
    45 collections
    2558 ms elapsed cpu time, including 212 ms collecting
    2576 ms elapsed real time, including 216 ms collecting
    186972152 bytes allocated
running stats for code generation and serialization:
    86 collections
    4365 ms elapsed cpu time, including 1444 ms collecting
    4374 ms elapsed real time, including 1449 ms collecting
    362819096 bytes allocated
running stats for the entire bootstrap process:
    131 collections
    6928 ms elapsed cpu time, including 1657 ms collecting
    6953 ms elapsed real time, including 1666 ms collecting
    549818232 bytes allocated

Abdulaziz Ghuloum 23b71cee3c substantial speedup for new io layer 2007-12-12 21:22:05 -05:00
Abdulaziz Ghuloum af020f909b slight change to implementation of time-gmt-offset so that the 
gmt_off field of the tm struct is not used (not available in
cygwin).
 2007-12-11 19:32:34 -05:00
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 0e38534d2e New IO layer is installed. Still buggy in some area but can be used 
for bootstrapping at least.
 2007-12-10 07:28:03 -05:00

Abdulaziz Ghuloum ebc4deea60 Fixes bug 173001: r5rs values exported by rnrs library

  exact->inexact inexact->exact quotient modulo remainder string-set! string-fill!
 2007-11-30 05:13:01 -05:00
Abdulaziz Ghuloum a1adb6cc14 Missing initialization of code_ap and code_ep in ikarus-fasl.c 
caused segfault on freebsd.  The funny thing, I had initialization
code in a commented-out section.  Fun fun.
 2007-11-24 22:54:40 -05:00
Abdulaziz Ghuloum ccce44fffa Fixed dynamic loading problem in the cygwin port. Apparently, no 
one is using the bzr version of Ikarus under cygwin since it's been
broken for some time now.
 2007-11-23 02:29:46 -05:00
Abdulaziz Ghuloum 42daf68195 Added string-ci-hash and symbol-hash.

  (getenv "HOME") => "/Users/aghuloum"
  (getenv "FOO")  => ""

Abdulaziz Ghuloum 3b4d3097a1 Fixes bug 163540: allocation in bignum arithmetic does not garbage collect. 2007-11-18 10:37:13 -05:00
Abdulaziz Ghuloum 1afade6d43 * renamed ik_alloc to ik_unsafe_alloc since it was unsafe to call it 
in general (it did not collect on heap overflow).
 2007-11-18 09:12:00 -05:00
Abdulaziz Ghuloum 90759047b3 * The fasl loader has reduced the startup mmap frenzy for code 
objects from 5242 pages (almost one page per code object) down
  to 785 pages.  Special thanks to Michael Adams for counting the
  the number of pages that were used and touched at startup; without
  his help, I wouldn't have optimized it in about 10 minutes of
  coding time.
 2007-11-17 13:26:27 -05:00

  to /usr/local/lib/ikarus/ikarus.boot by default.
 2007-11-12 00:27:36 -05:00
Abdulaziz Ghuloum 5a6e106a44 * upgrades to new(er) versions of automake and autoconf.
