Original Path: sml/trunk/HISTORY

1 : dbm 570 This is the HISTORY file for the Yale SML/NJ CVS repository.
2 :    
3 :     An entry should be made for _every_ commit to the repository.
4 :     The entries in this file will be used when creating the README
5 :     for new versions, so keep that in mind when writing the
6 :     description.
7 :    
8 :     The form of an entry should be:
9 :    
10 :     Name:
11 :     Date:
12 :     Tag: <post-commit CVS tag>
13 :     Description:
14 : leunga 576 ----------------------------------------------------------------------
15 :     Name: Allen Leung
16 :     Date: 00/03/10 02:20:00
17 :     Tag: leunga-20000310-fix_x86_asm_ra
18 :     Description:
19 : dbm 570
20 : leunga 576 More assembly output problems involving the indexed addressing mode
21 :     on the x86 have been found and corrected. Thanks to Fermin Reig for the
22 :     fix.
23 :    
24 :     The interface and implementation of the register allocator have been changed
25 :     slightly to accommodate the possibility to skip the register allocation
26 :     phases completely and go directly to memory allocation. This is needed
27 :     for C-- use.

30 : blume 572 Name: Matthias Blume
31 : blume 575 Date: 00/03/09 10:23:53
32 :     Tag: blume_main_v110p26p1_0
33 :     Description:
34 :    
35 :     * Complete re-organization of library names. Many libraries have been
36 :     consolidated so that they share the same path anchor. For example,
37 :     all MLRISC-related libraries are anchored at MLRISC, most libraries that
38 :     are SML/NJ-specific are under "smlnj". Notice that names like
39 :     host-cmb.cm or host-compiler.cm no longer exist. See system/README
40 :     for a complete description of the new naming scheme. Quick reference:
41 :    
42 :     host-cmb.cm -> smlnj/cmb.cm
43 :     host-compiler.cm -> smlnj/compiler.cm
44 :     full-cm.cm -> smlnj/cm.cm
45 :     <arch>-<os>.cm -> smlnj/cmb/<arch>-<os>.cm
46 :     <arch>-compiler.cm -> smlnj/compiler/<arch>.cm
47 :    
48 :     * Bug fixes in CM.
49 :     - exceptions in user code are being passed through (i.e., reach top level)
50 :     - more bugs in paranoia mode fixed
51 :     - bug related to checking group owners fixed
52 :    
53 :     * New install.sh script that automagically fetches archive files:
54 :     The new file config/srcarchiveurl must contain the URL of the
55 :     (remote) directory that contains bin files (or other source archives).
56 :     If install.sh does not find the archive locally, it tries to get
57 :     it from that remote directory.
58 :     This should simplify installation further: For machines that have
59 :     access to the internet, just fetch <version>-config.tgz, unpack it,
60 :     edit config/targets, and go (run config/install.sh). The scipt will
61 :     fetch everything else that it might need all by itself.
62 :    
63 :     For CVS users, this mechanism is not relevant for source archives, but
64 :     it is convenient for getting new sets of binfiles.
65 :    
66 :     Archives should be tar files compressed with either gzip, compress, or
67 :     bzip2. The script recognizes .tgz, .tar, tar.gz, tz, .tar.Z, and .tar.bz2.

70 :     Name: Matthias Blume
71 : blume 572 Date: 2000/03/07 04:01:04
72 :     Tag: blume_main_v110_26_2
73 : dbm 570 Description:
74 : blume 572 - size info in BOOTLIST
75 :     * no fixed upper limits for number of bootfiles or length of
76 :     bootfile names in runtime
77 :     * falling back to old behavior if no BOOTLIST size info found
78 :     - allocation size heuristics in .run-sml
79 :     * tries to read cache size from /proc/cpuinfo (this is important for
80 :     small-cache Celeron systems!)
81 :     - install.sh robustified
82 :     - CM manual updates
83 :     - paranoid mode
84 :     * no more CMB.deliver() (i.e., all done by CMB.make())
85 :     * can re-use existing sml.boot.* files
86 :     * init.cmi now treated as library
87 :     * library stamps for consistency checks
88 :     - sml.boot.<arch>-<os>/PIDMAP file
89 :     * This file is read by the CM startup code. This is used to minimize
90 :     the amount of dynamic state that needs to be stowed away for the
91 :     purpose of sharing between interactive system and user code.
92 :     - CM.Anchor.anchor instead of CM.Anchor.{set,cancel}
93 :     * Upon request by Elsa. Anchors now controlled by get-set-pair
94 :     like most other CM state variables.
95 :     - Compiler.CMSA eliminated
96 :     * No longer supported by CM anyway.
97 :     - fixed bugs in pickler that kept biting Stefan
98 :     * past refs to past refs (was caused by the possibility that
99 :     ad-hoc sharing is more discriminating than hash-cons sharing)
100 :     * integer overflow on LargeInt.minInt
101 :     - ml-{lex,yacc} build scripts now use new mechanism
102 :     for building standalone programs
103 :     - fixed several gcc -Wall warnings that were caused by missing header
104 :     files, missing initializations, etc., in runtime (not all warnings
105 :     eliminated, though)
