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:

15 : leunga 580 Name: Allen Leung
16 :     Date: 2000/03/22 01:23:00
17 :     Tag: leunga-20000322-fix_x86_hppa_ra
18 :     Description:
19 :    
20 :     1. X86 fixes/changes
21 :    
22 :     a. x86Rewrite bug with MUL3 (found by Lal)
23 :     b. Added the instructions FSTS, FSTL
24 :    
25 :     2. PA-RISC fixes/changes
26 :    
27 :     a. B label should not be a delay slot candidate! Why did this work?
28 :     b. ADDT(32, REG(32, r), LI n) now generates one instruction instead of two,
29 :     as it should be.
30 :     c. The assembly syntax for fstds and fstdd was wrong.
31 :     d. Added the composite instruction COMICLR/LDO, which is the immediate
32 :     operand variant of COMCLR/LDO.
33 :    
34 :     3. Generic MLRISC
35 :

47 :     Tag: blume_main_v110p26p1_2
48 :     Description:
49 :    
50 :     1. Tools.registerStdShellCmdTool (from smlnj/cm/tool.cm) takes an
51 :     additional argument called "template" which is an optional string that
52 :     specifiel the layout of the tool command line. See the CM manual for
53 :     explanation.
54 :    
55 :     2. A special-purpose tool can be "regisitered" by simply dropping the
56 :     corresponding <...>-tool.cm (and/or <...>-ext.cm) into the same
57 :     directory where the .cm file lives that uses this tool. (The
58 :     behavior/misfeature until now was to look for the tool description
59 :     files in the current working directory.) As before, tool description
60 :     files could also be anchored -- in which case they can live anywhere
61 :     they like. Following the recent e-mail discussion, this change should
62 :     make it easier to have special-purpose tools that are shipped together
63 :     with the sources of the program that uses them.

66 :     Name: Matthias Blume
67 : blume 577 Date: 2000/03/10 07:48:34
68 :     Tag: blume_main_v110p26p1_1
69 :     Description:
70 :    
71 :     I added a re-written version of Dave's fixpt script to src/system.
72 :     Changes relative to the original version:
73 :     - sh-ified (not everybody has ksh)
74 :     - automatically figures out which architecture it runs on
75 :     - uses ./makeml a bit more cleverly
76 :     - never invokes ./installml (and, thus, does not clobber your
77 :     good and working installation of sml in case something goes wrong)
78 :     - accepts max iteration count using option "-iter <n>"
79 :     - accepts a "base" name using option "-base <base>"
80 :    
81 :     It does not build any extraneous heap images but directly rebuilds
82 :     bin- and boot-hierarchies using makeml's "-rebuild" switch. Finally,
83 :     it can incorporate existing bin- and boot- hierarchies. For example,
84 :     suppose the base is set to "sml" (which is the default). Then it
85 :     successively builds
86 :    
87 :     sml.bin.<arch>-unix and sml.boot.<arch>-unix
88 :     then sml1.bin.<arch>-unix and sml1.boot.<arch>-unix
89 :     then sml2.bin.<arch>-unix and sml2.boot.<arch>-unix
90 :     ...
91 :     then sml<n>.bin.<arch>-unix and sml<n>.boot.<arch>-unix
92 :    
93 :     and so on. If any of these already exist, it will just use what's
94 :     there. In particular, many people will have the initial set of bin
95 :     and boot files around, so this saves time for at least one full
96 :     rebuild. Having sets of the form <base><k>.{bin,boot}.<arch>-unix for
97 :     <k>=1,2,... is normally not a good idea when invoking fixpt. However,
98 :     they might be the result of an earlier partial run of fixpt (which
99 :     perhaps got accidentially killed). In this case, fixpt will quickly
100 :     move through what exists before continuing where it left off earlier,
101 :     and, thus, saves a lot of time.

104 : leunga 576 Name: Allen Leung
105 :     Date: 00/03/10 02:20:00
106 :     Tag: leunga-20000310-fix_x86_asm_ra
107 :     Description:
108 : dbm 570
109 : leunga 576 More assembly output problems involving the indexed addressing mode
110 :     on the x86 have been found and corrected. Thanks to Fermin Reig for the
111 :     fix.
112 :    
113 :     The interface and implementation of the register allocator have been changed
114 :     slightly to accommodate the possibility to skip the register allocation
115 :     phases completely and go directly to memory allocation. This is needed
116 :     for C-- use.

119 : blume 572 Name: Matthias Blume
120 : blume 575 Date: 00/03/09 10:23:53
121 :     Tag: blume_main_v110p26p1_0
122 :     Description:
123 :    
124 :     * Complete re-organization of library names. Many libraries have been
125 :     consolidated so that they share the same path anchor. For example,
126 :     all MLRISC-related libraries are anchored at MLRISC, most libraries that
127 :     are SML/NJ-specific are under "smlnj". Notice that names like
128 :     host-cmb.cm or host-compiler.cm no longer exist. See system/README
129 :     for a complete description of the new naming scheme. Quick reference:
130 :    
131 :     host-cmb.cm -> smlnj/cmb.cm
132 :     host-compiler.cm -> smlnj/compiler.cm
133 :     full-cm.cm -> smlnj/cm.cm
134 :     <arch>-<os>.cm -> smlnj/cmb/<arch>-<os>.cm
135 :     <arch>-compiler.cm -> smlnj/compiler/<arch>.cm
136 :    
137 :     * Bug fixes in CM.
138 :     - exceptions in user code are being passed through (i.e., reach top level)
139 :     - more bugs in paranoia mode fixed
140 :     - bug related to checking group owners fixed
141 :    
142 :     * New install.sh script that automagically fetches archive files:
143 :     The new file config/srcarchiveurl must contain the URL of the
144 :     (remote) directory that contains bin files (or other source archives).
145 :     If install.sh does not find the archive locally, it tries to get
146 :     it from that remote directory.
147 :     This should simplify installation further: For machines that have
148 :     access to the internet, just fetch <version>-config.tgz, unpack it,
149 :     edit config/targets, and go (run config/install.sh). The scipt will
150 :     fetch everything else that it might need all by itself.
151 :    
152 :     For CVS users, this mechanism is not relevant for source archives, but
153 :     it is convenient for getting new sets of binfiles.
154 :    
155 :     Archives should be tar files compressed with either gzip, compress, or
156 :     bzip2. The script recognizes .tgz, .tar, tar.gz, tz, .tar.Z, and .tar.bz2.

159 :     Name: Matthias Blume
160 : blume 572 Date: 2000/03/07 04:01:04
161 :     Tag: blume_main_v110_26_2
162 : dbm 570 Description:
163 : blume 572 - size info in BOOTLIST
164 :     * no fixed upper limits for number of bootfiles or length of
165 :     bootfile names in runtime
166 :     * falling back to old behavior if no BOOTLIST size info found
167 :     - allocation size heuristics in .run-sml
168 :     * tries to read cache size from /proc/cpuinfo (this is important for
169 :     small-cache Celeron systems!)
170 :     - install.sh robustified
171 :     - CM manual updates
172 :     - paranoid mode
173 :     * no more CMB.deliver() (i.e., all done by CMB.make())
174 :     * can re-use existing sml.boot.* files
175 :     * init.cmi now treated as library
176 :     * library stamps for consistency checks
177 :     - sml.boot.<arch>-<os>/PIDMAP file
178 :     * This file is read by the CM startup code. This is used to minimize
179 :     the amount of dynamic state that needs to be stowed away for the
180 :     purpose of sharing between interactive system and user code.
181 :     - CM.Anchor.anchor instead of CM.Anchor.{set,cancel}
182 :     * Upon request by Elsa. Anchors now controlled by get-set-pair
183 :     like most other CM state variables.
184 :     - Compiler.CMSA eliminated
185 :     * No longer supported by CM anyway.
186 :     - fixed bugs in pickler that kept biting Stefan
187 :     * past refs to past refs (was caused by the possibility that
188 :     ad-hoc sharing is more discriminating than hash-cons sharing)
189 :     * integer overflow on LargeInt.minInt
190 :     - ml-{lex,yacc} build scripts now use new mechanism
191 :     for building standalone programs
192 :     - fixed several gcc -Wall warnings that were caused by missing header
193 :     files, missing initializations, etc., in runtime (not all warnings
194 :     eliminated, though)
