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:

18 :			Description:
19 :
20 :			1. Tools.registerStdShellCmdTool (from smlnj/cm/tool.cm) takes an
21 :			additional argument called "template" which is an optional string that
22 :			specifiel the layout of the tool command line. See the CM manual for
23 :			explanation.
24 :
25 :			2. A special-purpose tool can be "regisitered" by simply dropping the
26 :			corresponding <...>-tool.cm (and/or <...>-ext.cm) into the same
27 :			directory where the .cm file lives that uses this tool. (The
28 :			behavior/misfeature until now was to look for the tool description
29 :			files in the current working directory.) As before, tool description
30 :			files could also be anchored -- in which case they can live anywhere
31 :			they like. Following the recent e-mail discussion, this change should
32 :			make it easier to have special-purpose tools that are shipped together
33 :			with the sources of the program that uses them.

38 :			Tag: blume_main_v110p26p1_1
39 :			Description:
40 :
41 :			I added a re-written version of Dave's fixpt script to src/system.
42 :			Changes relative to the original version:
43 :			- sh-ified (not everybody has ksh)
44 :			- automatically figures out which architecture it runs on
45 :			- uses ./makeml a bit more cleverly
46 :			- never invokes ./installml (and, thus, does not clobber your
47 :			good and working installation of sml in case something goes wrong)
48 :			- accepts max iteration count using option "-iter <n>"
49 :			- accepts a "base" name using option "-base <base>"
50 :
51 :			It does not build any extraneous heap images but directly rebuilds
52 :			bin- and boot-hierarchies using makeml's "-rebuild" switch. Finally,
53 :			it can incorporate existing bin- and boot- hierarchies. For example,
54 :			suppose the base is set to "sml" (which is the default). Then it
55 :			successively builds
56 :
57 :			sml.bin.<arch>-unix and sml.boot.<arch>-unix
58 :			then sml1.bin.<arch>-unix and sml1.boot.<arch>-unix
59 :			then sml2.bin.<arch>-unix and sml2.boot.<arch>-unix
60 :			...
61 :			then sml<n>.bin.<arch>-unix and sml<n>.boot.<arch>-unix
62 :
63 :			and so on. If any of these already exist, it will just use what's
64 :			there. In particular, many people will have the initial set of bin
65 :			and boot files around, so this saves time for at least one full
66 :			rebuild. Having sets of the form <base><k>.{bin,boot}.<arch>-unix for
67 :			<k>=1,2,... is normally not a good idea when invoking fixpt. However,
68 :			they might be the result of an earlier partial run of fixpt (which
69 :			perhaps got accidentially killed). In this case, fixpt will quickly
70 :			move through what exists before continuing where it left off earlier,
71 :			and, thus, saves a lot of time.

76 :			Tag: leunga-20000310-fix_x86_asm_ra
77 :			Description:
78 :	dbm	570
79 :	leunga	576	More assembly output problems involving the indexed addressing mode
80 :			on the x86 have been found and corrected. Thanks to Fermin Reig for the
81 :			fix.
82 :
83 :			The interface and implementation of the register allocator have been changed
84 :			slightly to accommodate the possibility to skip the register allocation
85 :			phases completely and go directly to memory allocation. This is needed
86 :			for C-- use.

90 :	blume	575	Date: 00/03/09 10:23:53
91 :			Tag: blume_main_v110p26p1_0
92 :			Description:
93 :
94 :			* Complete re-organization of library names. Many libraries have been
95 :			consolidated so that they share the same path anchor. For example,
96 :			all MLRISC-related libraries are anchored at MLRISC, most libraries that
97 :			are SML/NJ-specific are under "smlnj". Notice that names like
98 :			host-cmb.cm or host-compiler.cm no longer exist. See system/README
99 :			for a complete description of the new naming scheme. Quick reference:
100 :
101 :			host-cmb.cm -> smlnj/cmb.cm
102 :			host-compiler.cm -> smlnj/compiler.cm
103 :			full-cm.cm -> smlnj/cm.cm
104 :			<arch>-<os>.cm -> smlnj/cmb/<arch>-<os>.cm
105 :			<arch>-compiler.cm -> smlnj/compiler/<arch>.cm
106 :
107 :			* Bug fixes in CM.
108 :			- exceptions in user code are being passed through (i.e., reach top level)
109 :			- more bugs in paranoia mode fixed
110 :			- bug related to checking group owners fixed
111 :
112 :			* New install.sh script that automagically fetches archive files:
113 :			The new file config/srcarchiveurl must contain the URL of the
114 :			(remote) directory that contains bin files (or other source archives).
115 :			If install.sh does not find the archive locally, it tries to get
116 :			it from that remote directory.
117 :			This should simplify installation further: For machines that have
118 :			access to the internet, just fetch <version>-config.tgz, unpack it,
119 :			edit config/targets, and go (run config/install.sh). The scipt will
120 :			fetch everything else that it might need all by itself.
121 :
122 :			For CVS users, this mechanism is not relevant for source archives, but
123 :			it is convenient for getting new sets of binfiles.
124 :
125 :			Archives should be tar files compressed with either gzip, compress, or
126 :			bzip2. The script recognizes .tgz, .tar, tar.gz, tz, .tar.Z, and .tar.bz2.

131 :			Tag: blume_main_v110_26_2
132 :	dbm	570	Description:
133 :	blume	572	- size info in BOOTLIST
134 :			* no fixed upper limits for number of bootfiles or length of
135 :			bootfile names in runtime
136 :			* falling back to old behavior if no BOOTLIST size info found
137 :			- allocation size heuristics in .run-sml
138 :			* tries to read cache size from /proc/cpuinfo (this is important for
139 :			small-cache Celeron systems!)
140 :			- install.sh robustified
141 :			- CM manual updates
142 :			- paranoid mode
143 :			* no more CMB.deliver() (i.e., all done by CMB.make())
144 :			* can re-use existing sml.boot.* files
145 :			* init.cmi now treated as library
146 :			* library stamps for consistency checks
147 :			- sml.boot.<arch>-<os>/PIDMAP file
148 :			* This file is read by the CM startup code. This is used to minimize
149 :			the amount of dynamic state that needs to be stowed away for the
150 :			purpose of sharing between interactive system and user code.
151 :			- CM.Anchor.anchor instead of CM.Anchor.{set,cancel}
152 :			* Upon request by Elsa. Anchors now controlled by get-set-pair
153 :			like most other CM state variables.
154 :			- Compiler.CMSA eliminated
155 :			* No longer supported by CM anyway.
156 :			- fixed bugs in pickler that kept biting Stefan
157 :			* past refs to past refs (was caused by the possibility that
158 :			ad-hoc sharing is more discriminating than hash-cons sharing)
159 :			* integer overflow on LargeInt.minInt
160 :			- ml-{lex,yacc} build scripts now use new mechanism
161 :			for building standalone programs
162 :			- fixed several gcc -Wall warnings that were caused by missing header
163 :			files, missing initializations, etc., in runtime (not all warnings
164 :			eliminated, though)
