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>

17 :			Tag: blume_main_v110p26p1_1
18 :			Description:
19 :
20 :			I added a re-written version of Dave's fixpt script to src/system.
21 :			Changes relative to the original version:
22 :			- sh-ified (not everybody has ksh)
23 :			- automatically figures out which architecture it runs on
24 :			- uses ./makeml a bit more cleverly
25 :			- never invokes ./installml (and, thus, does not clobber your
26 :			good and working installation of sml in case something goes wrong)
27 :			- accepts max iteration count using option "-iter <n>"
28 :			- accepts a "base" name using option "-base <base>"
29 :
30 :			It does not build any extraneous heap images but directly rebuilds
31 :			bin- and boot-hierarchies using makeml's "-rebuild" switch. Finally,
32 :			it can incorporate existing bin- and boot- hierarchies. For example,
33 :			suppose the base is set to "sml" (which is the default). Then it
34 :			successively builds
35 :
36 :			sml.bin.<arch>-unix and sml.boot.<arch>-unix
37 :			then sml1.bin.<arch>-unix and sml1.boot.<arch>-unix
38 :			then sml2.bin.<arch>-unix and sml2.boot.<arch>-unix
39 :			...
40 :			then sml<n>.bin.<arch>-unix and sml<n>.boot.<arch>-unix
41 :
42 :			and so on. If any of these already exist, it will just use what's
43 :			there. In particular, many people will have the initial set of bin
44 :			and boot files around, so this saves time for at least one full
45 :			rebuild. Having sets of the form <base><k>.{bin,boot}.<arch>-unix for
46 :			<k>=1,2,... is normally not a good idea when invoking fixpt. However,
47 :			they might be the result of an earlier partial run of fixpt (which
48 :			perhaps got accidentially killed). In this case, fixpt will quickly
49 :			move through what exists before continuing where it left off earlier,
50 :			and, thus, saves a lot of time.

54 :			Date: 00/03/10 02:20:00
55 :			Tag: leunga-20000310-fix_x86_asm_ra
56 :			Description:
57 :	dbm	570
58 :	leunga	576	More assembly output problems involving the indexed addressing mode
59 :			on the x86 have been found and corrected. Thanks to Fermin Reig for the
60 :			fix.
61 :
62 :			The interface and implementation of the register allocator have been changed
63 :			slightly to accommodate the possibility to skip the register allocation
64 :			phases completely and go directly to memory allocation. This is needed
65 :			for C-- use.

70 :			Tag: blume_main_v110p26p1_0
71 :			Description:
72 :
73 :			* Complete re-organization of library names. Many libraries have been
74 :			consolidated so that they share the same path anchor. For example,
75 :			all MLRISC-related libraries are anchored at MLRISC, most libraries that
76 :			are SML/NJ-specific are under "smlnj". Notice that names like
77 :			host-cmb.cm or host-compiler.cm no longer exist. See system/README
78 :			for a complete description of the new naming scheme. Quick reference:
79 :
80 :			host-cmb.cm -> smlnj/cmb.cm
81 :			host-compiler.cm -> smlnj/compiler.cm
82 :			full-cm.cm -> smlnj/cm.cm
83 :			<arch>-<os>.cm -> smlnj/cmb/<arch>-<os>.cm
84 :			<arch>-compiler.cm -> smlnj/compiler/<arch>.cm
85 :
86 :			* Bug fixes in CM.
87 :			- exceptions in user code are being passed through (i.e., reach top level)
88 :			- more bugs in paranoia mode fixed
89 :			- bug related to checking group owners fixed
90 :
91 :			* New install.sh script that automagically fetches archive files:
92 :			The new file config/srcarchiveurl must contain the URL of the
93 :			(remote) directory that contains bin files (or other source archives).
94 :			If install.sh does not find the archive locally, it tries to get
95 :			it from that remote directory.
96 :			This should simplify installation further: For machines that have
97 :			access to the internet, just fetch <version>-config.tgz, unpack it,
98 :			edit config/targets, and go (run config/install.sh). The scipt will
99 :			fetch everything else that it might need all by itself.
100 :
101 :			For CVS users, this mechanism is not relevant for source archives, but
102 :			it is convenient for getting new sets of binfiles.
103 :
104 :			Archives should be tar files compressed with either gzip, compress, or
105 :			bzip2. The script recognizes .tgz, .tar, tar.gz, tz, .tar.Z, and .tar.bz2.

108 :			Name: Matthias Blume
109 :	blume	572	Date: 2000/03/07 04:01:04
110 :			Tag: blume_main_v110_26_2
111 :	dbm	570	Description:
112 :	blume	572	- size info in BOOTLIST
113 :			* no fixed upper limits for number of bootfiles or length of
114 :			bootfile names in runtime
115 :			* falling back to old behavior if no BOOTLIST size info found
116 :			- allocation size heuristics in .run-sml
117 :			* tries to read cache size from /proc/cpuinfo (this is important for
118 :			small-cache Celeron systems!)
119 :			- install.sh robustified
120 :			- CM manual updates
121 :			- paranoid mode
122 :			* no more CMB.deliver() (i.e., all done by CMB.make())
123 :			* can re-use existing sml.boot.* files
124 :			* init.cmi now treated as library
125 :			* library stamps for consistency checks
126 :			- sml.boot.<arch>-<os>/PIDMAP file
127 :			* This file is read by the CM startup code. This is used to minimize
128 :			the amount of dynamic state that needs to be stowed away for the
129 :			purpose of sharing between interactive system and user code.
130 :			- CM.Anchor.anchor instead of CM.Anchor.{set,cancel}
131 :			* Upon request by Elsa. Anchors now controlled by get-set-pair
132 :			like most other CM state variables.
133 :			- Compiler.CMSA eliminated
134 :			* No longer supported by CM anyway.
135 :			- fixed bugs in pickler that kept biting Stefan
136 :			* past refs to past refs (was caused by the possibility that
137 :			ad-hoc sharing is more discriminating than hash-cons sharing)
138 :			* integer overflow on LargeInt.minInt
139 :			- ml-{lex,yacc} build scripts now use new mechanism
140 :			for building standalone programs
141 :			- fixed several gcc -Wall warnings that were caused by missing header
142 :			files, missing initializations, etc., in runtime (not all warnings
143 :			eliminated, though)
