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.

56    Description:
57    
58    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.

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.

111  Description:  Description:
112    - 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)
