18    Description:
20    1. X86 fixes/changes
22       a.  The old code generated for SETcc was completely wrong.
23           The Intel optimization guide is VERY misleading.
25    2. ALPHA fixes/changes
27       a.  Added the instructions LDBU, LDWU, STB, STW as per Fermin's suggestion.
28       b.  Added a new mode byteWordLoadStores to the functor parameter to Alpha()
29       c.  Added reassociation code for address computation.

35    Description:
37    1. X86 fixes/changes
39       a.  x86Rewrite bug with MUL3 (found by Lal)
40       b.  Added the instructions FSTS, FSTL
42    2. PA-RISC fixes/changes
44       a.  B label should not be a delay slot candidate!  Why did this work?
45       b.  ADDT(32, REG(32, r), LI n) now generates one instruction instead of two,
46           as it should be.
47       c.  The assembly syntax for fstds and fstdd was wrong.
48       d.  Added the composite instruction COMICLR/LDO, which is the immediate
49           operand variant of COMCLR/LDO.
51    3. Generic MLRISC
53       a.  shuffle.sml rewritten to be slightly more efficient
54       b.  DIV bug in mltree-simplify fixed (found by Fermin)
56    4. Register Allocator
58       a.  I now release the interference graph earlier during spilling.
59           May improve memory usage.

65    Description:
67    1. Tools.registerStdShellCmdTool (from smlnj/cm/tool.cm) takes an
68    additional argument called "template" which is an optional string that
69    specifiel the layout of the tool command line.  See the CM manual for
70    explanation.
72    2. A special-purpose tool can be "regisitered" by simply dropping the
73    corresponding <...>-tool.cm (and/or <...>-ext.cm) into the same
74    directory where the .cm file lives that uses this tool.  (The
75    behavior/misfeature until now was to look for the tool description
76    files in the current working directory.)  As before, tool description
77    files could also be anchored -- in which case they can live anywhere
78    they like.  Following the recent e-mail discussion, this change should
79    make it easier to have special-purpose tools that are shipped together
80    with the sources of the program that uses them.

86    Description:
88    I added a re-written version of Dave's fixpt script to src/system.
89    Changes relative to the original version:
90      - sh-ified (not everybody has ksh)
91      - automatically figures out which architecture it runs on
92      - uses ./makeml a bit more cleverly
93      - never invokes ./installml (and, thus, does not clobber your
94        good and working installation of sml in case something goes wrong)
95      - accepts max iteration count using option "-iter <n>"
96      - accepts a "base" name using option "-base <base>"
98    It does not build any extraneous heap images but directly rebuilds
99    bin- and boot-hierarchies using makeml's "-rebuild" switch. Finally,
100    it can incorporate existing bin- and boot- hierarchies.  For example,
101    suppose the base is set to "sml" (which is the default).  Then it
102    successively builds
104            sml.bin.<arch>-unix and sml.boot.<arch>-unix
105    then    sml1.bin.<arch>-unix and sml1.boot.<arch>-unix
106    then    sml2.bin.<arch>-unix and sml2.boot.<arch>-unix
107    ...
108    then    sml<n>.bin.<arch>-unix and sml<n>.boot.<arch>-unix
110    and so on.  If any of these already exist, it will just use what's
111    there.  In particular, many people will have the initial set of bin
112    and boot files around, so this saves time for at least one full
113    rebuild.  Having sets of the form <base><k>.{bin,boot}.<arch>-unix for
114    <k>=1,2,... is normally not a good idea when invoking fixpt.  However,
115    they might be the result of an earlier partial run of fixpt (which
116    perhaps got accidentially killed).  In this case, fixpt will quickly
117    move through what exists before continuing where it left off earlier,
118    and, thus, saves a lot of time.

124    Description:
126    More assembly output problems involving the indexed addressing mode
127    on the x86 have been found and corrected. Thanks to Fermin Reig for the
128    fix.
130    The interface and implementation of the register allocator have been changed
131    slightly to accommodate the possibility to skip the register allocation
132    phases completely and go directly to memory allocation.  This is needed
133    for C-- use.

139    Description:
141    * Complete re-organization of library names.  Many libraries have been
142    consolidated so that they share the same path anchor.  For example,
143    all MLRISC-related libraries are anchored at MLRISC, most libraries that
144    are SML/NJ-specific are under "smlnj".  Notice that names like
145    host-cmb.cm or host-compiler.cm no longer exist.  See system/README
146    for a complete description of the new naming scheme.  Quick reference:
148       host-cmb.cm        -> smlnj/cmb.cm
149       host-compiler.cm   -> smlnj/compiler.cm
150       full-cm.cm         -> smlnj/cm.cm
151       <arch>-<os>.cm     -> smlnj/cmb/<arch>-<os>.cm
152       <arch>-compiler.cm -> smlnj/compiler/<arch>.cm
154    * Bug fixes in CM.
155        - exceptions in user code are being passed through (i.e., reach top level)
156        - more bugs in paranoia mode fixed
157        - bug related to checking group owners fixed
159    * New install.sh script that automagically fetches archive files:
160      The new file config/srcarchiveurl must contain the URL of the
161      (remote) directory that contains bin files (or other source archives).
162      If install.sh does not find the archive locally, it tries to get
163      it from that remote directory.
164      This should simplify installation further:  For machines that have
165      access to the internet, just fetch <version>-config.tgz, unpack it,
166      edit config/targets, and go (run config/install.sh).  The scipt will
167      fetch everything else that it might need all by itself.
169      For CVS users, this mechanism is not relevant for source archives, but
170      it is convenient for getting new sets of binfiles.
172      Archives should be tar files compressed with either gzip, compress, or
173      bzip2.  The script recognizes .tgz, .tar, tar.gz, tz, .tar.Z, and .tar.bz2.
