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    
36       a.  shuffle.sml rewritten to be slightly more efficient
37       b.  DIV bug in mltree-simplify fixed (found by Fermin)
38    
39    4. Register Allocator
40    
41       a.  I now release the interference graph earlier during spilling.
42           May improve memory usage.

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.

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.
