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.
