21    Bug fix for c-calls on x86 (having to do with how char- and
22    short-arguments are being handled).

30    Another day of fiddling with the FFI...
31    
32    1. Bug fix/workaround:  CKIT does not complain about negative array
33       dimensions, so ml-nlffigen has to guard itself against this possibility.
34       (Otherwise a negative dimension would send it into an infinite loop.)
35    
36    2. Some of the abstract types (light objects, light pointers, most "base"
37       types) in structure C are now eqtypes.
38    
39    3. Added constructors and test functions for NULL function pointers.

47    Made config/srcarchiveurl point to a new place.  (Will provide boot
48    files shortly.)

50    Maybe we christen this to be 110.38?

56    Description:
57    
58    Today's FFI fiddling:
59    
60      - Provided a structure CGetSet with "convenient" versions of C.Get.* and
61        C.Set.* that use concrete (MLRep.*) arguments and results instead
62        of abstract ones.
63    
64      - Provided word-style bit operations etc. for "int" representation
65        types in MLRep.S<Foo>Bitops where <Foo> ranges over Char, Int, Short,
66        and Long.

72    Description:
73    
74    Now that x86-fast-fp seems to be working, I turned it back on again
75    by default.  (Seems to work fine now, even with the FFI.)
76    
77    Other than that, I added some documentation about the FFI to
78    src/ml-nlffigen/README and updated the FFI test examples in
79    src/ml-nlffi-lib/Tests/*.

85    Description:
86    
87       1. Fixed a problem with handling return fp values when x86's fast fp
88          mode is turned on.
89    
90       2. Minor pretty printing fix for cellset.  Print %st(0) as %st(0) instead
91          of %f32.
92    
93       3. Added a constructor INT32lit to the ast of MLRISC tools.

99    Description:
100    
101    More fiddling with the FFI interface:
102    
103     - Make constness 'c instead of rw wherever possible.  This eliminates
104       the need for certain explicit coercions.  (However, due to ML's
105       value polymorphism, there will still be many cases where explicit
106       coercions are necessary.  Phantom types are not the whole answer
107       to modeling a subtyping relationship in ML.)
108    
109     - ro/rw coersions for pointers added.  (Avoids the detour through */&.)
110    
111     - "printf" test example added to src/ml-nlffi-lib/Tests.  (Demonstrates
112       clumsy workaround for varargs problem.)

120    1. Since COPY instructions are no longer native to the architecture,
121       a generic functor can be used to implement the expandCopies function.
122    
123    2. Allowed EXPORT and IMPORT pseudo-op declarations to appear inside a
124       TEXT segment.
