30    John Reppy:  Changes c-calls API to accept client-callback for
31    allocating extra stack space.
32    me: Corresponding changes to mlriscGen (using a dummy argument that
33        does not change the current behavior).

47    Description:
48    
49    0. Retracted earlier 110.38.  (The Release_110_38 tag has been replaced
50       with blume-Release_110_38-retracted.)
51    
52    1. Fixed a problem with incorrect rounding modes in real64.sml.
53       (Thanks to Andrew Mccreight <andrew.mccreight@yale.edu>.)
54    
55    2. A bug in ml-nlffigen related to the handling of unnamed structs, unions,
56       and enums fixed.  The naming of corresponding ML identifiers should
57       now be consistent again.

63    Description:
64    
65       Added a target called nowhere in the configuration scripts.
66       Enabling this will build the MLRISC 'nowhere' tool (for translating
67       programs with where-clauses into legal SML code) during installation.

73    Description:
74    
75    Call it a (working) release!  Version is 110.38. Bootfiles are ready.
76    
77    README will be added later.
78    
79    !!! NOTE:  Re-tagged as blume-Release_110_38-retracted. Original tag
80    (Release_110_38) removed.  Reason: Last-minute bug fixes.

85    Tag: blume-20020125-ffi
86    Description:
87    
88    A large number of tweaks and improvements to ml-nlffi-lib and
89    ml-nlffigen:
90    
91       - ML represenation types have been streamlined
92       - getter and setter functions work with concrete values, not abstract
93         ones where possible
94       - ml-nlffigen command line more flexible (see README file there)
95       - some bugs have been fixed (hopefully)

100    Tag: george-20020124-risc-ra-interface
101    Description:
102    
103       There is a dramatic simplification in the interface to the
104       register allocator for RISC architectures as a result of making
105       parallel copy instructions explicit.

110    Tag: blume-20020122-x86-ccalls
111    Description:
112    
113    Bug fix for c-calls on x86 (having to do with how char- and
114    short-arguments are being handled).
115

120    Description:
121    
122    Another day of fiddling with the FFI...
123    
124    1. Bug fix/workaround:  CKIT does not complain about negative array
125       dimensions, so ml-nlffigen has to guard itself against this possibility.
126       (Otherwise a negative dimension would send it into an infinite loop.)
127    
128    2. Some of the abstract types (light objects, light pointers, most "base"
129       types) in structure C are now eqtypes.
130    
131    3. Added constructors and test functions for NULL function pointers.

137    Description:
138    
139    Made config/srcarchiveurl point to a new place.  (Will provide boot
140    files shortly.)
141    
142    Maybe we christen this to be 110.38?

147    Tag: blume-20020118-more-ffifiddle
148    Description:
149    
150    Today's FFI fiddling:
151    
152      - Provided a structure CGetSet with "convenient" versions of C.Get.* and
153        C.Set.* that use concrete (MLRep.*) arguments and results instead
154        of abstract ones.
155    
156      - Provided word-style bit operations etc. for "int" representation
157        types in MLRep.S<Foo>Bitops where <Foo> ranges over Char, Int, Short,
158        and Long.

163    Tag: blume-20020118-use-x86-fp
164    Description:
165    
166    Now that x86-fast-fp seems to be working, I turned it back on again
167    by default.  (Seems to work fine now, even with the FFI.)
168    
169    Other than that, I added some documentation about the FFI to
170    src/ml-nlffigen/README and updated the FFI test examples in
171    src/ml-nlffi-lib/Tests/*.

176    Tag: leunga-20020117-x86-fast-fp-call
177    Description:
178    
179       1. Fixed a problem with handling return fp values when x86's fast fp
180          mode is turned on.
181    
182       2. Minor pretty printing fix for cellset.  Print %st(0) as %st(0) instead
183          of %f32.
184    
185       3. Added a constructor INT32lit to the ast of MLRISC tools.

190    Tag: blume-20020116-ffifiddle
191    Description:
192    
193    More fiddling with the FFI interface:
194    
195     - Make constness 'c instead of rw wherever possible.  This eliminates
196       the need for certain explicit coercions.  (However, due to ML's
197       value polymorphism, there will still be many cases where explicit
198       coercions are necessary.  Phantom types are not the whole answer
199       to modeling a subtyping relationship in ML.)
200    
201     - ro/rw coersions for pointers added.  (Avoids the detour through */&.)
202    
203     - "printf" test example added to src/ml-nlffi-lib/Tests.  (Demonstrates
204       clumsy workaround for varargs problem.)

210    Description:
211    
212    1. Since COPY instructions are no longer native to the architecture,
213       a generic functor can be used to implement the expandCopies function.
214    
215    2. Allowed EXPORT and IMPORT pseudo-op declarations to appear inside a
216       TEXT segment.

221    Tag: blume-20020115-ffiupdates
222    Description:
223    
224    1. Fix for bug resulting in single-precision float values being returned
225       incorrectly from FFI calls.
226    
227    2. Small modifications to C FFI API:
228    
229        - memory-allocation routines return straight objects (no options)
230          and raise an exception in out-of-memory situations
231        - unsafe extensions to cast between function pointers and pointers
232          from/to ints
233        - added structure C_Debug as an alternative to structure C where
234          pointer-dereferencing (|*| and |*!) always check for null-pointers
235        - added open_lib' to DynLinkage;  open_lib' works like open_lib
236          but also takes a (possibly empty) list of existing library handles
237          that the current library depends on
238

243    Description:
244    
245    1. Updates to portable graph code.
246    
247    2. Major update to ml-nlffigen and ml-nlffi-lib.  Things are much
248       more scalable now so that even huge interfaces such as the one
249       for GTK compile in finite time and space. :-)
250       See src/ml-nlffigen/README for details on what's new.

255    Tag: george-20011206-rm-native-copy
256    Description:
257    
258            Removed the native COPY and FCOPY instructions
259            from all the architectures and replaced it with the
260            explicit COPY instruction from the previous commit.
261    
262            It is now possible to simplify many of the optimizations
263            modules that manipulate copies. This has not been
264            done in this change.
