19    Description:
20    
21    Added a "-gensym" option to command line of ml-nlffigen.  This can be
22    used to specify a "stem" -- a string that is inserted in all "gensym'd"
23    names (ML structure names that correspond to unnamed C structs, unions,
24    and enums), so that separate runs of ml-nlffigen do not clash.

30    Description:
31    
32    A quick fix for a problem with GenSML (in the pgraph-util library):
33    Make generation of toplevel "local" optional.  (Strictly speaking,
34    signature definitions within "local" are not legal SML.)
35    
36    Other than that: updates to INSTALL and cm/TODO.

42    Description:
43    
44    0. Version number has been bumped to 110.38.1.  NEW BOOTFILES!!!
45    
46    1. The installer (config/install.sh) has gotten smarter:
47    
48         - Configuration options are a bit easier to specify now
49           (in config/targets).
50         - Bug in recognizing .tar.bz2 files fixed.
51         - Installer automatically resolves dependencies between
52           configuration options (e.g., if you ask for eXene, you will
53           also get cml -- regardless whether you asked for it or not).
54         - Installer can run in "quieter mode" by setting the environment
55           variable INSTALL_QUIETLY to "true".  "Quieter" does not mean
56           "completely silent", though.
57         - Build HashCons library as part of smlnj-lib.
58    
59    2. A new scheme for assigning persistent identifiers to compilation
60       units (and, by extension, to types etc.) has been put into place.
61       This fixes a long-standing bug where types and even dynamic values
62       can get internally confused, thereby compromising type safety
63       (abstraction) and dynamic correctness.  See
64    
65         http://cm.bell-labs.com/cm/cs/who/blume/pid-confusion.tgz
66    
67       for an example of how things could go wrong until now.
68    
69       The downside of the new scheme is that pids are not quite as
70       persistent as they used to be: CM will generate a fresh pid
71       for every compilation unit that it thinks it sees for the first
72       time.  That means that if you compile starting from a clean, fresh
73       source tree at two different times, you end up with different
74       binaries.
75    
76       Cutoff recompilation, however, has not been compromised because
77       CM keeps pid information in special caches between runs.

83    Description:
84    
85    Compilers that generate assembly code may produce  global labels
86    whose value is resolved at link time. The various peephole optimization
87    modules did not take this in account.
88    
89    TODO. The Labels.addrOf function should really return an option
90    type so that clients are forced to deal with this issue, rather
91    than an exception being raised.

97    Description:
98    
99    1. A bug fix from Allen.
100    
101        A typo causes extra fstp %st(0)'s to be generated at compensation
102        edges, which might cause stack underflow traps at runtime.  This
103        occurs in fft where there are extraneous fstps right before the 'into'
104        trap instruction (in this case they are harmless since none of the
105        integers overflow.)
106    
107    2. Pulled out various utility modules that were embedded in the modules
108       of the register allocator. I need these modules for other purposes, but
109       they are not complete enough to put into a library (just yet).

114    Description:
115    
116    1. C-calls on Sparc needlessly allocated a huge chunk (96 bytes)
117       of extra stack space by mistake.  Fixed.
118    
119    2. Bug in logic of handling of command-line options in ml-nlffigen fixed.

126    
127       MLRISC bug fixes:
128       1. Fixed a bindings computation bug in the 'nowhere' program generator tool.
129       2. MachineInt.fromString was negating its value.

134    Tag: blume-20020129-INSTALL
135    Description:
136    
137    - Added somewhat detailed installation instructions (file INSTALL).
138    - Fixed curl-detection bug in config/install.sh.
139    - It is now possible to select the URL getter using the URLGETTER
140      environment variable:
141    
142          not set / "unknown"      --> automatic detection (script tries wget,
143                                       curl, and lynx)
144          "wget" / "curl" / "lynx" --> use the specified program (script "knows"
145                                       how to properly invoke them)
146          other                    --> use $URLGETTER directly, it must take
147                                       precisely two command-line arguments
148                                       (source URL and destination file name)

155    
156    - Fixed problem with calculation of "used" registers in sparc-c-calls.
157    - Make use of the allocParam argument in sparc-c-calls.

166    allocating extra stack space.
167    me: Corresponding changes to mlriscGen (using a dummy argument that
168        does not change the current behavior).

182    Description:
183    
184    0. Retracted earlier 110.38.  (The Release_110_38 tag has been replaced
185       with blume-Release_110_38-retracted.)
186    
187    1. Fixed a problem with incorrect rounding modes in real64.sml.
188       (Thanks to Andrew Mccreight <andrew.mccreight@yale.edu>.)
189    
190    2. A bug in ml-nlffigen related to the handling of unnamed structs, unions,
191       and enums fixed.  The naming of corresponding ML identifiers should
192       now be consistent again.

198    Description:
199    
200       Added a target called nowhere in the configuration scripts.
201       Enabling this will build the MLRISC 'nowhere' tool (for translating
202       programs with where-clauses into legal SML code) during installation.

210    Call it a (working) release!  Version is 110.38. Bootfiles are ready.
211    
212    README will be added later.
213    
214    !!! NOTE:  Re-tagged as blume-Release_110_38-retracted. Original tag
215    (Release_110_38) removed.  Reason: Last-minute bug fixes.

220    Tag: blume-20020125-ffi
221    Description:
222    
223    A large number of tweaks and improvements to ml-nlffi-lib and
224    ml-nlffigen:
225    
226       - ML represenation types have been streamlined
227       - getter and setter functions work with concrete values, not abstract
228         ones where possible
229       - ml-nlffigen command line more flexible (see README file there)
230       - some bugs have been fixed (hopefully)

236    Description:
237    
238       There is a dramatic simplification in the interface to the
239       register allocator for RISC architectures as a result of making
240       parallel copy instructions explicit.

247    
248    Bug fix for c-calls on x86 (having to do with how char- and
249    short-arguments are being handled).

255    Description:
256    
257    Another day of fiddling with the FFI...
258    
259    1. Bug fix/workaround:  CKIT does not complain about negative array
260       dimensions, so ml-nlffigen has to guard itself against this possibility.
261       (Otherwise a negative dimension would send it into an infinite loop.)
262    
263    2. Some of the abstract types (light objects, light pointers, most "base"
264       types) in structure C are now eqtypes.
265    
266    3. Added constructors and test functions for NULL function pointers.

274    Made config/srcarchiveurl point to a new place.  (Will provide boot
275    files shortly.)
276    
277    Maybe we christen this to be 110.38?

283    Description:
284    
285    Today's FFI fiddling:
286    
287      - Provided a structure CGetSet with "convenient" versions of C.Get.* and
288        C.Set.* that use concrete (MLRep.*) arguments and results instead
289        of abstract ones.
290    
291      - Provided word-style bit operations etc. for "int" representation
292        types in MLRep.S<Foo>Bitops where <Foo> ranges over Char, Int, Short,
293        and Long.

299    Description:
300    
301    Now that x86-fast-fp seems to be working, I turned it back on again
302    by default.  (Seems to work fine now, even with the FFI.)
303    
304    Other than that, I added some documentation about the FFI to
305    src/ml-nlffigen/README and updated the FFI test examples in
306    src/ml-nlffi-lib/Tests/*.
