20    The RCC stuff now seems to work (but only on the x86).
21    This required hacking of the c-calls interface (and -implementation) in
22    MLRISC.
23    
24    Normal compiler users should be unaffected.

30    Description:
31    
32    This is a fairly big patch, flushing out a large number of pending
33    changes that I made to my development copy over the last couple of days.
34    
35    Of practical relevance at this moment is a workaround for a pickling
36    bug that Allen ran into the other day.  The cause of the bug itself is
37    still unknown and it might be hard to fix it properly, but the
38    workaround has some merits of its own (namely somewhat reducing pickling
39    overhead for certain libraries).  Therefore, I think this solution should
40    be satisfactory at this time.
41    
42    The rest of the changes (i.e., the vast majority) has to do with my
43    ongoing efforts of providing direct support for C function calls from
44    ML.  At the moment there is a new primop "RAW_CCALL", typing magic
45    in types/cproto.sml (invoked from FLINT/trans/translate.sml), a new
46    case in the FLINT CPS datatype (RCC), changes to cps/convert.sml to
47    translate uses of RAW_CCALL into RCC, and changes to mlriscGen.sml to
48    handle RCC.
49    
50    The last part (the changes to mlriscGen.sml) are still known to be
51    wrong on the x86 and not implemented on all other architectures.  But
52    the infrastructure is in place. I had to change a few functor
53    signatures in the backend to be able to route the CCalls interface
54    from MLRISC there, and I had to specialize the mltree type (on the
55    x86) to include the necessary extensions. (The extensions themselves
56    were already there and redy to go in MLRISC/x86).
57    
58    Everything should be very happy as soon as someone helps me with
59    mlriscGen.sml...
60    
61    In any case, nothing of this should matter to anyone as long as the
62    new primop is not being used (which is going to be the case unless you
63    find it where I hid it :). The rest of the compiler is completely
64    unaffected.

70    Description:
71    
72    Added some experimental support for work that I am doing right now.
73    These changes mostly concern added primops, but there is also a new
74    experimental C library in the runtime system (but currently not enabled
75    anywhere except on Linux/X86).
76    
77    In the course of adding primops (and playing with them), I discovered that
78    Zhong's INL_PRIM hack (no type info for certain primops) was, in fact, badly
79    broken.  (Zhong was very right he labeled this stuff as "major gross hack".)
80    To recover, I made type information in INL_PRIM mandatory and changed
81    prim.sml as well as built-in.sml accordingly.  The InLine structure now
82    has complete, correct type information (i.e., no bottom types).
83    
84    Since all these changes mean that we need new binfiles, I also bumped the
85    version number to 110.32.1.

91    Description:
92    
93    Added proxy libraries for MLRISC and let MLRISC libraries refer
94    to each other using path anchors.  (See CM manual for explanation.)
95    
96    Updated CM documentation.
97    
98    Fixed some bugs in CM.
99    
100    Implemented "proxy" libraries (= syntactic sugar for CM).
101    
102    Added "-quiet" option to makeml and changed runtime system accordingly.
103    
104    Added cleanup handler for exportML to reset timers and compiler stats.

119    Description:
120    
121    Corrected wording and formatting of some CM warning message which I
122    broke in my previous patch.

136    Description:
137    
138    Removed src/cm/ffi which does not (and did not) belong here.

144    Description:
145    
146    Probably most important: CM no longer silently swallows all exceptions
147    in the compiler.
148    Plus: some other minor CM changes.  For example, CM now reports some
149    sizes for generated binfiles (code, data, envpickle, lambdapickle).

165    Tag:  leunga-20001214-int-inf
166    Description:
167    
168       In IntInf, added these standard functions, which are missing from our
169    implementation:
170    
171        andb : int * int -> int
172        xorb : int * int -> int
173        orb  : int * int -> int
174        notb : int -> int
175         <<   : int * word -> int
176        ~>>  : int * word -> int
177    
178       Not tested, I hope they are correct.

187      Slight improvements to the 'nowhere' tool to handle OR-patterns,
188    to generate better error messages etc.  Plus a brief manual.
