21     - Changes to port to Mac OS X; Darwin.
22    
23     - In the process I found that sqrt was broken on the PPC, because the
24       fsqrt instruction is not implemented.

30    Description:
31    
32     - fixed two off-by-4 errors in the x86-specific c-calls implementation
33       (this bug prevented structure arguments containing pointers from being
34        passed correctly)
35     - changed the raw-C-call code in mlriscGen.sml in such a way that
36       structure arguments are represented as a pointer to the beginning
37       of the structure (instead of having a series of synthesized arguments,
38       one for each structure member)
39    
40     - made makeml script's verbosity level configurable via environment
41       variable (MAKEML_VERBOSITY)
42    
43     - eliminteded placeholder implementations for f32l, w16s, i16s, and f32s
44       in rawmem-x86.sml; we are now using the real thing

59    
60    1. All "raw memory access" primitives for the new FFI are implemented now
61       (at least on the x86).
62    2. Some further cleanup of CM's parallel make mechanism.

68    Description:
69    
70    Parallel make (using compile servers) now works again.
71    
72    To this end, CM.stabilize and CMB.make have been modified to work in
73    two passes when compile servers are attached:
74       1. Compile everything, do not perform stabilization; this pass
75          uses compile servers
76       2. Stabilize everything; this pass does not use compile servers
77    If there are no compile servers, the two passes are combined into one
78    (as before).  Splitting the passes increases the inherent parallelism
79    in the dependency graph because the entire graph including all
80    libraries is available at the same time.  This, in turn, improves
81    server utilization.  The downside is that the master process will
82    have to do some extra work after compilation is done (because for
83    technical reasons it must re-read all the binfiles during stabilization).

105    Tag: leunga-20010305-cut-support
106    
107    1. New support for alternative control-flow in MLTREE.
108       Currently we support
109    
110          FLOW_TO(CALL ...., [k1,...,kn])
111    
112       This is needed for 'cuts to' in C-- and try/handle-like constructs
113       in Moby
114    
115       New assembler flag "asm-show-cutsto" to turn on control-flow debugging.
116    
117    2. Register Allocator
118    
119       Changes in interface [from Fermin, John]
120    
121    3. Alpha 8-bit SLL support [Fermin]
122    
123    4. All architectures
124    
125       A new module (ClusterExpandCopies) for expanding parallel copies.

158    Description:
159    
160    I am just flushing out some minor changes that had accumulated in
161    my private branch in order to sync with the main tree.  (This is
162    mainly because I had CVS trouble when trying to merge _into_ my
163    private branch.)
164    
165    Most people should be completely unaffected by this.

171    Description:
172    
173    1.  Removed the type LabelExp and replace it by MLTree.
174    2.  Rewritten mltree-simplify with the pattern matcher tool.
175    3.  There were some bugs in alpha code generator which would break
176        64-bit code generation.
177    4.  Redo the tools to generate code with the
178    5.  The CM files in MLRISC (and in src/system/smlnj/MLRISC)
179        are now generated by perl scripts.

185    Description:
186    
187    The RCC stuff now seems to work (but only on the x86).
188    This required hacking of the c-calls interface (and -implementation) in
189    MLRISC.
190    
191    Normal compiler users should be unaffected.

196    Tag: blume-20010109-rcc
197    Description:
198    
199    This is a fairly big patch, flushing out a large number of pending
200    changes that I made to my development copy over the last couple of days.
201    
202    Of practical relevance at this moment is a workaround for a pickling
203    bug that Allen ran into the other day.  The cause of the bug itself is
204    still unknown and it might be hard to fix it properly, but the
205    workaround has some merits of its own (namely somewhat reducing pickling
206    overhead for certain libraries).  Therefore, I think this solution should
207    be satisfactory at this time.
208    
209    The rest of the changes (i.e., the vast majority) has to do with my
210    ongoing efforts of providing direct support for C function calls from
211    ML.  At the moment there is a new primop "RAW_CCALL", typing magic
212    in types/cproto.sml (invoked from FLINT/trans/translate.sml), a new
213    case in the FLINT CPS datatype (RCC), changes to cps/convert.sml to
214    translate uses of RAW_CCALL into RCC, and changes to mlriscGen.sml to
215    handle RCC.
216    
217    The last part (the changes to mlriscGen.sml) are still known to be
218    wrong on the x86 and not implemented on all other architectures.  But
219    the infrastructure is in place. I had to change a few functor
220    signatures in the backend to be able to route the CCalls interface
221    from MLRISC there, and I had to specialize the mltree type (on the
222    x86) to include the necessary extensions. (The extensions themselves
223    were already there and redy to go in MLRISC/x86).
224    
225    Everything should be very happy as soon as someone helps me with
226    mlriscGen.sml...
227    
228    In any case, nothing of this should matter to anyone as long as the
229    new primop is not being used (which is going to be the case unless you
230    find it where I hid it :). The rest of the compiler is completely
231    unaffected.

236    Tag: blume-20010105-primops
237    Description:
238    
239    Added some experimental support for work that I am doing right now.
240    These changes mostly concern added primops, but there is also a new
241    experimental C library in the runtime system (but currently not enabled
242    anywhere except on Linux/X86).
243    
244    In the course of adding primops (and playing with them), I discovered that
245    Zhong's INL_PRIM hack (no type info for certain primops) was, in fact, badly
246    broken.  (Zhong was very right he labeled this stuff as "major gross hack".)
247    To recover, I made type information in INL_PRIM mandatory and changed
248    prim.sml as well as built-in.sml accordingly.  The InLine structure now
249    has complete, correct type information (i.e., no bottom types).
250    
251    Since all these changes mean that we need new binfiles, I also bumped the
252    version number to 110.32.1.

258    Description:
259    
260    Added proxy libraries for MLRISC and let MLRISC libraries refer
261    to each other using path anchors.  (See CM manual for explanation.)
262    
263    Updated CM documentation.
264    
265    Fixed some bugs in CM.
266    
267    Implemented "proxy" libraries (= syntactic sugar for CM).
268    
269    Added "-quiet" option to makeml and changed runtime system accordingly.
270    
271    Added cleanup handler for exportML to reset timers and compiler stats.

312    
313    Probably most important: CM no longer silently swallows all exceptions
314    in the compiler.
315    Plus: some other minor CM changes.  For example, CM now reports some
316    sizes for generated binfiles (code, data, envpickle, lambdapickle).
