19    Description:
20    
21     - added vp_limitPtrMask to vproc-state.h
22       (for use by the raw-C-calls mechanism to implement proper interrupt
23        handling)
24     - made the ML compiler aware of various data-structure offsets so it
25       can generate code for accessing the vp_inML flag and vp_limitPtrMask
26     - tweaked mlriscGen.sml to have it emit interrupt-handling code for
27       raw C-calls

44    Description:
45    
46     - fixed two off-by-4 errors in the x86-specific c-calls implementation
47       (this bug prevented structure arguments containing pointers from being
48        passed correctly)
49     - changed the raw-C-call code in mlriscGen.sml in such a way that
50       structure arguments are represented as a pointer to the beginning
51       of the structure (instead of having a series of synthesized arguments,
52       one for each structure member)
53    
54     - made makeml script's verbosity level configurable via environment
55       variable (MAKEML_VERBOSITY)
56    
57     - eliminated placeholder implementations for f32l, w16s, i16s, and f32s
58       in rawmem-x86.sml; we are now using the real thing

73    
74    1. All "raw memory access" primitives for the new FFI are implemented now
75       (at least on the x86).
76    2. Some further cleanup of CM's parallel make mechanism.

81    Tag: blume-20010319-parallel
82    Description:
83    
84    Parallel make (using compile servers) now works again.
85    
86    To this end, CM.stabilize and CMB.make have been modified to work in
87    two passes when compile servers are attached:
88       1. Compile everything, do not perform stabilization; this pass
89          uses compile servers
90       2. Stabilize everything; this pass does not use compile servers
91    If there are no compile servers, the two passes are combined into one
92    (as before).  Splitting the passes increases the inherent parallelism
93    in the dependency graph because the entire graph including all
94    libraries is available at the same time.  This, in turn, improves
95    server utilization.  The downside is that the master process will
96    have to do some extra work after compilation is done (because for
97    technical reasons it must re-read all the binfiles during stabilization).

129       New assembler flag "asm-show-cutsto" to turn on control-flow debugging.
130    
131    2. Register Allocator
132    
133       Changes in interface [from Fermin, John]

136    
137    4. All architectures
138    
139       A new module (ClusterExpandCopies) for expanding parallel copies.

172    Description:
173    
174    I am just flushing out some minor changes that had accumulated in
175    my private branch in order to sync with the main tree.  (This is
176    mainly because I had CVS trouble when trying to merge _into_ my
177    private branch.)
178    
179    Most people should be completely unaffected by this.

185    Description:
186    
187    1.  Removed the type LabelExp and replace it by MLTree.
188    2.  Rewritten mltree-simplify with the pattern matcher tool.
189    3.  There were some bugs in alpha code generator which would break
190        64-bit code generation.
191    4.  Redo the tools to generate code with the
192    5.  The CM files in MLRISC (and in src/system/smlnj/MLRISC)
193        are now generated by perl scripts.

199    Description:
200    
201    The RCC stuff now seems to work (but only on the x86).
202    This required hacking of the c-calls interface (and -implementation) in
203    MLRISC.
204    
205    Normal compiler users should be unaffected.

210    Tag: blume-20010109-rcc
211    Description:
212    
213    This is a fairly big patch, flushing out a large number of pending
214    changes that I made to my development copy over the last couple of days.
215    
216    Of practical relevance at this moment is a workaround for a pickling
217    bug that Allen ran into the other day.  The cause of the bug itself is
218    still unknown and it might be hard to fix it properly, but the
219    workaround has some merits of its own (namely somewhat reducing pickling
220    overhead for certain libraries).  Therefore, I think this solution should
221    be satisfactory at this time.
222    
223    The rest of the changes (i.e., the vast majority) has to do with my
224    ongoing efforts of providing direct support for C function calls from
225    ML.  At the moment there is a new primop "RAW_CCALL", typing magic
226    in types/cproto.sml (invoked from FLINT/trans/translate.sml), a new
227    case in the FLINT CPS datatype (RCC), changes to cps/convert.sml to
228    translate uses of RAW_CCALL into RCC, and changes to mlriscGen.sml to
229    handle RCC.
230    
231    The last part (the changes to mlriscGen.sml) are still known to be
232    wrong on the x86 and not implemented on all other architectures.  But
233    the infrastructure is in place. I had to change a few functor
234    signatures in the backend to be able to route the CCalls interface
235    from MLRISC there, and I had to specialize the mltree type (on the
236    x86) to include the necessary extensions. (The extensions themselves
237    were already there and redy to go in MLRISC/x86).
238    
239    Everything should be very happy as soon as someone helps me with
240    mlriscGen.sml...
241    
242    In any case, nothing of this should matter to anyone as long as the
243    new primop is not being used (which is going to be the case unless you
244    find it where I hid it :). The rest of the compiler is completely
245    unaffected.

250    Tag: blume-20010105-primops
251    Description:
252    
253    Added some experimental support for work that I am doing right now.
254    These changes mostly concern added primops, but there is also a new
255    experimental C library in the runtime system (but currently not enabled
256    anywhere except on Linux/X86).
257    
258    In the course of adding primops (and playing with them), I discovered that
259    Zhong's INL_PRIM hack (no type info for certain primops) was, in fact, badly
260    broken.  (Zhong was very right he labeled this stuff as "major gross hack".)
261    To recover, I made type information in INL_PRIM mandatory and changed
262    prim.sml as well as built-in.sml accordingly.  The InLine structure now
263    has complete, correct type information (i.e., no bottom types).
264    
265    Since all these changes mean that we need new binfiles, I also bumped the
266    version number to 110.32.1.

272    Description:
273    
274    Added proxy libraries for MLRISC and let MLRISC libraries refer
275    to each other using path anchors.  (See CM manual for explanation.)
276    
277    Updated CM documentation.
278    
279    Fixed some bugs in CM.
280    
281    Implemented "proxy" libraries (= syntactic sugar for CM).
282    
283    Added "-quiet" option to makeml and changed runtime system accordingly.
284    
285    Added cleanup handler for exportML to reset timers and compiler stats.

327    Probably most important: CM no longer silently swallows all exceptions
328    in the compiler.
329    Plus: some other minor CM changes.  For example, CM now reports some
330    sizes for generated binfiles (code, data, envpickle, lambdapickle).
