19    Description:
20    
21    Changed install.sh to use the current working directory instead of
22    /usr/tmp for a temporary file (pcedittmp).  The previous choice
23    of /usr/tmp caused trouble with MacOS X because of file premission
24    problems.

31    
32     - added vp_limitPtrMask to vproc-state.h
33       (for use by the raw-C-calls mechanism to implement proper interrupt
34        handling)
35     - made the ML compiler aware of various data-structure offsets so it
36       can generate code for accessing the vp_inML flag and vp_limitPtrMask
37     - tweaked mlriscGen.sml to have it emit interrupt-handling code for
38       raw C-calls

48     - In the process I found that sqrt was broken on the PPC, because the

55    Description:
56    
57     - fixed two off-by-4 errors in the x86-specific c-calls implementation
58       (this bug prevented structure arguments containing pointers from being
59        passed correctly)
60     - changed the raw-C-call code in mlriscGen.sml in such a way that
61       structure arguments are represented as a pointer to the beginning
62       of the structure (instead of having a series of synthesized arguments,
63       one for each structure member)
64    
65     - made makeml script's verbosity level configurable via environment
66       variable (MAKEML_VERBOSITY)
67    
68     - eliminated placeholder implementations for f32l, w16s, i16s, and f32s
69       in rawmem-x86.sml; we are now using the real thing

84    
85    1. All "raw memory access" primitives for the new FFI are implemented now
86       (at least on the x86).
87    2. Some further cleanup of CM's parallel make mechanism.

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

130    Tag: leunga-20010305-cut-support
131    
132    1. New support for alternative control-flow in MLTREE.
133       Currently we support
134    
135          FLOW_TO(CALL ...., [k1,...,kn])
136    
137       This is needed for 'cuts to' in C-- and try/handle-like constructs
138       in Moby
139    
140       New assembler flag "asm-show-cutsto" to turn on control-flow debugging.
141    
142    2. Register Allocator
143    
144       Changes in interface [from Fermin, John]
145    
146    3. Alpha 8-bit SLL support [Fermin]
147    
148    4. All architectures
149    
150       A new module (ClusterExpandCopies) for expanding parallel copies.

183    Description:
184    
185    I am just flushing out some minor changes that had accumulated in
186    my private branch in order to sync with the main tree.  (This is
187    mainly because I had CVS trouble when trying to merge _into_ my
188    private branch.)
189    
190    Most people should be completely unaffected by this.

196    Description:
197    
198    1.  Removed the type LabelExp and replace it by MLTree.
199    2.  Rewritten mltree-simplify with the pattern matcher tool.
200    3.  There were some bugs in alpha code generator which would break
201        64-bit code generation.
202    4.  Redo the tools to generate code with the
203    5.  The CM files in MLRISC (and in src/system/smlnj/MLRISC)
204        are now generated by perl scripts.

210    Description:
211    
212    The RCC stuff now seems to work (but only on the x86).
213    This required hacking of the c-calls interface (and -implementation) in
214    MLRISC.
215    
216    Normal compiler users should be unaffected.

221    Tag: blume-20010109-rcc
222    Description:
223    
224    This is a fairly big patch, flushing out a large number of pending
225    changes that I made to my development copy over the last couple of days.
226    
227    Of practical relevance at this moment is a workaround for a pickling
228    bug that Allen ran into the other day.  The cause of the bug itself is
229    still unknown and it might be hard to fix it properly, but the
230    workaround has some merits of its own (namely somewhat reducing pickling
231    overhead for certain libraries).  Therefore, I think this solution should
232    be satisfactory at this time.
233    
234    The rest of the changes (i.e., the vast majority) has to do with my
235    ongoing efforts of providing direct support for C function calls from
236    ML.  At the moment there is a new primop "RAW_CCALL", typing magic
237    in types/cproto.sml (invoked from FLINT/trans/translate.sml), a new
238    case in the FLINT CPS datatype (RCC), changes to cps/convert.sml to
239    translate uses of RAW_CCALL into RCC, and changes to mlriscGen.sml to
240    handle RCC.
241    
242    The last part (the changes to mlriscGen.sml) are still known to be
243    wrong on the x86 and not implemented on all other architectures.  But
244    the infrastructure is in place. I had to change a few functor
245    signatures in the backend to be able to route the CCalls interface
246    from MLRISC there, and I had to specialize the mltree type (on the
247    x86) to include the necessary extensions. (The extensions themselves
248    were already there and redy to go in MLRISC/x86).
249    
250    Everything should be very happy as soon as someone helps me with
251    mlriscGen.sml...
252    
253    In any case, nothing of this should matter to anyone as long as the
254    new primop is not being used (which is going to be the case unless you
255    find it where I hid it :). The rest of the compiler is completely
256    unaffected.

261    Tag: blume-20010105-primops
262    Description:
263    
264    Added some experimental support for work that I am doing right now.
265    These changes mostly concern added primops, but there is also a new
266    experimental C library in the runtime system (but currently not enabled
267    anywhere except on Linux/X86).
268    
269    In the course of adding primops (and playing with them), I discovered that
270    Zhong's INL_PRIM hack (no type info for certain primops) was, in fact, badly
271    broken.  (Zhong was very right he labeled this stuff as "major gross hack".)
272    To recover, I made type information in INL_PRIM mandatory and changed
273    prim.sml as well as built-in.sml accordingly.  The InLine structure now
274    has complete, correct type information (i.e., no bottom types).
275    
276    Since all these changes mean that we need new binfiles, I also bumped the
277    version number to 110.32.1.

283    Description:
284    
285    Added proxy libraries for MLRISC and let MLRISC libraries refer
286    to each other using path anchors.  (See CM manual for explanation.)
287    
288    Updated CM documentation.
289    
290    Fixed some bugs in CM.
291    
292    Implemented "proxy" libraries (= syntactic sugar for CM).
293    
294    Added "-quiet" option to makeml and changed runtime system accordingly.
295    
296    Added cleanup handler for exportML to reset timers and compiler stats.

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