19    Description:
20    
21    This update fixes a number of minor bugs in ml-nlffigen as reported by
22    Nick Carter <nbc@andrew.cmu.edu>.
23    
24      1. Silly but ok typedefs of the form "typedef void myvoid;" are now accepted.
25      2. Default names for generated files are now derived from the name of
26         the C file *without its directory*.  In particular, this causes generated
27         files to be placed locally even if the C file is in some system directory.
28      3. Default names for generated signatures and structures are also derived
29         from the C file name without its directory.  This avoids silly things
30         like "structure GL/GL".
31         (Other silly names are still possible because ml-nlffigen does not do
32          a thorough check of whether generated names are legal ML identifiers.
33          When in doubt, use command line arguments to force particular names.)

92    Description:
93    
94    Here is a short late-hour update related to Sparc c-calls:
95    
96     -- made handling of double-word arguments a bit smarter
97    
98     -- instruction selection phase tries to collapse certain clumsily
99        constructed ML-Trees; typical example:
100    
101            ADD(ty,ADD(_,e,LI d1),LI d2)  ->  ADD(ty,e,LI(d1+d2))
102    
103        This currently has no further impact on SML/NJ since mlriscGen does
104        not seem to generate such patterns in the first place, and c-calls
105        (which did generate them in the beginning) has meanwhile been fixed
106        so as to avoid them as well.

111    Tag: blume-20010615-sparc
112    Description:
113    
114    The purpose of this update is to provide an implementation of NLFFI
115    on Sparc machines.
116    
117    Here are the changes in detail:
118    
119       * src/MLRISC/sparc/c-calls/sparc-c-calls.sml is a new file containing
120       the Sparc implementation of the c-calls API.
121       * The Sparc backend of SML/NJ has been modified to uniformely use %fp
122       for accessing the ML frame.  Thus, we have a real frame pointer and
123       can freely modify %sp without need for an omit-frame-ptr phase.
124       The vfp logic in src/compiler/CodeGen/* has been changed to accomodate
125       this case.
126       * ml-nlffigen has been taught to produce code for different architectures
127       and calling conventions.
128       * In a way similar to what was done in the x86 case, the Sparc
129       backend uses its own specific extension to mltree.  (For example,
130       it needs to be able to generate UNIMP instructions which are part
131       of the calling convention.)
132       * ml-nlffi-lib was reorganized to make it more modular (in particular,
133       to make it easier to plug in new machine- and os-dependent parts).
134    
135    There are some other fairly unrelated bug fixes and cleanups as well:
136    
137       * I further hacked the .cm files for MLRISC tools (like MDLGen) so
138       that they properly share their libraries with existing SML/NJ libraries.
139       * I fixed a minor cosmetic bug in CM, supressing certain spurious
140       follow-up error messages.
141       * Updates to CM/CMB documentation.
142    
143    TODO items:
144    
145       * MLRISC should use a different register as its asmTemp on the Sparc.
146         (The current %o2 is a really bad choice because it is part of the
147         calling conventions, so things might interfere in unexpected ways.)

152    Tag: blume-20010607-calls
153    Description:
154    
155    A number of internal changes related to C calls and calling conventions:
156    
157    1. ML-Tree CALL statements now carry a "pops" field.  It indicates the
158       number of bytes popped implicitly (by the callee).  In most cases
159       this field is 0 but on x86/win32 it is some non-zero value.  This
160       is information provided for the benefit of the "omit-frameptr" pass.
161    2. The CALL instruction on the x86 carries a similar "pops" field.
162       The instruction selection phase copies its value from the ML-Tree
163       CALL statement.
164    3. On all other architectures, the instruction selection phase checks
165       whether "pops=0" and complains if not.
166    4. The c-calls implementation for x86 now accepts two calling conventions:
167       "ccall" and "stdcall".  When "ccall" is selected, the caller cleans
168       up after the call and pops is set to 0.  For "stdcall", the caller
169       does nothing, leaving the cleanup to the callee; pops is set to
170       the number of bytes that were pushed onto the stack.
171    5. The cproto decoder (compiler/Semant/types/cproto.sml) now can
172       distinguish between "ccall" and "stdcall".
173    6. The UNIMP instruction has been added to the supported Sparc instruction
174       set. (This is needed for implementing the official C calling convention
175       on this architecture.)
176    7. I fixed some of the .cm files under src/MLRISC/Tools to make them
177       work with the latest CM.

182    Tag: blume-20010605-cm-index
183    Description:
184    
185    0. The "lambdasplit" parameter for class "sml" in CM has been documented.
186    
187    1. CM can now generate "index files".  These are human-readable files
188       that list on a per-.cm-file basis each toplevel symbol defined or
189       imported.  The location of the index file for
190       <p>/<d>.cm is <p>/CM/INDEX/<d>.cm.
191       To enable index-file generation, set CM.Control.generate_index to true
192       or export an environment-symbol: export CM_GENERATE_INDEX=true.
193    
194       The CM manual has been updated accordingly.
195    
196    2. I made some slight modifications to the c-calls API in MLRISC.
197    
198         a) There is now a callback to support saving/restoring of
199            dedicated but caller-save registers around the actual call
200            instruction.
201         b) One can optionally specify a comment-annotation for the
202            call instruction.
203    
204    3. SML/NJ (mlriscGen.sml) uses this new API for the rawccall primop.
205       (For example, the comment annotation shows the C prototype of
206        the function being called.)

212    Description:
213    
214    This is mostly a cleanup of MLFFI stuff:
215    
216       - some signature files have been put into a more exposed place
217       - the ugly 'f type parameter is gone (simplifies types tremendously!)
218       - ml-nlffigen changed accordingly
219       - tutorial updated
220    
221    Other changes:
222    
223       - author's affiliation in CM manual(s) updated
224       - some more recognized keywords added to Allen's sml.sty

251    Description:
252    
253    Made install.sh use file config/targets.customized if it exists, falling
254    back to config/targets if it doesn't.  This way one can have a customized
255    version of the targets file without touching the "real thing", thus
256    eliminating the constant fear of accidentally checking something bogus
257    back into the CVS repository...  (File config/targets.customized must
258    not be added to the repository!)

277    Some bugs in install script fixed.
278    
279    In addition to that I also made a slight change to the NLFFI API:
280    Functors generated by ml-nlffigen now take the dynamic library as a
281    straight functor argument, not as a suspended one.  (The original
282    functor code used to force the suspension right away anyway, so there
283    was nothing gained by this complication of the interface.)

289    Description:
290    
291    I finally took the plunge and added my new FFI code to the main
292    repository.  For x86-linux it is now ready for prime-time.
293    
294    There are two new subdirectories of "src":
295    
296      - ml-nlffi-lib:
297           The utility library for programs using the FFI interface.
298           Here is the implementation of $/c.cm and its associated low-level
299           partners $/c-int.cm and $/memory.cm.
300      - ml-nlffigen:
301           A stand-alone program for generating ML glue code from C source
302           code.
303    
304    Building ml-nlffigen requires $/ckit-lib.cm.
305    
306    The config/install.sh script has been updates to do the Right Thing
307    (hopefully).
308    
309    Notice that the source tree for the C-Kit will not be put under "src"
310    but directly under the installation root directory.  (This is the
311    structure that currently exists on the CVS server when you check out
312    module "sml".)  Fortunately, config/install.sh knows about this oddity.
313    
314    Bugs: No documentation yet.

340    Tag: blume-20010507-proxies
341    Description:
342    
343    I made into "proxy libraries" all libraries that qualify for such a
344    change.  (A qualifying library is a library that has another library or
345    groups as its sole member and repeats that member's export list
346    verbatim.  A proxy library avoids this repetition by omitting its export
347    list, effectively inheriting the list that its (only) member exports.
348    See the CM manual for more explanation.)
349    The main effect is that explicit export lists for these libraries
350    do not have to be kepts in sync, making maintenance a bit easier.
351    
352    I also added copyright notices to many .cm-files.
353    
354    Last but not least, I made a new set of bootfiles.

360    Description:
361    
362    0. John merged pending changes to $/smlnj-lib.cm
363    
364    1. Allen's previous change accidentally backed out of one of Lal's
365       earlier changes.  I undid this mistake (re-introducing Lal's change).
366    
367    2. I used the new topOrder' function from graph-scc.sml (from $/smlnj-lib.cm)
368       within the compiler where applicable.  There is some code simplification
369       because of that.
370    
371    3. The "split" phase (in FLINT) is now part of the default list of phases.
372       Compiler.Control.LambdaSplitting.* can be used to globally control the
373       lambda-splitting (cross-module-inlining) engine.  In addition to that,
374       it can now also be controlled on a per-source basis: CM has been taught
375       a new tool parameter applicable to ML source files.
376    
377       - To turn lambda-splitting off completely:
378            local open Compiler.Control.LambdaSplitting in
379                val _ = set Off
380            end
381       - To make "no lambda-splitting" the global default (but allow per-source
382         overriding); this is the initial setting:
383            local open Compiler.Control.LambdaSplitting in
384                val _ = set (Default NONE)
385            end
386       - To make "lambda-splitting with aggressiveness a" the global default
387         (and allow per-source overriding):
388            local open Compiler.Control.LambdaSplitting in
389                val _ = set (Default (SOME a))
390            end
391    
392       - To turn lambda-splitting off for a given ML souce file (say: a.sml)
393         write (in the respective .cm-file):
394            a.sml (lambdasplitting:off)
395       - To turn lambda-splitting for a.sml on with minimal aggressiveness:
396            a.sml (lambdasplitting:on)
397       - To turn lambda-splitting for a.sml on with aggressiveness <a> (where
398         <a> is a decimal non-negative integer):
399            a.sml (lambdasplitting:<a>)
400       - To turn lambda-splitting for a.sml on with maximal aggressiveness:
401            a.sml (lambdasplitting:infinity)
402       - To use the global default for a.sml:
403            a.sml (lambdasplitting:default)
404         or simply
405            a.sml

463        passed correctly)
464     - changed the raw-C-call code in mlriscGen.sml in such a way that
465       structure arguments are represented as a pointer to the beginning
466       of the structure (instead of having a series of synthesized arguments,
467       one for each structure member)
468    
469     - made makeml script's verbosity level configurable via environment
470       variable (MAKEML_VERBOSITY)
471    
472     - eliminated placeholder implementations for f32l, w16s, i16s, and f32s
473       in rawmem-x86.sml; we are now using the real thing

497    Description:
498    
499    Parallel make (using compile servers) now works again.
500    
501    To this end, CM.stabilize and CMB.make have been modified to work in
502    two passes when compile servers are attached:
503       1. Compile everything, do not perform stabilization; this pass
504          uses compile servers
505       2. Stabilize everything; this pass does not use compile servers
506    If there are no compile servers, the two passes are combined into one
507    (as before).  Splitting the passes increases the inherent parallelism
508    in the dependency graph because the entire graph including all
509    libraries is available at the same time.  This, in turn, improves
510    server utilization.  The downside is that the master process will
511    have to do some extra work after compilation is done (because for
512    technical reasons it must re-read all the binfiles during stabilization).

626    Description:
627    
628    This is a fairly big patch, flushing out a large number of pending
629    changes that I made to my development copy over the last couple of days.
630    
631    Of practical relevance at this moment is a workaround for a pickling
632    bug that Allen ran into the other day.  The cause of the bug itself is
633    still unknown and it might be hard to fix it properly, but the
634    workaround has some merits of its own (namely somewhat reducing pickling
635    overhead for certain libraries).  Therefore, I think this solution should
636    be satisfactory at this time.
637    
638    The rest of the changes (i.e., the vast majority) has to do with my
639    ongoing efforts of providing direct support for C function calls from
640    ML.  At the moment there is a new primop "RAW_CCALL", typing magic
641    in types/cproto.sml (invoked from FLINT/trans/translate.sml), a new
642    case in the FLINT CPS datatype (RCC), changes to cps/convert.sml to
643    translate uses of RAW_CCALL into RCC, and changes to mlriscGen.sml to
644    handle RCC.
645    
646    The last part (the changes to mlriscGen.sml) are still known to be
647    wrong on the x86 and not implemented on all other architectures.  But
648    the infrastructure is in place. I had to change a few functor
649    signatures in the backend to be able to route the CCalls interface
650    from MLRISC there, and I had to specialize the mltree type (on the
651    x86) to include the necessary extensions. (The extensions themselves
652    were already there and redy to go in MLRISC/x86).
653    
654    Everything should be very happy as soon as someone helps me with
655    mlriscGen.sml...
656    
657    In any case, nothing of this should matter to anyone as long as the
658    new primop is not being used (which is going to be the case unless you
659    find it where I hid it :). The rest of the compiler is completely
660    unaffected.

666    Description:
667    
668    Added some experimental support for work that I am doing right now.
669    These changes mostly concern added primops, but there is also a new
670    experimental C library in the runtime system (but currently not enabled
671    anywhere except on Linux/X86).
672    
673    In the course of adding primops (and playing with them), I discovered that
674    Zhong's INL_PRIM hack (no type info for certain primops) was, in fact, badly
675    broken.  (Zhong was very right he labeled this stuff as "major gross hack".)
676    To recover, I made type information in INL_PRIM mandatory and changed
677    prim.sml as well as built-in.sml accordingly.  The InLine structure now
678    has complete, correct type information (i.e., no bottom types).
679    
680    Since all these changes mean that we need new binfiles, I also bumped the
681    version number to 110.32.1.
