27    Description:
28    
29    Made install.sh use file config/targets.customized if it exists, falling
30    back to config/targets if it doesn't.  This way one can have a customized
31    version of the targets file without touching the "real thing", thus
32    eliminating the constant fear of accidentally checking something bogus
33    back into the CVS repository...  (File config/targets.customized must
34    not be added to the repository!)

40    Description:
41    
42    1. Bug fix in ml-nlffigen; now (hopefully) correctly handling
43       struct returns.
44    2. Added src/ml-nlffi-lib/Doc/mini-tutorial.txt.  This is some very
45       incomplete, preliminary documentation for NLFFI.

51    Description:
52    
53    Some bugs in install script fixed.
54    
55    In addition to that I also made a slight change to the NLFFI API:
56    Functors generated by ml-nlffigen now take the dynamic library as a
57    straight functor argument, not as a suspended one.  (The original
58    functor code used to force the suspension right away anyway, so there
59    was nothing gained by this complication of the interface.)

64    Tag: blume-20010511-ml-nlffi
65    Description:
66    
67    I finally took the plunge and added my new FFI code to the main
68    repository.  For x86-linux it is now ready for prime-time.
69    
70    There are two new subdirectories of "src":
71    
72      - ml-nlffi-lib:
73           The utility library for programs using the FFI interface.
74           Here is the implementation of $/c.cm and its associated low-level
75           partners $/c-int.cm and $/memory.cm.
76      - ml-nlffigen:
77           A stand-alone program for generating ML glue code from C source
78           code.
79    
80    Building ml-nlffigen requires $/ckit-lib.cm.
81    
82    The config/install.sh script has been updates to do the Right Thing
83    (hopefully).
84    
85    Notice that the source tree for the C-Kit will not be put under "src"
86    but directly under the installation root directory.  (This is the
87    structure that currently exists on the CVS server when you check out
88    module "sml".)  Fortunately, config/install.sh knows about this oddity.
89    
90    Bugs: No documentation yet.

95    Tag: blume-20010509-cpscontract
96    Description:
97    
98    Fixed a bug in the accounting code in cpsopt/contract.sml.  (The
99    wrapper/unwrapper elimination did not decrement usage counts and some
100    dead variables got overlooked by the dead-up logic.)

105    Tag: george-20010508-omit-frameptr
106    Description:
107    
108    Changes to implement the omit-frame-pointer optimization to support
109    raw C calls. For now, there is only support on the Intel x86, but
110    other architectures will follow as more experience is gained with this.

116    Tag: blume-20010507-proxies
117    Description:
118    
119    I made into "proxy libraries" all libraries that qualify for such a
120    change.  (A qualifying library is a library that has another library or
121    groups as its sole member and repeats that member's export list
122    verbatim.  A proxy library avoids this repetition by omitting its export
123    list, effectively inheriting the list that its (only) member exports.
124    See the CM manual for more explanation.)
125    The main effect is that explicit export lists for these libraries
126    do not have to be kepts in sync, making maintenance a bit easier.
127    
128    I also added copyright notices to many .cm-files.
129    
130    Last but not least, I made a new set of bootfiles.

135    Tag: blume-20010504-cm-lsplit
136    Description:
137    
138    0. John merged pending changes to $/smlnj-lib.cm
139    
140    1. Allen's previous change accidentally backed out of one of Lal's
141       earlier changes.  I undid this mistake (re-introducing Lal's change).
142    
143    2. I used the new topOrder' function from graph-scc.sml (from $/smlnj-lib.cm)
144       within the compiler where applicable.  There is some code simplification
145       because of that.
146    
147    3. The "split" phase (in FLINT) is now part of the default list of phases.
148       Compiler.Control.LambdaSplitting.* can be used to globally control the
149       lambda-splitting (cross-module-inlining) engine.  In addition to that,
150       it can now also be controlled on a per-source basis: CM has been taught
151       a new tool parameter applicable to ML source files.
152    
153       - To turn lambda-splitting off completely:
154            local open Compiler.Control.LambdaSplitting in
155                val _ = set Off
156            end
157       - To make "no lambda-splitting" the global default (but allow per-source
158         overriding); this is the initial setting:
159            local open Compiler.Control.LambdaSplitting in
160                val _ = set (Default NONE)
161            end
162       - To make "lambda-splitting with aggressiveness a" the global default
163         (and allow per-source overriding):
164            local open Compiler.Control.LambdaSplitting in
165                val _ = set (Default (SOME a))
166            end
167    
168       - To turn lambda-splitting off for a given ML souce file (say: a.sml)
169         write (in the respective .cm-file):
170            a.sml (lambdasplitting:off)
171       - To turn lambda-splitting for a.sml on with minimal aggressiveness:
172            a.sml (lambdasplitting:on)
173       - To turn lambda-splitting for a.sml on with aggressiveness <a> (where
174         <a> is a decimal non-negative integer):
175            a.sml (lambdasplitting:<a>)
176       - To turn lambda-splitting for a.sml on with maximal aggressiveness:
177            a.sml (lambdasplitting:infinity)
178       - To use the global default for a.sml:
179            a.sml (lambdasplitting:default)
180         or simply
181            a.sml

187    Description:
188    
189      MLRISC features.
190    
191      1. Fix to CMPXCHG instructions.
192      2. Changed RA interface to allow annotations in callbacks.
193      3. Added a new method to the stream interface to allow annotations updates.

198    Tag: blume-20010501-pcedittmp
199    Description:
200    
201    Changed install.sh to use the current working directory instead of
202    /usr/tmp for a temporary file (pcedittmp).  The previous choice
203    of /usr/tmp caused trouble with MacOS X because of file premission
204    problems.

209    Tag: blume-20010420-inMLflag
210    Description:
211    
212     - added vp_limitPtrMask to vproc-state.h
213       (for use by the raw-C-calls mechanism to implement proper interrupt
214        handling)
215     - made the ML compiler aware of various data-structure offsets so it
216       can generate code for accessing the vp_inML flag and vp_limitPtrMask
217     - tweaked mlriscGen.sml to have it emit interrupt-handling code for
218       raw C-calls

224    Description:
225    
226     - Changes to port to Mac OS X; Darwin.
227    
228     - In the process I found that sqrt was broken on the PPC, because the
229       fsqrt instruction is not implemented.

234    Tag: blume-20010418-ccalls
235    Description:
236    
237     - fixed two off-by-4 errors in the x86-specific c-calls implementation
238       (this bug prevented structure arguments containing pointers from being
239        passed correctly)
240     - changed the raw-C-call code in mlriscGen.sml in such a way that
241       structure arguments are represented as a pointer to the beginning
242       of the structure (instead of having a series of synthesized arguments,
243       one for each structure member)
244    
245     - made makeml script's verbosity level configurable via environment
246       variable (MAKEML_VERBOSITY)
247    
248     - eliminated placeholder implementations for f32l, w16s, i16s, and f32s
249       in rawmem-x86.sml; we are now using the real thing

263    Description:
264    
265    1. All "raw memory access" primitives for the new FFI are implemented now
266       (at least on the x86).
267    2. Some further cleanup of CM's parallel make mechanism.
