19    Description:
20    
21    1. Bug fix in ml-nlffigen; now (hopefully) correctly handling
22       struct returns.
23    2. Added src/ml-nlffi-lib/Doc/mini-tutorial.txt.  This is some very
24       incomplete, preliminary documentation for NLFFI.

30    Description:
31    
32    Some bugs in install script fixed.
33    
34    In addition to that I also made a slight change to the NLFFI API:
35    Functors generated by ml-nlffigen now take the dynamic library as a
36    straight functor argument, not as a suspended one.  (The original
37    functor code used to force the suspension right away anyway, so there
38    was nothing gained by this complication of the interface.)

43    Tag: blume-20010511-ml-nlffi
44    Description:
45    
46    I finally took the plunge and added my new FFI code to the main
47    repository.  For x86-linux it is now ready for prime-time.
48    
49    There are two new subdirectories of "src":
50    
51      - ml-nlffi-lib:
52           The utility library for programs using the FFI interface.
53           Here is the implementation of $/c.cm and its associated low-level
54           partners $/c-int.cm and $/memory.cm.
55      - ml-nlffigen:
56           A stand-alone program for generating ML glue code from C source
57           code.
58    
59    Building ml-nlffigen requires $/ckit-lib.cm.
60    
61    The config/install.sh script has been updates to do the Right Thing
62    (hopefully).
63    
64    Notice that the source tree for the C-Kit will not be put under "src"
65    but directly under the installation root directory.  (This is the
66    structure that currently exists on the CVS server when you check out
67    module "sml".)  Fortunately, config/install.sh knows about this oddity.
68    
69    Bugs: No documentation yet.

74    Tag: blume-20010509-cpscontract
75    Description:
76    
77    Fixed a bug in the accounting code in cpsopt/contract.sml.  (The
78    wrapper/unwrapper elimination did not decrement usage counts and some
79    dead variables got overlooked by the dead-up logic.)

84    Tag: george-20010508-omit-frameptr
85    Description:
86    
87    Changes to implement the omit-frame-pointer optimization to support
88    raw C calls. For now, there is only support on the Intel x86, but
89    other architectures will follow as more experience is gained with this.

95    Tag: blume-20010507-proxies
96    Description:
97    
98    I made into "proxy libraries" all libraries that qualify for such a
99    change.  (A qualifying library is a library that has another library or
100    groups as its sole member and repeats that member's export list
101    verbatim.  A proxy library avoids this repetition by omitting its export
102    list, effectively inheriting the list that its (only) member exports.
103    See the CM manual for more explanation.)
104    The main effect is that explicit export lists for these libraries
105    do not have to be kepts in sync, making maintenance a bit easier.
106    
107    I also added copyright notices to many .cm-files.
108    
109    Last but not least, I made a new set of bootfiles.

114    Tag: blume-20010504-cm-lsplit
115    Description:
116    
117    0. John merged pending changes to $/smlnj-lib.cm
118    
119    1. Allen's previous change accidentally backed out of one of Lal's
120       earlier changes.  I undid this mistake (re-introducing Lal's change).
121    
122    2. I used the new topOrder' function from graph-scc.sml (from $/smlnj-lib.cm)
123       within the compiler where applicable.  There is some code simplification
124       because of that.
125    
126    3. The "split" phase (in FLINT) is now part of the default list of phases.
127       Compiler.Control.LambdaSplitting.* can be used to globally control the
128       lambda-splitting (cross-module-inlining) engine.  In addition to that,
129       it can now also be controlled on a per-source basis: CM has been taught
130       a new tool parameter applicable to ML source files.
131    
132       - To turn lambda-splitting off completely:
133            local open Compiler.Control.LambdaSplitting in
134                val _ = set Off
135            end
136       - To make "no lambda-splitting" the global default (but allow per-source
137         overriding); this is the initial setting:
138            local open Compiler.Control.LambdaSplitting in
139                val _ = set (Default NONE)
140            end
141       - To make "lambda-splitting with aggressiveness a" the global default
142         (and allow per-source overriding):
143            local open Compiler.Control.LambdaSplitting in
144                val _ = set (Default (SOME a))
145            end
146    
147       - To turn lambda-splitting off for a given ML souce file (say: a.sml)
148         write (in the respective .cm-file):
149            a.sml (lambdasplitting:off)
150       - To turn lambda-splitting for a.sml on with minimal aggressiveness:
151            a.sml (lambdasplitting:on)
152       - To turn lambda-splitting for a.sml on with aggressiveness <a> (where
153         <a> is a decimal non-negative integer):
154            a.sml (lambdasplitting:<a>)
155       - To turn lambda-splitting for a.sml on with maximal aggressiveness:
156            a.sml (lambdasplitting:infinity)
157       - To use the global default for a.sml:
158            a.sml (lambdasplitting:default)
159         or simply
160            a.sml

166    Description:
167    
168      MLRISC features.
169    
170      1. Fix to CMPXCHG instructions.
171      2. Changed RA interface to allow annotations in callbacks.
172      3. Added a new method to the stream interface to allow annotations updates.

177    Tag: blume-20010501-pcedittmp
178    Description:
179    
180    Changed install.sh to use the current working directory instead of
181    /usr/tmp for a temporary file (pcedittmp).  The previous choice
182    of /usr/tmp caused trouble with MacOS X because of file premission
183    problems.

188    Tag: blume-20010420-inMLflag
189    Description:
190    
191     - added vp_limitPtrMask to vproc-state.h
192       (for use by the raw-C-calls mechanism to implement proper interrupt
193        handling)
194     - made the ML compiler aware of various data-structure offsets so it
195       can generate code for accessing the vp_inML flag and vp_limitPtrMask
196     - tweaked mlriscGen.sml to have it emit interrupt-handling code for
197       raw C-calls

203    Description:
204    
205     - Changes to port to Mac OS X; Darwin.
206    
207     - In the process I found that sqrt was broken on the PPC, because the
208       fsqrt instruction is not implemented.

213    Tag: blume-20010418-ccalls
214    Description:
215    
216     - fixed two off-by-4 errors in the x86-specific c-calls implementation
217       (this bug prevented structure arguments containing pointers from being
218        passed correctly)
219     - changed the raw-C-call code in mlriscGen.sml in such a way that
220       structure arguments are represented as a pointer to the beginning
221       of the structure (instead of having a series of synthesized arguments,
222       one for each structure member)
223    
224     - made makeml script's verbosity level configurable via environment
225       variable (MAKEML_VERBOSITY)
226    
227     - eliminated placeholder implementations for f32l, w16s, i16s, and f32s
228       in rawmem-x86.sml; we are now using the real thing

242    Description:
243    
244    1. All "raw memory access" primitives for the new FFI are implemented now
245       (at least on the x86).
246    2. Some further cleanup of CM's parallel make mechanism.
