18    Description:
19    
20    0. John merged pending changes to $/smlnj-lib.cm
21    
22    1. Allen's previous change accidentally backed out of one of Lal's
23       earlier changes.  I undid this mistake (re-introducing Lal's change).
24    
25    2. I used the new topOrder' function from graph-scc.sml (from $/smlnj-lib.cm)
26       within the compiler where applicable.  There is some code simplification
27       because of that.
28    
29    3. The "split" phase (in FLINT) is now part of the default list of phases.
30       Compiler.Control.LambdaSplitting.* can be used to globally control the
31       lambda-splitting (cross-module-inlining) engine.  In addition to that,
32       it can now also be controlled on a per-source basis: CM has been taught
33       a new tool parameter applicable to ML source files.
34    
35       - To turn lambda-splitting off completely:
36            local open Compiler.Control.LambdaSplitting in
37                val _ = set Off
38            end
39       - To make "no lambda-splitting" the global default (but allow per-source
40         overriding); this is the initial setting:
41            local open Compiler.Control.LambdaSplitting in
42                val _ = set (Default NONE)
43            end
44       - To make "lambda-splitting with aggressiveness a" the global default
45         (and allow per-source overriding):
46            local open Compiler.Control.LambdaSplitting in
47                val _ = set (Default (SOME a))
48            end
49    
50       - To turn lambda-splitting off for a given ML souce file (say: a.sml)
51         write (in the respective .cm-file):
52            a.sml (lambdasplitting:off)
53       - To turn lambda-splitting for a.sml on with minimal aggressiveness:
54            a.sml (lambdasplitting:on)
55       - To turn lambda-splitting for a.sml on with aggressiveness <a> (where
56         <a> is a decimal non-negative integer):
57            a.sml (lambdasplitting:<a>)
58       - To turn lambda-splitting for a.sml on with maximal aggressiveness:
59            a.sml (lambdasplitting:infinity)
60       - To use the global default for a.sml:
61            a.sml (lambdasplitting:default)
62         or simply
63            a.sml

70    
71      MLRISC features.
72    
73      1. Fix to CMPXCHG instructions.
74      2. Changed RA interface to allow annotations in callbacks.
75      3. Added a new method to the stream interface to allow annotations updates.

81    Description:
82    
83    Changed install.sh to use the current working directory instead of
84    /usr/tmp for a temporary file (pcedittmp).  The previous choice
85    of /usr/tmp caused trouble with MacOS X because of file premission
86    problems.

91    Tag: blume-20010420-inMLflag
92    Description:
93    
94     - added vp_limitPtrMask to vproc-state.h
95       (for use by the raw-C-calls mechanism to implement proper interrupt
96        handling)
97     - made the ML compiler aware of various data-structure offsets so it
98       can generate code for accessing the vp_inML flag and vp_limitPtrMask
99     - tweaked mlriscGen.sml to have it emit interrupt-handling code for
100       raw C-calls

106    Description:
107    
108     - Changes to port to Mac OS X; Darwin.
109    
110     - In the process I found that sqrt was broken on the PPC, because the
111       fsqrt instruction is not implemented.

116    Tag: blume-20010418-ccalls
117    Description:
118    
119     - fixed two off-by-4 errors in the x86-specific c-calls implementation
120       (this bug prevented structure arguments containing pointers from being
121        passed correctly)
122     - changed the raw-C-call code in mlriscGen.sml in such a way that
123       structure arguments are represented as a pointer to the beginning
124       of the structure (instead of having a series of synthesized arguments,
125       one for each structure member)
126    
127     - made makeml script's verbosity level configurable via environment
128       variable (MAKEML_VERBOSITY)
129    
130     - eliminated placeholder implementations for f32l, w16s, i16s, and f32s
131       in rawmem-x86.sml; we are now using the real thing

144    Tag: blume-20010322-rawmem-parcm
145    Description:
146    
147    1. All "raw memory access" primitives for the new FFI are implemented now
148       (at least on the x86).
149    2. Some further cleanup of CM's parallel make mechanism.

154    Tag: blume-20010319-parallel
155    Description:
156    
157    Parallel make (using compile servers) now works again.
158    
159    To this end, CM.stabilize and CMB.make have been modified to work in
160    two passes when compile servers are attached:
161       1. Compile everything, do not perform stabilization; this pass
162          uses compile servers
163       2. Stabilize everything; this pass does not use compile servers
164    If there are no compile servers, the two passes are combined into one
165    (as before).  Splitting the passes increases the inherent parallelism
166    in the dependency graph because the entire graph including all
167    libraries is available at the same time.  This, in turn, improves
168    server utilization.  The downside is that the master process will
169    have to do some extra work after compilation is done (because for
170    technical reasons it must re-read all the binfiles during stabilization).
