19    Description:
20    
21     - added vp_limitPtrMask to vproc-state.h
22       (for use by the raw-C-calls mechanism to implement proper interrupt
23        handling)
24     - made the ML compiler aware of various data-structure offsets so it
25       can generate code for accessing the vp_inML flag and vp_limitPtrMask
26     - tweaked mlriscGen.sml to have it emit interrupt-handling code for
27       raw C-calls

33    Description:
34    
35     - Changes to port to Mac OS X; Darwin.
36    
37     - In the process I found that sqrt was broken on the PPC, because the
38       fsqrt instruction is not implemented.

43    Tag: blume-20010418-ccalls
44    Description:
45    
46     - fixed two off-by-4 errors in the x86-specific c-calls implementation
47       (this bug prevented structure arguments containing pointers from being
48        passed correctly)
49     - changed the raw-C-call code in mlriscGen.sml in such a way that
50       structure arguments are represented as a pointer to the beginning
51       of the structure (instead of having a series of synthesized arguments,
52       one for each structure member)
53    
54     - made makeml script's verbosity level configurable via environment
55       variable (MAKEML_VERBOSITY)
56    
57     - eliminteded placeholder implementations for f32l, w16s, i16s, and f32s
58       in rawmem-x86.sml; we are now using the real thing

65    
66    Created a new set of bootfiles (for your automatic installation convenience).

72    Description:
73    
74    1. All "raw memory access" primitives for the new FFI are implemented now
75       (at least on the x86).
76    2. Some further cleanup of CM's parallel make mechanism.

82    Description:
83    
84    Parallel make (using compile servers) now works again.
85    
86    To this end, CM.stabilize and CMB.make have been modified to work in
87    two passes when compile servers are attached:
88       1. Compile everything, do not perform stabilization; this pass
89          uses compile servers
90       2. Stabilize everything; this pass does not use compile servers
91    If there are no compile servers, the two passes are combined into one
92    (as before).  Splitting the passes increases the inherent parallelism
93    in the dependency graph because the entire graph including all
94    libraries is available at the same time.  This, in turn, improves
95    server utilization.  The downside is that the master process will
96    have to do some extra work after compilation is done (because for
97    technical reasons it must re-read all the binfiles during stabilization).
