18		Tag: blume-20010509-cpscontract
19		Description:
20
21		Fixed a bug in the accounting code in cpsopt/contract.sml.  (The
22		wrapper/unwrapper elimination did not decrement usage counts and some
23		dead variables got overlooked by the dead-up logic.)

29		Description:
30
31		Changes to implement the omit-frame-pointer optimization to support
32		raw C calls. For now, there is only support on the Intel x86, but
33		other architectures will follow as more experience is gained with this.

39		Tag: blume-20010507-proxies
40		Description:
41
42		I made into "proxy libraries" all libraries that qualify for such a
43		change.  (A qualifying library is a library that has another library or
44		groups as its sole member and repeats that member's export list
45		verbatim.  A proxy library avoids this repetition by omitting its export
46		list, effectively inheriting the list that its (only) member exports.
47		See the CM manual for more explanation.)
48		The main effect is that explicit export lists for these libraries
49		do not have to be kepts in sync, making maintenance a bit easier.
50
51		I also added copyright notices to many .cm-files.
52
53		Last but not least, I made a new set of bootfiles.

58		Tag: blume-20010504-cm-lsplit
59		Description:
60
61		0. John merged pending changes to $/smlnj-lib.cm
62
63		1. Allen's previous change accidentally backed out of one of Lal's
64		earlier changes.  I undid this mistake (re-introducing Lal's change).
65
66		2. I used the new topOrder' function from graph-scc.sml (from $/smlnj-lib.cm)
67		within the compiler where applicable.  There is some code simplification
68		because of that.
69
70		3. The "split" phase (in FLINT) is now part of the default list of phases.
71		Compiler.Control.LambdaSplitting.* can be used to globally control the
72		lambda-splitting (cross-module-inlining) engine.  In addition to that,
73		it can now also be controlled on a per-source basis: CM has been taught
74		a new tool parameter applicable to ML source files.
75
76		- To turn lambda-splitting off completely:
77		local open Compiler.Control.LambdaSplitting in
78		val _ = set Off
79		end
80		- To make "no lambda-splitting" the global default (but allow per-source
81		overriding); this is the initial setting:
82		local open Compiler.Control.LambdaSplitting in
83		val _ = set (Default NONE)
84		end
85		- To make "lambda-splitting with aggressiveness a" the global default
86		(and allow per-source overriding):
87		local open Compiler.Control.LambdaSplitting in
88		val _ = set (Default (SOME a))
89		end
90
91		- To turn lambda-splitting off for a given ML souce file (say: a.sml)
92		write (in the respective .cm-file):
93		a.sml (lambdasplitting:off)
94		- To turn lambda-splitting for a.sml on with minimal aggressiveness:
95		a.sml (lambdasplitting:on)
96		- To turn lambda-splitting for a.sml on with aggressiveness <a> (where
97		<a> is a decimal non-negative integer):
98		a.sml (lambdasplitting:<a>)
99		- To turn lambda-splitting for a.sml on with maximal aggressiveness:
100		a.sml (lambdasplitting:infinity)
101		- To use the global default for a.sml:
102		a.sml (lambdasplitting:default)
103		or simply
104		a.sml

109		Tag: leunga-20010504-sync
110		Description:
111
112		MLRISC features.
113
114		1. Fix to CMPXCHG instructions.
115		2. Changed RA interface to allow annotations in callbacks.
116		3. Added a new method to the stream interface to allow annotations updates.

119		Name: Matthias Blume
120		Date: 2001/05/01 11:45:00 EDT
121		Tag: blume-20010501-pcedittmp
122		Description:
123
124		Changed install.sh to use the current working directory instead of
125		/usr/tmp for a temporary file (pcedittmp).  The previous choice
126		of /usr/tmp caused trouble with MacOS X because of file premission
127		problems.

131		Date: 2001/04/20 11:10:00 EDT
132		Tag: blume-20010420-inMLflag
133		Description:
134
135		- added vp_limitPtrMask to vproc-state.h
136		(for use by the raw-C-calls mechanism to implement proper interrupt
137		handling)
138		- made the ML compiler aware of various data-structure offsets so it
139		can generate code for accessing the vp_inML flag and vp_limitPtrMask
140		- tweaked mlriscGen.sml to have it emit interrupt-handling code for
141		raw C-calls

146		Tag: george-20010420-macosX
147		Description:
148
149		- Changes to port to Mac OS X; Darwin.
150
151		- In the process I found that sqrt was broken on the PPC, because the
152		fsqrt instruction is not implemented.

156		Date: 2001/04/18 12:45:00 EDT
157		Tag: blume-20010418-ccalls
158		Description:
159
160		- fixed two off-by-4 errors in the x86-specific c-calls implementation
161		(this bug prevented structure arguments containing pointers from being
162		passed correctly)
163		- changed the raw-C-call code in mlriscGen.sml in such a way that
164		structure arguments are represented as a pointer to the beginning
165		of the structure (instead of having a series of synthesized arguments,
166		one for each structure member)
167
168		- made makeml script's verbosity level configurable via environment
169		variable (MAKEML_VERBOSITY)
170
171		- eliminated placeholder implementations for f32l, w16s, i16s, and f32s
172		in rawmem-x86.sml; we are now using the real thing

185		Tag: blume-20010322-rawmem-parcm
186		Description:
187
188		1. All "raw memory access" primitives for the new FFI are implemented now
189		(at least on the x86).
190		2. Some further cleanup of CM's parallel make mechanism.

195		Tag: blume-20010319-parallel
196		Description:
197
198		Parallel make (using compile servers) now works again.
199
200		To this end, CM.stabilize and CMB.make have been modified to work in
201		two passes when compile servers are attached:
202		1. Compile everything, do not perform stabilization; this pass
203		uses compile servers
204		2. Stabilize everything; this pass does not use compile servers
205		If there are no compile servers, the two passes are combined into one
206		(as before).  Splitting the passes increases the inherent parallelism
207		in the dependency graph because the entire graph including all
208		libraries is available at the same time.  This, in turn, improves
209		server utilization.  The downside is that the master process will
210		have to do some extra work after compilation is done (because for
211		technical reasons it must re-read all the binfiles during stabilization).

226
227		This is a minor fixup for an (untagged) earlier commit by Allen.
228		(A file was missing).

233		Tag: leunga-20010305-cut-support
234
235		1. New support for alternative control-flow in MLTREE.
236		Currently we support
237
238		FLOW_TO(CALL ...., [k1,...,kn])
239
240		This is needed for 'cuts to' in C-- and try/handle-like constructs
241		in Moby
242
243		New assembler flag "asm-show-cutsto" to turn on control-flow debugging.
244
245		2. Register Allocator
246
247		Changes in interface [from Fermin, John]
248
249		3. Alpha 8-bit SLL support [Fermin]
250
251		4. All architectures
252
253		A new module (ClusterExpandCopies) for expanding parallel copies.
