Added EnvRef.listBoundSymbols and CM.State.showBindings. Especially |
51 |
|
the latter can be useful for exploring what bindings are available at |
52 |
|
the interactive prompt. (The first function returns only the list |
53 |
|
of symbols that are really bound, the second prints those but also the |
54 |
|
ones that CM's autoloading mechanism knows about.) |

Two improvements to ml-nlffigen: |
63 |
|
|
64 |
|
1. Write files only if they do not exist or if their current contents |
65 |
|
do not coincide with what's being written. (That is, avoid messing |
66 |
|
with the time stamps unless absolutely necessary.) |
67 |
|
|
68 |
|
2. Implement a "repository" mechanism for generated files related |
69 |
|
to "incomplete pointer types". See the README file for details. |

Fixed the MLRISC bug sent by Markus Wenzel regarding the compilation |
88 |
|
of Isabelle on the x86. |
89 |
|
|
90 |
|
From Allen: |
91 |
|
----------- |
92 |
|
I've found the problem: |
93 |
|
|
94 |
|
in ra-core.sml, I use the counter "blocked" to keep track of the |
95 |
|
true number of elements in the freeze queue. When the counter goes |
96 |
|
to zero, I skip examining the queue. But I've messed up the |
97 |
|
bookkeeping in combine(): |
98 |
|
|
99 |
|
else (); |
100 |
|
case !ucol of |
101 |
|
PSEUDO => (if !cntv > 0 then |
102 |
|
(if !cntu > 0 then blocked := !blocked - 1 else (); |
103 |
|
^^^^^^^^^^^^^^^^^^^^^^^ |
104 |
|
moveu := mergeMoveList(!movev, !moveu) |
105 |
|
) |
106 |
|
else (); |
107 |
|
|
108 |
|
combine() is called to coalesce two nodes u and v. |
109 |
|
I think I was thinking that if the move counts of u and v are both |
110 |
|
greater than zero then after they are coalesced then one node is |
111 |
|
removed from the freeze queue. Apparently I was thinking that |
112 |
|
both u and v are of low degree, but that's clearly not necessarily true. |
113 |
|
|
114 |
|
|
115 |
|
02/12/2002: |
116 |
|
Here's the patch. HOL now compiles. |
117 |
|
|
118 |
|
I don't know how this impact on performance (compile |
119 |
|
time or runtime). This bug caused the RA (especially on the x86) |
120 |
|
to go thru the potential spill phase when there are still nodes on the |
121 |
|
freeze queue. |

1. More tweaks to ml-nlffigen: |
152 |
|
|
153 |
|
- better internal datastructures (resulting in slight speedup) |
154 |
|
- "-match" option requires exact match |
155 |
|
- "localized" gensym counters (untagged structs/unions nested within |
156 |
|
other structs/unions or within typedefs get a fresh counter; their |
157 |
|
tag will be prefixed by a concatenation of their parents' tags) |
158 |
|
- bug fixes (related to calculation of transitive closure of types |
159 |
|
to be included in the output) |
160 |
|
|
161 |
|
2. Minor Basis updates: |
162 |
|
|
163 |
|
- added implementations for List.collate and Option.app |

Added a "-gensym" option to command line of ml-nlffigen. This can be |
172 |
|
used to specify a "stem" -- a string that is inserted in all "gensym'd" |
173 |
|
names (ML structure names that correspond to unnamed C structs, unions, |
174 |
|
and enums), so that separate runs of ml-nlffigen do not clash. |

|
A quick fix for a problem with GenSML (in the pgraph-util library): |
183 |
|
Make generation of toplevel "local" optional. (Strictly speaking, |
184 |
|
signature definitions within "local" are not legal SML.) |
185 |
|
|
186 |

Other than that: updates to INSTALL and cm/TODO. |

0. Version number has been bumped to 110.38.1. NEW BOOTFILES!!! |
195 |
|
|
196 |
|
1. The installer (config/install.sh) has gotten smarter: |
197 |
|
|
198 |
|
- Configuration options are a bit easier to specify now |
199 |
|
(in config/targets). |
200 |
|
- Bug in recognizing .tar.bz2 files fixed. |
201 |
|
- Installer automatically resolves dependencies between |
202 |
|
configuration options (e.g., if you ask for eXene, you will |
203 |
|
also get cml -- regardless whether you asked for it or not). |
204 |
|
- Installer can run in "quieter mode" by setting the environment |
205 |
|
variable INSTALL_QUIETLY to "true". "Quieter" does not mean |
206 |
|
"completely silent", though. |
207 |
|
- Build HashCons library as part of smlnj-lib. |
208 |
|
|
209 |
|
2. A new scheme for assigning persistent identifiers to compilation |
210 |
|
units (and, by extension, to types etc.) has been put into place. |
211 |
|
This fixes a long-standing bug where types and even dynamic values |
212 |
|
can get internally confused, thereby compromising type safety |
213 |
|
(abstraction) and dynamic correctness. See |
214 |
|
|
215 |
|
http://cm.bell-labs.com/cm/cs/who/blume/pid-confusion.tgz |
216 |
|
|
217 |
|
for an example of how things could go wrong until now. |
218 |
|
|
219 |
|
The downside of the new scheme is that pids are not quite as |
220 |
|
persistent as they used to be: CM will generate a fresh pid |
221 |
|
for every compilation unit that it thinks it sees for the first |
222 |
|
time. That means that if you compile starting from a clean, fresh |
223 |
|
source tree at two different times, you end up with different |
224 |
|
binaries. |
225 |
|
|
226 |
|
Cutoff recompilation, however, has not been compromised because |
227 |
|
CM keeps pid information in special caches between runs. |

Compilers that generate assembly code may produce global labels |

|
modules did not take this in account. |
238 |

239 |

TODO. The Labels.addrOf function should really return an option |
240 |

type so that clients are forced to deal with this issue, rather |
241 |
|
than an exception being raised. |

1. A bug fix from Allen. |
250 |
|
|
251 |
|
A typo causes extra fstp %st(0)'s to be generated at compensation |
252 |
|
edges, which might cause stack underflow traps at runtime. This |
253 |
|
occurs in fft where there are extraneous fstps right before the 'into' |
254 |
|
trap instruction (in this case they are harmless since none of the |
255 |
|
integers overflow.) |
256 |
|
|
257 |
|
2. Pulled out various utility modules that were embedded in the modules |
258 |
|
of the register allocator. I need these modules for other purposes, but |
259 |
|
they are not complete enough to put into a library (just yet). |

Another day of fiddling with the FFI... |
408 |
|
|
409 |
|
1. Bug fix/workaround: CKIT does not complain about negative array |
410 |
|
dimensions, so ml-nlffigen has to guard itself against this possibility. |
411 |
|
(Otherwise a negative dimension would send it into an infinite loop.) |
412 |
|
|
413 |
|
2. Some of the abstract types (light objects, light pointers, most "base" |
414 |
|
types) in structure C are now eqtypes. |
415 |
|
|
416 |
|
3. Added constructors and test functions for NULL function pointers. |

Today's FFI fiddling: |
436 |
|
|
437 |
|
- Provided a structure CGetSet with "convenient" versions of C.Get.* and |
438 |
|
C.Set.* that use concrete (MLRep.*) arguments and results instead |
439 |
|
of abstract ones. |
440 |
|
|
441 |
|
- Provided word-style bit operations etc. for "int" representation |
442 |
|
types in MLRep.S<Foo>Bitops where <Foo> ranges over Char, Int, Short, |
443 |
|
and Long. |

More fiddling with the FFI interface: |
479 |
|
|
480 |
|
- Make constness 'c instead of rw wherever possible. This eliminates |
481 |
|
the need for certain explicit coercions. (However, due to ML's |
482 |
|
value polymorphism, there will still be many cases where explicit |
483 |
|
coercions are necessary. Phantom types are not the whole answer |
484 |
|
to modeling a subtyping relationship in ML.) |
485 |
|
|
486 |
|
- ro/rw coersions for pointers added. (Avoids the detour through */&.) |
487 |
|
|
488 |
|
- "printf" test example added to src/ml-nlffi-lib/Tests. (Demonstrates |
489 |
|
clumsy workaround for varargs problem.) |

2. Small modifications to C FFI API: |
513 |
|
|
514 |
|
- memory-allocation routines return straight objects (no options) |
515 |
|
and raise an exception in out-of-memory situations |
516 |
|
- unsafe extensions to cast between function pointers and pointers |
517 |
|
from/to ints |
518 |
|
- added structure C_Debug as an alternative to structure C where |
519 |
|
pointer-dereferencing (|*| and |*!) always check for null-pointers |
520 |
|
- added open_lib' to DynLinkage; open_lib' works like open_lib |
521 |
|
but also takes a (possibly empty) list of existing library handles |
522 |
|
that the current library depends on |

|
Description: |
556 |
|
|
557 |
|
Changed the representation of instructions from being fully abstract |
558 |
|
to being partially concrete. That is to say: |
559 |
|
|
560 |
|
from |
561 |
|
type instruction |
562 |
|
|
563 |
|
to |
564 |
|
type instr (* machine instruction *) |
565 |
|
|
566 |
|
datatype instruction = |
567 |
|
LIVE of {regs: C.cellset, spilled: C.cellset} |
568 |
|
| KILL of {regs: C.cellset, spilled: C.cellset} |
569 |
|
| COPYXXX of {k: CB.cellkind, dst: CB.cell list, src: CB.cell list} |
570 |
|
| ANNOTATION of {i: instruction, a: Annotations.annotation} |
571 |
|
| INSTR of instr |
572 |
|
|
573 |
|
This makes the handling of certain special instructions that appear on |
574 |
|
all architectures easier and uniform. |
575 |
|
|
576 |
|
LIVE and KILL say that a list of registers are live or killed at the |
577 |
|
program point where they appear. No spill code is generated when an |
578 |
|
element of the 'regs' field is spilled, but the register is moved to |
579 |
|
the 'spilled' (which is present, more for debugging than anything else). |
580 |
|
|
581 |
|
LIVE replaces the (now deprecated) DEFFREG instruction on the alpha. |
582 |
|
We used to generate: |
583 |
|
|
584 |
|
DEFFREG f1 |
585 |
|
f1 := f2 + f3 |
586 |
|
trapb |
587 |
|
|
588 |
|
but now generate: |
589 |
|
|
590 |
|
f1 := f2 + f3 |
591 |
|
trapb |
592 |
|
LIVE {regs=[f1,f2,f3], spilled=[]} |
593 |
|
|
594 |
|
Furthermore, the DEFFREG (hack) required that all floating point instruction |
595 |
|
use all registers mentioned in the instruction. Therefore f1 := f2 + f3, |
596 |
|
defines f1 and uses [f1,f2,f3]! This hack is no longer required resulting |
597 |
|
in a cleaner alpha implementation. (Hopefully, intel will not get rid of |
598 |
|
this architecture). |
599 |
|
|
600 |
|
COPYXXX is intended to replace the parallel COPY and FCOPY available on |
601 |
|
all the architectures. This will result in further simplification of the |
602 |
|
register allocator that must be aware of them for coalescing purposes, and |
603 |
|
will also simplify certain aspects of the machine description that provides |
604 |
|
callbacks related to parallel copies. |
605 |
|
|
606 |
|
ANNOTATION should be obvious, and now INSTR represents the honest to God |
607 |
|
machine instruction set! |
608 |
|
|
609 |
|
The <arch>/instructions/<arch>Instr.sml files define certain utility |
610 |
|
functions for making porting easier -- essentially converting upper case |
611 |
|
to lower case. All machine instructions (of type instr) are in upper case, |
612 |
|
and the lower case form generates an MLRISC instruction. For example on |
613 |
|
the alpha we have: |
614 |
|
|
615 |
|
datatype instr = |
616 |
|
LDA of {r:cell, b:cell, d:operand} |
617 |
|
| ... |
618 |
|
|
619 |
|
val lda : {r:cell, b:cell, d:operand} -> instruction |
620 |
|
... |
621 |
|
|
622 |
|
where lda is just (INSTR o LDA), etc. |

|
1. Modifications to the SML/NJ code generator and to the runtime system |
661 |
|
so that code object name strings are directly inserted into code |
662 |
|
objects at code generation time. The only business the runtime system |
663 |
|
has with this is now to read the name strings on occasions. |
664 |
|
(The encoding of the name string has also changed somewhat.) |
665 |
|
|
666 |
|
2. CM now implements a simple "set calculus" for specifying export lists. |
667 |
|
In particular, it is now possible to refer to the export lists of |
668 |
|
other libraries/groups/sources and form unions as well as differences. |
669 |
|
See the latest CM manual for details. |
670 |
|
|
671 |
|
3. An separate notion of "proxy" libraries has again be eliminated from |
672 |
|
CM's model. (Proxy libraries are now simply a special case of using |
673 |
|
the export list calculus.) |
674 |
|
|
675 |
|
4. Some of the existing libraries now take advantage of the new set |
676 |
|
calculus. |
677 |
|
(Notice that not all libraries have been converted because some |
678 |
|
of the existing .cm-files are supposed to be backward compatible |
679 |
|
with 110.0.x.) |
680 |
|
|
681 |
|
5. Some cleanup in stand-alone programs. (Don't use "exnMessage" -- use |
682 |
|
"General.exnMessage"! The former relies on a certain hook to be |
683 |
|
initialized, and that often does not happen in the stand-alone case.) |

Fix for a backpatching bug reported by Allen. |
720 |
|
|
721 |
|
Because the boundary between short and long span-dependent |
722 |
|
instructions is +/- 128, there are an astounding number of |
723 |
|
span-dependent instructions whose size is over estimated. |
724 |
|
|
725 |
|
Allen came up with the idea of letting the size of span |
726 |
|
dependent instructions be non-monotonic, for a maxIter |
727 |
|
number of times, after which the size must be monotonically |
728 |
|
increasing. |
729 |
|
|
730 |
|
This table shows the number of span-dependent instructions |
731 |
|
whose size was over-estimated as a function of maxIter, for the |
732 |
|
file Parse/parse/ml.grm.sml: |
733 |
|
|
734 |
|
maxIter # of instructions: |
735 |
|
10 687 |
736 |
|
20 438 |
737 |
|
30 198 |
738 |
|
40 0 |
739 |
|
|
740 |
|
In compiling the compiler, there is no significant difference in |
741 |
|
compilation speed between maxIter=10 and maxIter=40. Actually, |
742 |
|
my measurements showed that maxIter=40 was a tad faster than |
743 |
|
maxIter=10! Also 96% of the files in the compiler reach a fix |
744 |
|
point within 13 iterations, so fixing maxIter at 40, while high, |
745 |
|
is okay. |

|
Description: |
837 |
|
|
838 |
|
I provided a non-hook implementation of exnName (at the toplevel) and |
839 |
|
made the "dummy" implementation of exnMessage (at the toplevel) more |
840 |
|
useful: if nothing gets "hooked in", then at least you are going to |
841 |
|
see the exception name and a message indicating why you don't see more. |
842 |
|
|
843 |
|
[For the time being, programs that need exnMessage and want to use |
844 |
|
ml-build should either use General.exnMessage (strongly recommended) or |
845 |
|
refer to structure General at some other point so that CM sees a |
846 |
|
static dependency.] |
847 |
|
|
848 |
|
[Similar remarks go for "print" and "use": If you want to use their |
849 |
|
functionality in stand-alone programs generated by ml-build, then use |
850 |
|
TextIO.output and Backend.Interact.useFile (from $smlnj/compiler.cm).] |

0. Updated the BOOT file (something that I forgot to do earlier). |
867 |
|
|
868 |
|
1. Small internal change to CM so that it avoids "/../" in filenames |
869 |
|
as much as possible (but only where it is safe). |
870 |
|
|
871 |
|
2. Changed config/_run-sml (resulting in a changed bin/.run-sml) so |
872 |
|
that arguments that contain delimiters are passed through correctly. |
873 |
|
This change also means that all "special" arguments of the form |
874 |
|
@SMLxxx... must come first. |
875 |
|
|
876 |
|
3. Changed install script to put relative anchor names for tool commands |
877 |
|
into pathconfig. |

John committed some changes that Allen made, in particular a (hopefully) |
910 |
|
correctly working version of the x86-fp module. |
911 |
|
|
912 |
|
I changed the default setting of the Control.MLRISC.getFlag "x86-fast-fp" |
913 |
|
flag to "true". Everything seems to compile to a fixpoint ok, and |
914 |
|
"mandelbrot" speeds up by about 15%. |

1. Stefan Monnier's patch to fix a miscompilation problem that |
923 |
|
was brought to light by John Reppy's work on Moby. |
924 |
|
|
925 |
|
2. Implemented a minimal "structure Compiler" that contains just |
926 |
|
"version" and "architecture". The minimal version will be |
927 |
|
available when the full version is not. This is for backward- |
928 |
|
compatibility with code that wants to test Compiler.version. |
