1. Alpha |
| 29 |
|
|
| 30 |
|
Slight cleanup. Removed the instruction SGNXL |
| 31 |
|
|
| 32 |
|
2. X86 |
| 33 |
|
|
| 34 |
|
Added the following instructions to the instruction set: |
| 35 |
|
|
| 36 |
|
ROLx, RORx, |
| 37 |
|
BTx, BTSx, BTLx, BTRx, |
| 38 |
|
XCHGx, and variants with the LOCK prefix |
| 39 |
|
|

|
3. Register Allocation |

|
The module ra-rewrite-with-renaming has been improved. |
| 43 |
|
|
| 44 |

Description: |

1. I added an alternative to "-rebuild" to "makeml". The difference is |
| 53 |
|
that prior to calling CMB.make' the CM-variable "LIGHT" will be |
| 54 |
|
defined. In effect, the command will not build any cross-compiler |
| 55 |
|
backends and therefore finish more quickly. |
| 56 |
|
|
| 57 |
|
The "fixpt" script also takes a "-light" switch to be able to use |
| 58 |
|
this new facility while compiling for a fixpoint. |
| 59 |
|
|
| 60 |
|
2. I replaced all mentions of anchored paths in group owner specifications |
| 61 |
|
with simple relative paths (usually starting with ".."). |
| 62 |
|
The rationale is that a library's internal workings should not be |
| 63 |
|
compromised by the lack of some anchor. (An anchor is necessary |
| 64 |
|
for someone who wants to refer to the library by an anchored path, |
| 65 |
|
but it should not be necessary to build the same library in the first |
| 66 |
|
place.) |
| 67 |
|
|
| 68 |
|
3. I changed the way CM's tool mechanism determines the shell command |
| 69 |
|
string used for things like ml-yacc etc. so that it does not break |
| 70 |
|
when CM.Control.implicit_anchors is turned off. |

!!! NEW BOOT FILES !!! |
| 88 |
|
|
| 89 |
|
This change is in preparation of fading out support for "implicitly |
| 90 |
|
anchored path names". I went through all sources and used the |
| 91 |
|
explicit (and relatively new) $-notation. See system/README and the |
| 92 |
|
CM manual for more info on this. |
| 93 |
|
|
| 94 |
|
I also modified the anchoring scheme for some things such as "smlnj", |
| 95 |
|
"MLRISC", "cm", etc. to take advantage of the fact that explicit |
| 96 |
|
anchors are more expressive: anchor name and first arc do not have to |
| 97 |
|
coincide. This entails the following user-visible change: |
| 98 |
|
|
| 99 |
|
You have to write $smlnj/foo/bar instead of smlnj/foo/bar. In |
| 100 |
|
particular, when you fire up sml with a command-line argument, say, |
| 101 |
|
e.g.: |
| 102 |
|
|
| 103 |
|
sml '$smlnj/cmb.cm' |
| 104 |
|
|
| 105 |
|
At the ML toplevel prompt: |
| 106 |
|
|
| 107 |
|
CM.autoload "$smlnj/cmb.cm"; |
| 108 |
|
|
| 109 |
|
There is also a new controller in CM.Control that can be used to turn |
| 110 |
|
off all remaining support for implicit anchors by saying: |
| 111 |
|
|
| 112 |
|
CM.autoload "$smlnj/ |
| 113 |
|
#set CM.Control.implicit_anchors false; |
| 114 |
|
|
| 115 |
|
This causes CM to reject implicitly anchored paths. This is (for the |
| 116 |
|
time being) less permissive than the "final" version where there will |
| 117 |
|
be no more such implicit anchors and relative paths will be just that: |
| 118 |
|
relative. |
| 119 |
|
|
| 120 |
|
The next step (version after next version?) will be to make the |
| 121 |
|
default for CM.Control.implicit_anchors false. After the dust has |
| 122 |
|
settled, I can then produce the "final" version of this... |
| 123 |
|
|
| 124 |
|
Note: Since bootstrapping is a bit tricky, I provided new boot files. |

The main change is that I added function CM.sources as a generalized |

additional changes: |
| 135 |
|

- CM.makedepend has been dropped. |
| 137 |
|
|

1. Register Allocation |
| 152 |
|
|
| 153 |
|
a. A new ra spilling module (ra/ra-spill-with-renaming) is implemented. |
| 154 |
|
This module tries to remove local (i.e. basic block level) redundancies |
| 155 |
|
during spilling. |
| 156 |
|
|
| 157 |
|
b. A new framework for performing region based register allocation. |
| 158 |
|
Not yet entirely functional. |
| 159 |
|

2. X86 |
| 161 |
|
|
| 162 |
|
a. DefUse for POP was missing the stack pointer [found by Lal] |
| 163 |
|
b. Reload for CALL was incorrect in X86Spill [found by John] |
| 164 |
|
c. Various fixes in X86Spill so that it can be used correctly for |
| 165 |
|
the new spilling module. |
| 166 |
|
|
| 167 |
|
3. SSA/IR |

Fermin has found a few assembly problems with constant expressions |

| 243 |
|
Description: |
| 244 |
|
|
| 245 |
|
1. CM version numbering added. This is an implementation of Lal's |
| 246 |
|
proposal for adding version numbers and version checking to .cm |
| 247 |
|
files. Lal said that his proposal was just that -- a proposal. |
| 248 |
|
For the time being I went ahead and implemented it so that people |
| 249 |
|
can comment on it. Everything is completely backward-compatible |
| 250 |
|
(except for the stable library format, i.e., new bootfiles!). |
| 251 |
|
|
| 252 |
|
As usual, see the CM manual for details. |
| 253 |
|
|
| 254 |
|
2. An alternative syntax for anchored paths has been implemented. |
| 255 |
|
Dave has recently voiced the same concerns that I had when I did |
| 256 |
|
this, so there should be some support. My take is that eventually |
| 257 |
|
I will let support for the current syntax (where anchors are |
| 258 |
|
"implicit") fade out in favor of the new, explicit syntax. |
| 259 |
|
In order to be backward-compatible, both old and new syntax are |
| 260 |
|
currently supported. |
| 261 |
|
|
| 262 |
|
Again, see the CM manual for details. |
| 263 |
|
|
| 264 |
|
3. Parallel make is trying to be slightly smarter: When the master |
| 265 |
|
process finds a "bottleneck", i.e., when there is only one |
| 266 |
|
compilation unit that can be compiled and everybody else is |
| 267 |
|
waiting on it, then it will simply compile it directly instead |
| 268 |
|
of clumsily telling one of the slaves to do it. |
| 269 |
|
|
| 270 |
|
4. Support for "unsharing" added. This is necessary in order to be |
| 271 |
|
able to have two different versions of the same library running |
| 272 |
|
at the same time (e.g., for trying out a new MLRISC while still |
| 273 |
|
having the old MLRISC linked into the current compiler, etc.) |
| 274 |
|
See the CM manual. |
| 275 |
|
|
| 276 |
|
5. Simple "makedepend" functionality added for generating Makefile |
| 277 |
|
dependency information. (This is rather crude at the moment. |
| 278 |
|
Expect some changes here in the future.) |
| 279 |
|
|
| 280 |
|
6. ".fun" added as a recognized suffix for ML files. Also documented |
| 281 |
|
explicitly in the manual that the fallback behavior (unknown suffix |
| 282 |
|
-> ML file) is not an official feature! |
| 283 |
|
|
| 284 |
|
7. Small changes to the pickler for stable libraries. |
| 285 |
|
|
| 286 |
|
8. Several internal changes to CM (for cleanup/improvement). |

Description: |

|
1. I changed config/install.sh to remove duplicate entries from the |
| 298 |
|
lib/pathconfig file at the end. Moreover, the final version of |
| 299 |
|
lib/pathconfig is sorted alphabetically. The same (sorting) is done |
| 300 |
|
in src/system/installml. |
| 301 |
|
|
| 302 |
|
2. The config/install.sh script now consistently uses relative |
| 303 |
|
pathnames in lib/pathconfig whenever the anchor is in the lib |
| 304 |
|
directory. (So far this was true for the libraries that come |
| 305 |
|
pre-compiled and bundled as part of the bootfiles but not for |
| 306 |
|
libraries that are compiled by the script itself.) |

This update synchronizes my repository with Yale's. Most of these |
| 348 |
|
changes, however, do not affect SML/NJ at all (the RA is an exception). |
| 349 |
|
|
| 350 |
|
1. Register Allocator |
| 351 |
|
|
| 352 |
|
a. An improvement in the interference graph construction: |
| 353 |
|
Given a copy |
| 354 |
|
|
| 355 |
|
s <- t |
| 356 |
|
|
| 357 |
|
no interference edge between s and t is added for this definition of s. |
| 358 |
|
|
| 359 |
|
b. I've added two new spill heuristic modules that Fermin and I developed |
| 360 |
|
(in the new library RA.cm). These are unused in SML/NJ but maybe |
| 361 |
|
useful for others (Moby?) |
| 362 |
|
|
| 363 |
|
2. X86 |
| 364 |
|
|
| 365 |
|
a. Various fixes in the backend provided by Fermin [C--] and Lal. |
| 366 |
|
|
| 367 |
|
3. Alpha |
| 368 |
|
|
| 369 |
|
a. Added the BSR instruction and code generation that goes with it [C--] |
| 370 |
|
b. Other fixes too numerous to recount provided by Fermin [C--] |
| 371 |
|
|
| 372 |
|
4. Regmaps |
| 373 |
|
|
| 374 |
|
a. The regmaps are not initialized with the identity physical bindings |
| 375 |
|
at creation time. This is unneeded. |
| 376 |
|
|
| 377 |
|
5. MLRISC Optimizations |
| 378 |
|
|
| 379 |
|
a. The DJ-Graph module can now compute the iterated dominance frontiers |
| 380 |
|
intersects with liveness incrementally in linear time! Woohoo! |
| 381 |
|
This is now used in my new SSA construction algorithm. |
| 382 |
|
|
| 383 |
|
b. THe branch reorganization module is now smarter about linear chains of |

1. Fixed a problem in X86 assembly. |
| 466 |
|
|
| 467 |
|
Things like |
| 468 |
|
|
| 469 |
|
jmp %eax |
| 470 |
|
jmp (%eax) |
| 471 |
|
|
| 472 |
|
should be output as |
| 473 |
|
|
| 474 |
|
jmp *%eax |
| 475 |
|
jmp *(%eax) |
| 476 |
|
|
| 477 |
|
2. Assembly output |
| 478 |
|
|
| 479 |
|
Added a new flag |
| 480 |
|
|
| 481 |
|
"asm-indent-copies" (default to false) |
| 482 |
|
|
| 483 |
|
When this flag is on, parallel copies will be indented an extra level. |

All of these fixes are related to C--, Moby, and my own optimization |

3. Assembly |
| 504 |
|
|
| 505 |
|
When generating assemby, resolve the value of client defined constants, |
| 506 |
|
instead of generating symbolic values. This is controlled by the |
| 507 |
|
new flag "asm-resolve-constants", which is default to true. |
| 508 |
|
|
| 509 |
|
4. Machine Descriptions |
| 510 |
|
|
| 511 |
|
a. The precedence parser was slightly broken when parsing infixr symbols. |
| 512 |
|
b. The type generalizing code had the bound variables reversed, resulting |
| 513 |
|
in a problem during arity raising. |
| 514 |

Description: |
| 521 |
|
|
| 522 |
|
I eliminated coreEnv from compInfo. Access to the "Core" structure is |
| 523 |
|
now done via the ordinary static environment that is context to each |
| 524 |
|
compilation unit. |
| 525 |
|
|
| 526 |
|
To this end, I arranged that instead of "structure Core" as "structure |
| 527 |
|
_Core" is bound in the pervasive environment. Core access is done via |
| 528 |
|
_Core (which can never be accidentially rebound because _Core is not a |
| 529 |
|
legal surface-syntax symbol). |
| 530 |
|
|
| 531 |
|
The current solution is much cleaner because the core environment is |
| 532 |
|
now simply part of the pervasive environment which is part of every |
| 533 |
|
compilation unit's context anyway. In particular, this eliminates all |
| 534 |
|
special-case handling that was necessary until now in order to deal |
| 535 |
|
with dynamic and symbolic parts of the core environment. |
| 536 |
|
|
| 537 |
|
Remaining hackery (to bind the "magic" symbol _Core) is localized in the |
| 538 |
|
compilation mananger's bootstrap compiler (actually: in the "init group" |
| 539 |
|
handling). See the comments in src/system/smlnj/init/init.cmi for |
| 540 |
|
more details. |
| 541 |
|
|
| 542 |
|
I also tried to track down all mentions of "Core" (as string argument |
| 543 |
|
to Symbol.strSymbol) in the compiler and replaced them with a |
| 544 |
|
reference to the new CoreSym.coreSym. Seems cleaner since the actual |
| 545 |
|
name appears in one place only. |
| 546 |
|
|
| 547 |
|
Binfile and bootfile format have not changed, but the switchover from |
| 548 |
|
the old "init.cmi" to the new one is a bit tricky, so I supplied new |
| 549 |
|
bootfiles anyway. |

|
Description: |
| 566 |
|
|
| 567 |
|
This update contains a rewritten (and hopefully more correct) module |
| 568 |
|
for extracting aliasing information from CPS. |
| 569 |
|
|
| 570 |
|
To turn on this feature: |
| 571 |
|
|
| 572 |
|
Compiler.Control.CG.memDisambiguate := true |
| 573 |
|
|
| 574 |
|
To pretty print the region information with assembly |
| 575 |
|
|
| 576 |
|
Compiler.Control.MLRISC.getFlag "asm-show-region" := true; |
| 577 |
|
|
| 578 |
|
To control how many levels of aliasing information are printed, use: |
| 579 |
|
|
| 580 |
|
Compiler.Control.MLRISC.getInt "points-to-show-level" := n |
| 581 |
|
|
| 582 |
|
The default of n is 3. |

|
|

|
1. A small change to CM's handling of stable libraries: |
| 607 |
|
CM now maintains one "global" modmap that is used for all stable |
| 608 |
|
libraries. The use of such a global modmap maximizes sharing and |
| 609 |
|
minimizes the need for re-traversing parts of environments during |
| 610 |
|
modmap construction. (However, this has minor impact since modmap |
| 611 |
|
construction seems to account for just one percent or less of total |
| 612 |
|
compile time.) |
| 613 |
|
|
| 614 |
|
2. I added a "genmap" phase to the statistics. This is where I got the |
| 615 |
|
"one percent" number (see above). |
| 616 |
|
|
| 617 |
|
3. CM's new tool parameter mechanism just became _even_ better. :) |
| 618 |
|
- The parser understands named parameters and recursive options. |
| 619 |
|
- The "make" and "shell" tools use these new features. |
| 620 |
|
(This makes it a lot easier to cascade these tools.) |
| 621 |
|
- There is a small syntax change: named parameters use a |
| 622 |
|
|
| 623 |
|
<name> : ( <option> ... ) or |
| 624 |
|
<name> : <string> |
| 625 |
|
|
| 626 |
|
syntax. Previously, named parameters were implemented in an |
| 627 |
|
ad-hoc fashion by each tool individually (by parsing strings) |
| 628 |
|
and had the form |
| 629 |
|
|
| 630 |
|
<name>=<string> |
| 631 |
|
|
| 632 |
|
See the CM manual for a full description of these issues. |

This update contains: |
| 645 |
|
|
| 646 |
|
1. Moderate changes to CM: |
| 647 |
|
|
| 648 |
|
- Changes to CM's tools mechanism. In particular, it is now possible |
| 649 |
|
to have tools that accept additional "command line" parameters |
| 650 |
|
(specified in the .cm file at each instance where the tool's class is |
| 651 |
|
used). |
| 652 |
|
|
| 653 |
|
This was done to accomodate the new "make" and "shell" tools which |
| 654 |
|
facilitate fairly seemless hookup to portions of code managed using |
| 655 |
|
Makefiles or Shell scripts. |
| 656 |
|
|
| 657 |
|
There are no classes "shared" or "private" anymore. Instead, the |
| 658 |
|
sharing annotation is now a parameter to the "sml" class. |
| 659 |
|
|
| 660 |
|
There is a bit of generic machinery for implementing one's own |
| 661 |
|
tools that accept command-line parameters. However, I am not yet fully |
| 662 |
|
satisfied with that part, so expect changes here in the future. |
| 663 |
|
|
| 664 |
|
All existing tools are described in the CM manual. |
| 665 |
|
|
| 666 |
|
- Slightly better error handling. (CM now surpresses many followup |
| 667 |
|
error messages that tended to be more annoying than helpful.) |
| 668 |
|
|
| 669 |
|
2. Major changes to the compiler's static environment data structures. |
| 670 |
|
|
| 671 |
|
- no CMStaticEnv anymore. |
| 672 |
|
- no CMEnv, no "BareEnvironment" (actually, _only_ BareEnvironment, |
| 673 |
|
but it is called Environment), no conversions between different |
| 674 |
|
kinds of static environments |
| 675 |
|
|
| 676 |
|
- There is still a notion of a "modmap", but such modmaps are generated |
| 677 |
|
on demand at the time when they are needed. This sounds slow, but I |
| 678 |
|
sped up the code that generates modmaps enough for this not to lead to |
| 679 |
|
a slowdown of the compiler (at least I didn't detect any). |
| 680 |
|
|
| 681 |
|
- To facilitate rapid modmap generation, static environments now |
| 682 |
|
contain an (optional) "modtree" structure. Modtree annotations are |
| 683 |
|
constructed by the unpickler during unpickling. (This means that |
| 684 |
|
the elaborator does not have to worry about modtrees at all.) |
| 685 |
|
Modtrees have the advantage that they are compositional in the same |
| 686 |
|
way as the environment data structure itself is compositional. |
| 687 |
|
As a result, modtrees never hang on to parts of an environment that |
| 688 |
|
has already been rendered "stale" by filtering or rebinding. |
| 689 |
|
|
| 690 |
|
- I went through many, many trials and errors before arriving at the |
| 691 |
|
current solution. (The initial idea of "linkpaths" did not work.) |
| 692 |
|
But the result of all this is that I have touched a lot of files that |
| 693 |
|
depend on the "modules" and "types" data structures (most of the |
| 694 |
|
elaborator). There were a lot of changes during my "linkpath" trials |
| 695 |
|
that could have been reverted to their original state but weren't. |
| 696 |
|
Please, don't be too harsh on me for messing with this code a bit more |
| 697 |
|
than what was strictly necessary... (I _did_ resist the tempation |
| 698 |
|
of doing any "global reformatting" to avoid an untimely death at |
| 699 |
|
Dave's hands. :) |
| 700 |
|
|
| 701 |
|
- One positive aspect of the previous point: At least I made sure that |
| 702 |
|
all files that I touched now compile without warnings (other than |
| 703 |
|
"polyEqual"). |
| 704 |
|
|
| 705 |
|
- compiler now tends to run "leaner" (i.e., ties up less memory in |
| 706 |
|
redundant modmaps) |
| 707 |
