|
Description: |

|
20 |
|
Removed the native COPY and FCOPY instructions |
21 |
|
from all the architectures and replaced it with the |
22 |
|
explicit COPY instruction from the previous commit. |
23 |
|
|
24 |
|
It is now possible to simplify many of the optimizations |
25 |
|
modules that manipulate copies. This has not been |
26 |
|
done in this change. |

Tag: george-20011206-mlrisc-instruction |
32 |
|
Description: |
33 |
|
|
34 |
|
Changed the representation of instructions from being fully abstract |
35 |
|
to being partially concrete. That is to say: |
36 |
|
|
37 |
|
from |
38 |
|
type instruction |
39 |
|
|
40 |
|
to |
41 |
|
type instr (* machine instruction *) |
42 |
|
|
43 |
|
datatype instruction = |
44 |
|
LIVE of {regs: C.cellset, spilled: C.cellset} |
45 |
|
| KILL of {regs: C.cellset, spilled: C.cellset} |
46 |
|
| COPYXXX of {k: CB.cellkind, dst: CB.cell list, src: CB.cell list} |
47 |
|
| ANNOTATION of {i: instruction, a: Annotations.annotation} |
48 |
|
| INSTR of instr |
49 |
|
|
50 |
|
This makes the handling of certain special instructions that appear on |
51 |
|
all architectures easier and uniform. |
52 |
|
|
53 |
|
LIVE and KILL say that a list of registers are live or killed at the |
54 |
|
program point where they appear. No spill code is generated when an |
55 |
|
element of the 'regs' field is spilled, but the register is moved to |
56 |
|
the 'spilled' (which is present, more for debugging than anything else). |
57 |
|
|
58 |
|
LIVE replaces the (now deprecated) DEFFREG instruction on the alpha. |
59 |
|
We used to generate: |
60 |
|
|
61 |
|
DEFFREG f1 |
62 |
|
f1 := f2 + f3 |
63 |
|
trapb |
64 |
|
|
65 |
|
but now generate: |
66 |
|
|
67 |
|
f1 := f2 + f3 |
68 |
|
trapb |
69 |
|
LIVE {regs=[f1,f2,f3], spilled=[]} |
70 |
|
|
71 |
|
Furthermore, the DEFFREG (hack) required that all floating point instruction |
72 |
|
use all registers mentioned in the instruction. Therefore f1 := f2 + f3, |
73 |
|
defines f1 and uses [f1,f2,f3]! This hack is no longer required resulting |
74 |
|
in a cleaner alpha implementation. (Hopefully, intel will not get rid of |
75 |
|
this architecture). |
76 |
|
|
77 |
|
COPYXXX is intended to replace the parallel COPY and FCOPY available on |
78 |
|
all the architectures. This will result in further simplification of the |
79 |
|
register allocator that must be aware of them for coalescing purposes, and |
80 |
|
will also simplify certain aspects of the machine description that provides |
81 |
|
callbacks related to parallel copies. |
82 |
|
|
83 |
|
ANNOTATION should be obvious, and now INSTR represents the honest to God |
84 |
|
machine instruction set! |
85 |
|
|
86 |
|
The <arch>/instructions/<arch>Instr.sml files define certain utility |
87 |
|
functions for making porting easier -- essentially converting upper case |
88 |
|
to lower case. All machine instructions (of type instr) are in upper case, |
89 |
|
and the lower case form generates an MLRISC instruction. For example on |
90 |
|
the alpha we have: |
91 |
|
|
92 |
|
datatype instr = |
93 |
|
LDA of {r:cell, b:cell, d:operand} |
94 |
|
| ... |
95 |
|
|
96 |
|
val lda : {r:cell, b:cell, d:operand} -> instruction |
97 |
|
... |
98 |
|
|
99 |
|
where lda is just (INSTR o LDA), etc. |

|
137 |
|
1. Modifications to the SML/NJ code generator and to the runtime system |
138 |
|
so that code object name strings are directly inserted into code |
139 |
|
objects at code generation time. The only business the runtime system |
140 |
|
has with this is now to read the name strings on occasions. |
141 |
|
(The encoding of the name string has also changed somewhat.) |
142 |
|
|
143 |
|
2. CM now implements a simple "set calculus" for specifying export lists. |
144 |
|
In particular, it is now possible to refer to the export lists of |
145 |
|
other libraries/groups/sources and form unions as well as differences. |
146 |
|
See the latest CM manual for details. |
147 |
|
|
148 |
|
3. An separate notion of "proxy" libraries has again be eliminated from |
149 |
|
CM's model. (Proxy libraries are now simply a special case of using |
150 |
|
the export list calculus.) |
151 |
|
|
152 |
|
4. Some of the existing libraries now take advantage of the new set |
153 |
|
calculus. |
154 |
|
(Notice that not all libraries have been converted because some |
155 |
|
of the existing .cm-files are supposed to be backward compatible |
156 |
|
with 110.0.x.) |
157 |
|
|
158 |
|
5. Some cleanup in stand-alone programs. (Don't use "exnMessage" -- use |
159 |
|
"General.exnMessage"! The former relies on a certain hook to be |
160 |
|
initialized, and that often does not happen in the stand-alone case.) |

Implemented a complete redesign of MLRISC pseudo-ops. Now there |

ought to never be any question of incompatabilities with |
170 |
|
pseudo-op syntax expected by host assemblers. |
171 |
|
|
172 |
|
For now, only modules supporting GAS syntax are implemented |
173 |
|
but more should follow, such as MASM, and vendor assembler |
174 |
|
syntax, e.g. IBM as, Sun as, etc. |

|
Fix for a backpatching bug reported by Allen. |
197 |
|
|
198 |
|
Because the boundary between short and long span-dependent |
199 |
|
instructions is +/- 128, there are an astounding number of |
200 |
|
span-dependent instructions whose size is over estimated. |
201 |
|
|
202 |
|
Allen came up with the idea of letting the size of span |
203 |
|
dependent instructions be non-monotonic, for a maxIter |
204 |
|
number of times, after which the size must be monotonically |
205 |
|
increasing. |
206 |
|
|
207 |
|
This table shows the number of span-dependent instructions |
208 |
|
whose size was over-estimated as a function of maxIter, for the |
209 |
|
file Parse/parse/ml.grm.sml: |
210 |
|
|
211 |
|
maxIter # of instructions: |
212 |
|
10 687 |
213 |
|
20 438 |
214 |
|
30 198 |
215 |
|
40 0 |
216 |
|
|
217 |
|
In compiling the compiler, there is no significant difference in |
218 |
|
compilation speed between maxIter=10 and maxIter=40. Actually, |
219 |
|
my measurements showed that maxIter=40 was a tad faster than |
220 |
|
maxIter=10! Also 96% of the files in the compiler reach a fix |
221 |
|
point within 13 iterations, so fixing maxIter at 40, while high, |
222 |
|
is okay. |

234 |

NLFFIGEN: |
250 |

C definitions whose identifiers start with an underscore character |
252 |
|
* generate val bindings for enum constants |
253 |
|
* user can request that only one style (light or heavy) is being used; |
254 |
|
default is to use both (command-line arguments: -heavy and -light) |
255 |
|
* fixed bug in handling of function types involving incomplete pointers |
256 |
|
* generate ML entry points that take record arguments (i.e., using |
257 |

named arguments) for C functions that have a prototype with named |
258 |

I provided a non-hook implementation of exnName (at the toplevel) and |
316 |
|
made the "dummy" implementation of exnMessage (at the toplevel) more |
317 |
|
useful: if nothing gets "hooked in", then at least you are going to |
318 |
|
see the exception name and a message indicating why you don't see more. |
319 |
|
|
320 |
|
[For the time being, programs that need exnMessage and want to use |
321 |
|
ml-build should either use General.exnMessage (strongly recommended) or |
322 |
|
refer to structure General at some other point so that CM sees a |
323 |
|
static dependency.] |
324 |
|
|
325 |
|
[Similar remarks go for "print" and "use": If you want to use their |
326 |
|
functionality in stand-alone programs generated by ml-build, then use |
327 |
|
TextIO.output and Backend.Interact.useFile (from $smlnj/compiler.cm).] |

0. Updated the BOOT file (something that I forgot to do earlier). |
344 |

345 |

1. Small internal change to CM so that it avoids "/../" in filenames |
346 |
|
as much as possible (but only where it is safe). |
347 |
|
|
348 |
|
2. Changed config/_run-sml (resulting in a changed bin/.run-sml) so |
349 |
|
that arguments that contain delimiters are passed through correctly. |
350 |
|
This change also means that all "special" arguments of the form |

@SMLxxx... must come first. |

I changed the default setting of the Control.MLRISC.getFlag "x86-fast-fp" |
391 |
|
flag to "true". Everything seems to compile to a fixpoint ok, and |
392 |
|
"mandelbrot" speeds up by about 15%. |

1. Stefan Monnier's patch to fix a miscompilation problem that |
401 |
|
was brought to light by John Reppy's work on Moby. |
402 |
|
|
403 |
|
2. Implemented a minimal "structure Compiler" that contains just |
404 |
|
"version" and "architecture". The minimal version will be |
405 |
|
available when the full version is not. This is for backward- |
406 |
|
compatibility with code that wants to test Compiler.version. |
