|
Description: |
| 19 |
|
|
| 20 |
|
Changed the representation of instructions from being fully abstract |
| 21 |
|
to being partially concrete. That is to say: |
| 22 |
|
|
| 23 |
|
from |
| 24 |
|
type instruction |
| 25 |
|
|
| 26 |
|
to |
| 27 |
|
type instr (* machine instruction *) |
| 28 |
|
|
| 29 |
|
datatype instruction = |
| 30 |
|
LIVE of {regs: C.cellset, spilled: C.cellset} |
| 31 |
|
| KILL of {regs: C.cellset, spilled: C.cellset} |
| 32 |
|
| COPYXXX of {k: CB.cellkind, dst: CB.cell list, src: CB.cell list} |
| 33 |
|
| ANNOTATION of {i: instruction, a: Annotations.annotation} |
| 34 |
|
| INSTR of instr |
| 35 |
|
|
| 36 |
|
This makes the handling of certain special instructions that appear on |
| 37 |
|
all architectures easier and uniform. |
| 38 |
|
|
| 39 |
|
LIVE and KILL say that a list of registers are live or killed at the |
| 40 |
|
program point where they appear. No spill code is generated when an |
| 41 |
|
element of the 'regs' field is spilled, but the register is moved to |
| 42 |
|
the 'spilled' (which is present, more for debugging than anything else). |
| 43 |
|
|
| 44 |
|
LIVE replaces the (now deprecated) DEFFREG instruction on the alpha. |
| 45 |
|
We used to generate: |
| 46 |
|
|
| 47 |
|
DEFFREG f1 |
| 48 |
|
f1 := f2 + f3 |
| 49 |
|
trapb |
| 50 |
|
|
| 51 |
|
but now generate: |
| 52 |
|
|
| 53 |
|
f1 := f2 + f3 |
| 54 |
|
trapb |
| 55 |
|
LIVE {regs=[f1,f2,f3], spilled=[]} |
| 56 |
|
|
| 57 |
|
Furthermore, the DEFFREG (hack) required that all floating point instruction |
| 58 |
|
use all registers mentioned in the instruction. Therefore f1 := f2 + f3, |
| 59 |
|
defines f1 and uses [f1,f2,f3]! This hack is no longer required resulting |
| 60 |
|
in a cleaner alpha implementation. (Hopefully, intel will not get rid of |
| 61 |
|
this architecture). |
| 62 |
|
|
| 63 |
|
COPYXXX is intended to replace the parallel COPY and FCOPY available on |
| 64 |
|
all the architectures. This will result in further simplification of the |
| 65 |
|
register allocator that must be aware of them for coalescing purposes, and |
| 66 |
|
will also simplify certain aspects of the machine description that provides |
| 67 |
|
callbacks related to parallel copies. |
| 68 |
|
|
| 69 |
|
ANNOTATION should be obvious, and now INSTR represents the honest to God |
| 70 |
|
machine instruction set! |
| 71 |
|
|
| 72 |
|
The <arch>/instructions/<arch>Instr.sml files define certain utility |
| 73 |
|
functions for making porting easier -- essentially converting upper case |
| 74 |
|
to lower case. All machine instructions (of type instr) are in upper case, |
| 75 |
|
and the lower case form generates an MLRISC instruction. For example on |
| 76 |
|
the alpha we have: |
| 77 |
|
|
| 78 |
|
datatype instr = |
| 79 |
|
LDA of {r:cell, b:cell, d:operand} |
| 80 |
|
| ... |
| 81 |
|
|
| 82 |
|
val lda : {r:cell, b:cell, d:operand} -> instruction |
| 83 |
|
... |
| 84 |
|
|
| 85 |
|
where lda is just (INSTR o LDA), etc. |

|
1. Modifications to the SML/NJ code generator and to the runtime system |
| 124 |
|
so that code object name strings are directly inserted into code |
| 125 |
|
objects at code generation time. The only business the runtime system |
| 126 |
|
has with this is now to read the name strings on occasions. |
| 127 |
|
(The encoding of the name string has also changed somewhat.) |
| 128 |
|
|
| 129 |
|
2. CM now implements a simple "set calculus" for specifying export lists. |
| 130 |
|
In particular, it is now possible to refer to the export lists of |
| 131 |
|
other libraries/groups/sources and form unions as well as differences. |
| 132 |
|
See the latest CM manual for details. |
| 133 |
|
|
| 134 |
|
3. An separate notion of "proxy" libraries has again be eliminated from |
| 135 |
|
CM's model. (Proxy libraries are now simply a special case of using |
| 136 |
|
the export list calculus.) |
| 137 |
|
|
| 138 |
|
4. Some of the existing libraries now take advantage of the new set |
| 139 |
|
calculus. |
| 140 |
|
(Notice that not all libraries have been converted because some |
| 141 |
|
of the existing .cm-files are supposed to be backward compatible |
| 142 |
|
with 110.0.x.) |
| 143 |
|
|
| 144 |
|
5. Some cleanup in stand-alone programs. (Don't use "exnMessage" -- use |
| 145 |
|
"General.exnMessage"! The former relies on a certain hook to be |
| 146 |
|
initialized, and that often does not happen in the stand-alone case.) |

Description: |

|
Implemented a complete redesign of MLRISC pseudo-ops. Now there |
| 155 |
|
ought to never be any question of incompatabilities with |
| 156 |
|
pseudo-op syntax expected by host assemblers. |
| 157 |
|
|
| 158 |
|
For now, only modules supporting GAS syntax are implemented |
| 159 |
|
but more should follow, such as MASM, and vendor assembler |
| 160 |
|
syntax, e.g. IBM as, Sun as, etc. |

|
Fix for a backpatching bug reported by Allen. |
| 183 |
|
|
| 184 |
|
Because the boundary between short and long span-dependent |
| 185 |
|
instructions is +/- 128, there are an astounding number of |
| 186 |
|
span-dependent instructions whose size is over estimated. |
| 187 |
|
|
| 188 |
|
Allen came up with the idea of letting the size of span |
| 189 |
|
dependent instructions be non-monotonic, for a maxIter |
| 190 |
|
number of times, after which the size must be monotonically |
| 191 |
|
increasing. |
| 192 |
|
|
| 193 |
|
This table shows the number of span-dependent instructions |
| 194 |
|
whose size was over-estimated as a function of maxIter, for the |
| 195 |
|
file Parse/parse/ml.grm.sml: |
| 196 |
|
|
| 197 |
|
maxIter # of instructions: |
| 198 |
|
10 687 |
| 199 |
|
20 438 |
| 200 |
|
30 198 |
| 201 |
|
40 0 |
| 202 |
|
|
| 203 |
|
In compiling the compiler, there is no significant difference in |
| 204 |
|
compilation speed between maxIter=10 and maxIter=40. Actually, |
| 205 |
|
my measurements showed that maxIter=40 was a tad faster than |
| 206 |
|
maxIter=10! Also 96% of the files in the compiler reach a fix |
| 207 |
|
point within 13 iterations, so fixing maxIter at 40, while high, |
| 208 |
|
is okay. |

CKIT: |

* Changed the return type of TypeUtil.getFunction accordingly. |
| 220 |

if there is a mismatch. |

NLFFIGEN: |
| 236 |
|
* temporarily disabled the mechanism that suppresses ML output for |

|
C definitions whose identifiers start with an underscore character |
| 238 |
|
* generate val bindings for enum constants |
| 239 |
|
* user can request that only one style (light or heavy) is being used; |
| 240 |
|
default is to use both (command-line arguments: -heavy and -light) |
| 241 |
|
* fixed bug in handling of function types involving incomplete pointers |
| 242 |
|
* generate ML entry points that take record arguments (i.e., using |
| 243 |
|
named arguments) for C functions that have a prototype with named |

arguments |

I provided a non-hook implementation of exnName (at the toplevel) and |
| 302 |
|
made the "dummy" implementation of exnMessage (at the toplevel) more |
| 303 |
|
useful: if nothing gets "hooked in", then at least you are going to |
| 304 |
|
see the exception name and a message indicating why you don't see more. |
| 305 |
|
|
| 306 |
|
[For the time being, programs that need exnMessage and want to use |
| 307 |
|
ml-build should either use General.exnMessage (strongly recommended) or |
| 308 |
|
refer to structure General at some other point so that CM sees a |
| 309 |
|
static dependency.] |

|

[Similar remarks go for "print" and "use": If you want to use their |

functionality in stand-alone programs generated by ml-build, then use |

|
TextIO.output and Backend.Interact.useFile (from $smlnj/compiler.cm).] |

0. Updated the BOOT file (something that I forgot to do earlier). |
| 330 |
|
|
| 331 |
|
1. Small internal change to CM so that it avoids "/../" in filenames |
| 332 |
|
as much as possible (but only where it is safe). |
| 333 |
|
|
| 334 |
|
2. Changed config/_run-sml (resulting in a changed bin/.run-sml) so |
| 335 |
|
that arguments that contain delimiters are passed through correctly. |
| 336 |
|
This change also means that all "special" arguments of the form |
| 337 |
|
@SMLxxx... must come first. |
| 338 |
|
|
| 339 |
|
3. Changed install script to put relative anchor names for tool commands |
| 340 |
|
into pathconfig. |

I changed the default setting of the Control.MLRISC.getFlag "x86-fast-fp" |
| 377 |
|
flag to "true". Everything seems to compile to a fixpoint ok, and |
