|
Description: |
| 20 |
|
|
| 21 |
|
I changed the handling of varargs in ml-nlffigen again: |
| 22 |
|
The ellipsis ... will now simply be ignored (with an accompanying warning). |
| 23 |
|
|
| 24 |
|
The immediate effect is that you can actually call a varargs function |
| 25 |
|
from ML -- but you can't actually supply any arguments beyond the ones |
| 26 |
|
specified explicitly. (For example, you can call printf with its format |
| 27 |
|
string, but you cannot pass additional arguments.) |
| 28 |
|
|
| 29 |
|
This behavior is only marginally more useful than the one before, but |
| 30 |
|
it has the advantage that a function or, more importantly, a function |
| 31 |
|
type never gets dropped on the floor, thus avoiding follow-up problems with |
| 32 |
|
other types that refer to the offending one. |

|
1. ckit-lib.cm now exports structure Error |
| 41 |
|
2. ml-nlffigen reports occurences of "..." (i.e., varargs function types) |
| 42 |
|
with a warning accompanied by a source location. Moreover, it |
| 43 |
|
merely skips the offending function or type and proceeds with the |
| 44 |
|
rest of its work.u As a result, one can safely feed C code containing |
| 45 |
|
"..." to ml-nlffigen. |
| 46 |
|
3. There are some internal improvements to CM, providing slightly |
| 47 |
|
more general string substitutions in the tools subsystem. |

Description: |

|
Fixed a small bug in CM's handling of parallel compilation. |
| 56 |
|
(You could observe the bug by Control-C-interrupting an ordinary |
| 57 |
|
CMB.make or CM.stabilize and then attaching some compile servers. |
| 58 |
|
The result was that all of a sudden the previously interrupted |
| 59 |
|
compilation would continue on its own. This was because of |
| 60 |
|
an over-optimization: CM did not bother to clean out certain queues |
| 61 |
|
when no servers were attached "anyway", resulting in the contents |
| 62 |
|
of these queues to grab control when new servers did get attached.) |
| 63 |
|
|
| 64 |
|
There is also another minor update to the CM manual. |

Description: |

|
|
| 89 |
|
This update fixes a number of minor bugs in ml-nlffigen as reported by |
| 90 |
|
Nick Carter <nbc@andrew.cmu.edu>. |
| 91 |
|
|
| 92 |
|
1. Silly but ok typedefs of the form "typedef void myvoid;" are now accepted. |
| 93 |
|
2. Default names for generated files are now derived from the name of |
| 94 |
|
the C file *without its directory*. In particular, this causes generated |
| 95 |
|
files to be placed locally even if the C file is in some system directory. |
| 96 |
|
3. Default names for generated signatures and structures are also derived |
| 97 |
|
from the C file name without its directory. This avoids silly things |
| 98 |
|
like "structure GL/GL". |
| 99 |
|
(Other silly names are still possible because ml-nlffigen does not do |
| 100 |
|
a thorough check of whether generated names are legal ML identifiers. |
| 101 |
|
When in doubt, use command line arguments to force particular names.) |

Here is a short late-hour update related to Sparc c-calls: |
| 163 |
|
|
| 164 |
|
-- made handling of double-word arguments a bit smarter |
| 165 |
|
|
| 166 |
|
-- instruction selection phase tries to collapse certain clumsily |
| 167 |
|
constructed ML-Trees; typical example: |
| 168 |
|
|
| 169 |
|
ADD(ty,ADD(_,e,LI d1),LI d2) -> ADD(ty,e,LI(d1+d2)) |
| 170 |
|
|
| 171 |
|
This currently has no further impact on SML/NJ since mlriscGen does |
| 172 |
|
not seem to generate such patterns in the first place, and c-calls |
| 173 |
|
(which did generate them in the beginning) has meanwhile been fixed |
| 174 |
|
so as to avoid them as well. |

|
Description: |
| 181 |
|
|
| 182 |
|
The purpose of this update is to provide an implementation of NLFFI |
| 183 |
|
on Sparc machines. |
| 184 |
|
|
| 185 |
|
Here are the changes in detail: |
| 186 |
|
|
| 187 |
|
* src/MLRISC/sparc/c-calls/sparc-c-calls.sml is a new file containing |
| 188 |
|
the Sparc implementation of the c-calls API. |
| 189 |
|
* The Sparc backend of SML/NJ has been modified to uniformely use %fp |
| 190 |
|
for accessing the ML frame. Thus, we have a real frame pointer and |
| 191 |
|
can freely modify %sp without need for an omit-frame-ptr phase. |
| 192 |
|
The vfp logic in src/compiler/CodeGen/* has been changed to accomodate |
| 193 |
|
this case. |
| 194 |
|
* ml-nlffigen has been taught to produce code for different architectures |
| 195 |
|
and calling conventions. |
| 196 |
|
* In a way similar to what was done in the x86 case, the Sparc |
| 197 |
|
backend uses its own specific extension to mltree. (For example, |
| 198 |
|
it needs to be able to generate UNIMP instructions which are part |
| 199 |
|
of the calling convention.) |
| 200 |
|
* ml-nlffi-lib was reorganized to make it more modular (in particular, |
| 201 |
|
to make it easier to plug in new machine- and os-dependent parts). |
| 202 |
|
|
| 203 |
|
There are some other fairly unrelated bug fixes and cleanups as well: |
| 204 |
|
|
| 205 |
|
* I further hacked the .cm files for MLRISC tools (like MDLGen) so |
| 206 |
|
that they properly share their libraries with existing SML/NJ libraries. |
| 207 |
|
* I fixed a minor cosmetic bug in CM, supressing certain spurious |
| 208 |
|
follow-up error messages. |
| 209 |
|
* Updates to CM/CMB documentation. |
| 210 |
|
|
| 211 |
|
TODO items: |
| 212 |
|
|
| 213 |
|
* MLRISC should use a different register as its asmTemp on the Sparc. |
| 214 |
|
(The current %o2 is a really bad choice because it is part of the |
| 215 |
|
calling conventions, so things might interfere in unexpected ways.) |

Description: |

|
|
| 223 |
|
A number of internal changes related to C calls and calling conventions: |
| 224 |
|
|
| 225 |
|
1. ML-Tree CALL statements now carry a "pops" field. It indicates the |
| 226 |
|
number of bytes popped implicitly (by the callee). In most cases |
| 227 |
|
this field is 0 but on x86/win32 it is some non-zero value. This |
| 228 |
|
is information provided for the benefit of the "omit-frameptr" pass. |
| 229 |
|
2. The CALL instruction on the x86 carries a similar "pops" field. |
| 230 |
|
The instruction selection phase copies its value from the ML-Tree |
| 231 |
|
CALL statement. |
| 232 |
|
3. On all other architectures, the instruction selection phase checks |
| 233 |
|
whether "pops=0" and complains if not. |
| 234 |
|
4. The c-calls implementation for x86 now accepts two calling conventions: |
| 235 |
|
"ccall" and "stdcall". When "ccall" is selected, the caller cleans |
| 236 |
|
up after the call and pops is set to 0. For "stdcall", the caller |
| 237 |
|
does nothing, leaving the cleanup to the callee; pops is set to |
| 238 |
|
the number of bytes that were pushed onto the stack. |
| 239 |
|
5. The cproto decoder (compiler/Semant/types/cproto.sml) now can |
| 240 |
|
distinguish between "ccall" and "stdcall". |
| 241 |
|
6. The UNIMP instruction has been added to the supported Sparc instruction |
| 242 |
|
set. (This is needed for implementing the official C calling convention |
| 243 |
|
on this architecture.) |
| 244 |
|
7. I fixed some of the .cm files under src/MLRISC/Tools to make them |
| 245 |
|
work with the latest CM. |
| 246 |
|
|
| 247 |

|
0. The "lambdasplit" parameter for class "sml" in CM has been documented. |
| 254 |
|
|
| 255 |
|
1. CM can now generate "index files". These are human-readable files |
| 256 |
|
that list on a per-.cm-file basis each toplevel symbol defined or |
| 257 |
|
imported. The location of the index file for |
| 258 |
|
<p>/<d>.cm is <p>/CM/INDEX/<d>.cm. |
| 259 |
|
To enable index-file generation, set CM.Control.generate_index to true |
| 260 |
|
or export an environment-symbol: export CM_GENERATE_INDEX=true. |
| 261 |
|
|
| 262 |
|
The CM manual has been updated accordingly. |
| 263 |
|
|
| 264 |
|
2. I made some slight modifications to the c-calls API in MLRISC. |
| 265 |
|
|
| 266 |
|
a) There is now a callback to support saving/restoring of |
| 267 |
|
dedicated but caller-save registers around the actual call |
| 268 |
|
instruction. |
| 269 |
|
b) One can optionally specify a comment-annotation for the |
| 270 |
|
call instruction. |
| 271 |
|
|
| 272 |
|
3. SML/NJ (mlriscGen.sml) uses this new API for the rawccall primop. |
| 273 |
|
(For example, the comment annotation shows the C prototype of |
| 274 |
|
the function being called.) |
