[Sbcl-devel] patches (+ problem building with cmucl)

[Martin A. <ma...@at...>]

Hi,

I've ported some of the latest patches from cmucl-18c
to SBCL.

Namely, what the attached patch does is the following
(this is also still annotated in the code, e.g. the places that
are affected):

- package-data-list:
MNA: cmucl-commit: Mon, 4 Dec 2000 13:50:25 -0800 (PST)
No need to export the unused symbols %function-header-arglist
%function-header-name %function-header-type.

- code/debug-int:
 MNA: cmucl-commit: Mon, 6 Nov 2000 10:08:39 -0800 (PST)
 Upon a stack trace ambiguity in x86-call-context, choose the lisp
 frame in preference to the C frame as this is frame of interest.

 MNA: cmucl-commit: Mon, 6 Nov 2000 09:48:00 -0800 (PST)
 Limit the stack trace failure warning in x86-call-context to fails for
 the immediate frame rather failures deeper within the search.

- code/late-target-error:
Catch missing slots in condition-reader-function, and signal an error.

- code/pprint:
 MNA: cmucl-commit: Wed, 27 Dec 2000 07:42:40 -0800 (PST)
 pprint-newline, pprint-indent, and pprint-tab should do nothing if
 *print-pretty* is not true.

- code/print:
MNA: cmucl-commit: Mon, 1 Jan 2001 01:30:53 -0800 (PST)
 Correct the pretty printing by print-unreadable-object. Only attempt
 to print pretty when the stream is a pretty-stream (and when
*print-pretty*)
 to ensure that all output goes to the same stream. 

 MNA: cmucl-commit: Wed, 27 Dec 2000 05:24:30 -0800 (PST)
 Have print-unreadable-object respect *print-pretty*.

 MNA: cmucl-commit: Mon, 1 Jan 2001 03:41:18 -0800 (PST)
 Fix output-character to escape the char-name. Reworking quote-string
 to not write the delimiting quotes so that is can be used by
 output-character.

- compiler/byte-comp:
MNA: cmucl-commit: Tue, 26 Sep 2000 09:41:00 -0700 (PDT)
Within generate-byte-code-for-set, avoid trying to set a lexical
variable with no refs since the compiler deletes such variables.

- compiler/eval:
 MNA: cmucl-commit: Tue, 26 Sep 2000 09:40:37 -0700 (PDT)
 Within set-leaf-value-lambda-var, avoid trying to set a lexical
 variable with no refs since the compiler deletes such variables.

- compiler/srctran:
 cmucl-commit: Wed, 3 Jan 2001 21:49:12 -0800 (PST)
 Rework the 'ash derive-type optimizer so better handle large negative
bounds.
 Based on suggestions from Raymond Toy.

- pcl/boot:
 MNA: add a defensive decl to parse defmethod, as well.
 MNA: cmucl-commit: Tue, 19 Dec 2000 06:26:31 -0800 (PST)
 Add a defensive declaration to PARSE-SPECIALIZERS.

- pcl/fast-init:
MNA: cmucl-commit Sat, 27 Jan 2001 07:07:45 -0800 (PST)
Silence compiler warnings about undefined function
<hairy-make-instance-name>
when compiling a method containing a make-instance call.

- runtime/print.c:
MNA: cmucl-commit Tue, 9 Jan 2001 11:46:57 -0800 (PST)
Correct the printing of instance objects for which the length was
being incorrectly calculated.

In addition:
I have tried to build current CVS SBCL with CMU CL (2.4.19).
It turned out that CMU CL does not like the DEFCONSTANT-EQX
macro in its current form, so it was necessary to include a
(IMHO) ugly hack in the macro (in src/code/early-extensions).
This might not be that severe, since it does not cause
any problems _yet_, as a "grep" showed ...
By this means, I'm at least able to build SBCL with CMU CL.
