Failure to use ABCL as SBCL compilation host

[mevenson]

loke noticed that ABCL is no longer able to host a compilation of SBCL.

This failure occurs on both 1.4.0-dev and 1.3.1, so the problem has been present for a while.

One can get this point in a naked REPL via executing the following form on the source tree:

  (load "~/src/sbcl-1.2.3/make-host-1.lisp")

SB!IMPL::DECL-EXPR is not being used as a function in the compilation, so something is mucked up in the DEFOPTIMIZER macro transformation.

DECL-EXPR is used in src/code/early-extensions.lisp in the definition of SB!IMPL::BINDING* in a manner that looks like a function invocation. Why is this not the case?

                (let ((continue (acond ((cdr bindings) (recurse it rest-decls))
                                       (t (append decls forms)))))
                  `((multiple-value-bind ,names ,value-form
                      ,@(decl-expr binding-decls ignores)
                      ,@(ecase flag
                          ((nil) continue)
                          ((:exit-if-null)
                           `((when ,(first names) ,@continue))))))))))

Replying to mevenson:

DECL-EXPR is used in src/code/early-extensions.lisp in the definition of SB!IMPL::BINDING* in a manner that looks like a function invocation. Why is this not the case?

Because the ,@ operator is not correctly splicing as a list.

The cause of the problems may not necessarily be a problem introduced in ABCL.

See <​http://christophe.rhodes.io/notes/blog/posts/2014/still_working_on_reproducible_builds/> for Christophe's exposition on problems within SBCL.

[dkatzman2002]

ABCL can build SBCL now, and you can probably close this, though ticket 351 is still open and genuinely a bug.
