commit 8ac08bcb910ad78d1a6879d30d653afeb7eccff5
Author: Andy Wingo <address@hidden>
Date:   Sun Jan 31 13:02:39 2010 +0100

    remove tracking of "active" status of jmpbuf smobs
    
    * libguile/throw.c: Remove code to track "active" status of jumpbuf, as
      it was unused.

commit 2d0778464c0ec373e194109744b393b450501ac9
Author: Andy Wingo <address@hidden>
Date:   Sun Jan 31 12:35:19 2010 +0100

    deprecate lazy-catch
    
    * libguile/deprecated.h:
    * libguile/deprecated.c (scm_internal_lazy_catch, scm_lazy_catch):
      Deprecate, and print out a nasty warning that people should change to
      with-throw-handler.
    
    * libguile/throw.h:
    * libguile/throw.c (scm_c_with_throw_handler): Deprecate the use of the
      lazy_catch_p argument, printing out a nasty warning if someone
      actually passes 1 as that argument. The combination of the pre-unwind
      and post-unwind handlers should be sufficient.
    
    * test-suite/tests/exceptions.test: Remove lazy-catch tests, as they are
      deprecated. Two of them fail:
      * throw/catch: effect of lazy-catch unwinding on throw to another key
      * throw/catch: repeat of previous test but with lazy-catch
      Hopefully people are not depending on this behavior, and the warning is
      sufficiently nasty for people to switch. We will see.
    
    * doc/ref/api-debug.texi:
    * doc/ref/api-control.texi: Update to remove references to lazy-catch,
      folding in the useful bits to with-throw-handler.

      constants.
      (prompt, control): Add primitive expanders to turn these into @prompt
      and @control.
    
    * module/ice-9/control.scm: New module, for delimited continuation
      operators.
    
    * module/Makefile.am: Add.

      when bootstrapping (ice-9 control).

    * module/language/assembly/disassemble.scm (code-annotation):
    * module/language/assembly/decompile-bytecode.scm (decode-load-program):
    * module/language/assembly/compile-bytecode.scm (write-bytecode):
      Assemble and disassemble `prompt' appropriately.

    tree-il -> glil compilation of prompt, dynamic-wind, control
    
    * module/language/tree-il/compile-glil.scm (flatten): Compile <prompt>,
      <dynamic-wind>, and <control>.

Author: Andy Wingo <address@hidden>
Date:   Sat Jan 30 15:51:44 2010 +0100

Author: Andy Wingo <address@hidden>
Date:   Sat Jan 30 15:49:50 2010 +0100

    tree-il analyzer and inliner handle <prompt>
    
    * module/language/tree-il/analyze.scm (analyze-lexicals): Add cases for
      <prompt>, <dynamic-wind>, and <control>. If a continuation is not
      referenced in the body of a prompt handler, mark the prompt as
      escape-only.
    * module/language/tree-il/inline.scm (inline!): Inline the handler of a
      prompt if it is a simple lambda.

commit 1bf78495e90d65911c9e012764deab589640f883
Author: Andy Wingo <address@hidden>
Date:   Sun Jan 31 20:30:46 2010 +0100

    dynamic-wind compilation to VM ops
    
    * module/language/tree-il/primitives.scm: Resolve calls to dynamic-wind
      to <dynamic-wind>, thereby inlining the dynwind to VM ops, and
      allowing inline allocation of the body thunk.

      continuations.
