#33: Measure the impact of filling stack trace information when performing GO/RETURN/THROW ----------------------------------------------------------------------+----- Reporter: vvoutilainen | Owner: somebody Type: task | Status: new Priority: minor | Milestone: unscheduled Component: component1 | Version: 1.0 Keywords: exception ConditionThrowable go return throw performance | ----------------------------------------------------------------------+----- Douglas R. Miles reported recently that java.lang.Throwable.fillInStackTrace() can be a very time consuming operation when instantiating Throwables or objects the class of which extends Throwable. A patch for overriding the fillInStackTrace() function with an empty implementation was created, it seems to be a performance gain, but a benchmark is required. ANSI tests test so many other things that it's difficult to compare the impact of the patch without a test that tests only GO/RETURN/THROW. -- Ticket URL: <http://127.0.0.1:8000/armedbear/ticket/33> armedbear <http://common-lisp.net/project/armedbear> armedbear

#38: CLOS :metaclass support ------------------------+--------------------------------------------------- Reporter: ehuelsmann | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Component: component1 | Version: Keywords: | ------------------------+--------------------------------------------------- Blake McBride reports: Running the code: (defclass meta-class1 (standard-class) (cv1 cv2 cv3) (:metaclass standard-class)) (defclass class1 (standard-object) (iv1 iv2 iv3) (:metaclass meta-class1)) The second object returns: #<STANDARD-CLASS CLASS1 {F673CC}> It should be: #<META-CLASS1 CLASS1 {F673CC}> Not only is it reporting the wrong class of class1 but it doesn't work either. I suppose ABCL doesn't support the :metaclass option. It just ignores it. The problem is that without that option ABCL's CLOS is severely limited. Any plans to fix this? Thanks.

[armedbear-ticket] [armedbear] #45: Support for passing unboxed arguments to local functions

#45: Support for passing unboxed arguments to local functions -------------------------+-------------------------------------------------- Reporter: ehuelsmann | Owner: ehuelsmann Type: enhancement | Status: new Priority: major | Milestone: Component: compiler | Version: Keywords: | -------------------------+-------------------------------------------------- It would save a great deal of boxing/unboxing, if local functions and self-calling recursive functions could pass and return unboxed values. Although passing unboxed values from the outside world is generally considered 'dependency on implementation details', recursive calls and calls to local functions should be able to depend on this: they get recompiled upon function redefinition anyway. One of the reasons for this ticket: with the improved type-derivations in Jan/Feb 2009, the cl-bench TAK test deteriorated: more boxing was performed. With this change, the (un)boxing can be eliminated, except for the first call (from the outside world). -- Ticket URL: <http://127.0.0.1:8000/armedbear/ticket/45> armedbear <http://common-lisp.net/project/armedbear> armedbear

#44: Unboxing of local variables with :float and :double representations -------------------------+-------------------------------------------------- Reporter: ehuelsmann | Owner: ehuelsmann Type: enhancement | Status: new Priority: major | Milestone: Component: compiler | Version: Keywords: | -------------------------+-------------------------------------------------- Currently, variables with :float or :double representations don't get stored unboxed. Since intermediate results of those types do get unboxed, this leads to additional boxing/unboxing. -- Ticket URL: <http://127.0.0.1:8000/armedbear/ticket/44> armedbear <http://common-lisp.net/project/armedbear> armedbear

#49: Support loading of compiled functions off byte arrays -------------------------+-------------------------------------------------- Reporter: ehuelsmann | Owner: somebody Type: enhancement | Status: new Priority: major | Milestone: Component: other | Version: Keywords: | -------------------------+-------------------------------------------------- loadCompiledFunction() in Lisp.java loads bytes out of a file, then loads the "class-bytes" off the resulting byte array. The result being a loaded class. The goal of this issue is to expose this interface in order to eliminate the need for the compiler to write compiled functions out to files before loading them into the JVM. -- Ticket URL: <http://127.0.0.1:8000/armedbear/ticket/49> armedbear <http://common-lisp.net/project/armedbear> armedbear
