[armedbear-ticket] [armedbear] #90: resetSpecialBindings efficiency

#90: resetSpecialBindings efficiency -------------------------+-------------------------------------------------- Reporter: ehuelsmann | Owner: ehuelsmann Type: enhancement | Status: new Priority: major | Milestone: unscheduled Component: compiler | Version: Keywords: | -------------------------+-------------------------------------------------- The code {{{ (PROGN (DEFVAR *X*) (DEFUN F (*X*) (LET (*X*) (PRINT "OK")))) }}} will compile 2 specials-restoring blocks after the PRINT form: one for LET and one for the function argument list. If the function indicated to the body that it would be clearing the specials, the LET form could skip that action (being the last form in the body), reducing the number of CATCH/THROWs in case of non-local exits and the number of resetSpecialBindings() calls in case of normal exits. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/90> armedbear <http://common-lisp.net/project/armedbear> armedbear

[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

#70: Unboxing of simple strings / vectors -------------------------+-------------------------------------------------- Reporter: ehuelsmann | Owner: ehuelsmann Type: defect | Status: new Priority: major | Milestone: Component: compiler | Version: Keywords: performance | -------------------------+-------------------------------------------------- When so declared, simple strings and vectors can be unboxed to allow faster access. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/70> 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

#85: CL-JSON throws an error under ABCL where SBCL doesn't. ------------------------+--------------------------------------------------- Reporter: ehuelsmann | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Component: other | Version: Keywords: | ------------------------+--------------------------------------------------- The code is: (require 'asdf) (asdf:operate 'asdf:load-op :cl-json) (json:decode-json-from-string "{\"foo\": [10,20,50], \"bar\": true}") The error message is: The value 50 is not of type CONS. I'm using Yason as a work-around, but thought that you guys might want to know, maybe this points to a deeper issue. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/85> armedbear <http://common-lisp.net/project/armedbear> armedbear

#81: Inlining functions with &optional and other "complex" arguments -------------------------+-------------------------------------------------- Reporter: ehuelsmann | Owner: ehuelsmann Type: enhancement | Status: new Priority: major | Milestone: 0.20 Component: compiler | Version: Keywords: | -------------------------+-------------------------------------------------- Currently we only inline functions which have only required parameters. With a little bit more intelligence we could easily inline functions with optional parameters. With a bit more intelligence than that, we can even inline functions with &keyword and &rest parameters. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/81> armedbear <http://common-lisp.net/project/armedbear> armedbear
