sbcl-1.3.14
b464cda2 · ·changes in sbcl-1.3.14 relative to sbcl-1.3.13: * minor incompatible change: the SB-PCL walker no longer recognizes macros expanding into a DECLARE expression. This is not a language change, since ANSI forbids such usage (X3J13 issue DECLARE-MACROS:FLUSH). * enhancement: for several macros such as MULTIPLE-VALUE-{BIND,SETQ}, COND, DO{,*,LIST}, {RESTART,HANDLER}-{BIND,CASE}, *CASE, conditions signaled during macroexpansion point to the form that caused the problem more accurately. * enhancement: the "--noinform" command-line option inhibits output from save-lisp-and-die in addition to removing the startup banner. * bug fix: PROCESS-KILL failed to return errno if the system call failed * optimization: slightly more comprehensive treatment of the keyword arguments to MAKE-ARRAY in compiler transformations. -

(lp#1645152) * enhancement: new Windows specific option to run-program, :escape-arguments (lp#1503496) * enhancement: recompiling a MAKE-INSTANCE form with an initarg :INITARG CONSTANT where CONSTANT names a constant variable picks up the new value of CONSTANT in case it has been redefined.

(lp#1082967) * optimization: memory consumption of each STANDARD-OBJECT instance is reduced by 2 words if the compact-instance-header feature is enabled. * optimization: CONDITION instances are quicker to allocate. * optimization: unoptimized calls to FILL on specialized vectors are now just as fast as T vectors. * bug fix: get-timezone returns corret DST on 64-bit Windows.

sbcl-1.3.12
c5bff76d · ·changes in sbcl-1.3.12 relative to sbcl-1.3.11: * enhancement: on x86-64, compiled functions loaded from fasl files can not be moved, but can be freed, by GC. Additionally, COMPILE will produce immobile code if SB-C::*COMPILE-TO-MEMORY-SPACE* is set to :IMMOBILE. (Caution: the flag is experimental and subject to change.) The benefits are better physical separation of code from data, and potentially easier examination of live images by external tools. * enhancement: the docstring for SAVE-LISP-AND-DIE has been amended to say that the :ROOT-STRUCTURES parameter is not meaningless on gencgc, depending on the platform. * bug fix: calling a named function (e.g. a DEFUN) concurrently with redefining that same function could lead to execution of random bytes. * bug fix: yes-or-no-p accepts formatter functions (lp#1639490) * bug fix: better handling of exceptions on macOS. -

(patch by Ilya Perminov, lp#1339924) * optimization: multiple-value-call is optimized with multiple argument forms, not just one. (lp#753803) * bug fix: MAKE-ALIEN-STRING returns the number of allocated bytes as a second value as advertised (reported by Johann 'Myrkraverk' Oskarsson) * bug fix: when TO-READTABLE is supplied to COPY-READTABLE, it will contain only the macros in FROM-READTABLE and no others. (lp#1631506) * enhancement: gencgc has been modified for x86-64 on Linux and macOS to a support mark-and-sweep as well as the traditional copying strategy. It is conceivable that some applications might be adversely affected. Please see ':immobile-space' in 'base-target-features.lisp-expr' for further details, and possible reasons to disable this feature. * enhancement: x86-64 supports shrinking the fixed overhead in a structure from 2 words to 1 word, reducing memory consumption in applications which create many small structures. -
