REPORT output + has also additional sorting options. + * optimization: structure allocation has been improved + ** constructors created by non-toplevel DEFSTRUCTs are ~40% faster. + ** out of line constructors are ~10% faster. + ** inline constructors are ~15% faster. + ** inline constructors are capable of dynamic extent allocation + (generally on x86 and x86-64, in some cases on other platforms + as well.) + * optimization: simple uses of HANDLER-CASE and HANDLER-BIND no + longer cons. + * optimization: file compiler is now able to coalesce non-circular + lists, non-base strings, and bit-vectors. Additionally, constants + are never referenced through SYMBOL-VALUE at runtime. + * bug fix: EAI_NODATA is deprecated since RFC 3493. Stop using it + in sb-bsd-sockets. + * fixed some bugs revealed by Paul Dietz' test suite: + ** NIL is a valid function name (regression at 1.0.13.38) + ** FILL on lists was missing its return value (regression at 1.0.12.27) + ** STRING-TRIM, STRING-LEFT-TRIM, and STRING-RIGHT-TRIM did not respect + fill pointers properly (regression at 1.0.12.23) + ** STRING-TRIM, STRING-LEFT-TRIM, and STRING-RIGHT-TRIM did not respect + displacement indices properly (regression at 1.0.12.23) + +changes in sbcl-1.0.17 relative to 1.0.16: + * temporary regression: user code can no longer allocate closure + variable storage on stack, due to bug 419 without explicitly + requesting it. Please consult sbcl-devel for advice if you need to + use this feature in the meanwhile. + * new feature: runtime argument --control-stack-size can be used to + adjust thread default control stack size. + * enhancement: improved TIME output + ** all times are reported using the measured accuracy (milliseconds + for real and GC times, microseconds for everything else.) + ** processor cycle counts on x86 and x86-64. + ** interpreted forms are counted for both evaluator modes. + ** number of lambdas converted by the compiler is reported. + ** CPU percentage report (computed from real and total run time.) + ** more comprehensive run time reporting, using a condenced format + ** interperted form, lambda, and page fault counts are omitted + when zero. + * optimization: ADJOIN and PUSHNEW are upto ~70% faster in normal + SPEED policies. + * optimization: APPEND is upto ~10% faster in normal SPEED policies. + * optimization: two argument forms of LAST are upto ~10% faster + in normal SPEED policies. + * optimization: NCONC no longer needs to heap cons its &REST list + in normal SPEED policies. + * bug fix: SB-FLUID build feature no longer breaks the build. (thanks + to Sidney Markowitz) + * bug fix: UNION and NUNION work with :TEST-NOT once more, + regression since 1.0.9.1. (thanks to Eric Marsden) + * bug fix: result of MAKE-ARRAY can be stack allocated - regression + since 1.0.15.36. (thanks to Paul Khuong) + * bug fix: LAST when always returned the whole list when given a bignum + as the second argument. + * bug fix: dynamic extent allocation of nested lists and vectors + could leak to otherwise accessible parts. + * bug fix: invalid optimization of heap-allocated alien variable + reference. + * bug fix: fasl header checking is less vulnerable to different + platform word lengths. + * bug fix: more correct assembler syntax for GNU binutils + 2.18.50.0.4 support. (thanks to Marijn Schouten) + * bug fix: fix ECASE warnings from CMUCL-as-xc-host. (reported by + Andreas Franke) + * bug fix: the fopcompiler can handle LOCALLY forms (with no + declarations) successfully. (reported by Attila Lendvai) + changes in sbcl-1.0.16 relative to 1.0.15: + * minor incompatible change: revert the changes to sb-posix's error + signaling added in 1.0.14. * minor incompatible change: change PROBE-FILE back to returning NIL whenever we can't get a truename, as was the case before 1.0.14. + * minor incompatible change: SB-BSD-SOCKETS:NAME-SERVICE-ERROR now + inherits from ERROR instead of just CONDITION. + * new feature: SB-INTROSPECT can provide source locations for instances + as well. (thanks to Tobian Ritterweiler) + * optimization: binding special variables now generates smaller code + on threaded platforms. + * optimization: MEMBER and ASSOC are over 50% faster for :TEST #'EQ + and cases where no :TEST is given but the compiler can infer that + the element to search is of type (OR FIXNUM (NOT NUMBER)). + * optimization: better LOGNOT on fixnums. + * optimization: modular arithmetic for a particular requested width + is implemented using a tagged representation unless a better + representation is available. + * fixed bug 423: TRULY-THE and *CHECK-CONSISTENCY* interaction. + * bug fix: SB-BSD-SOCKETS:MAKE-INET-ADDRESS checks the input string + for wellformedness and returns a specialized vector. (reported by + Francois-Rene Rideau) + * bug fix: FIND-CLASS was not thread-safe. (reported by Attila Lendvai) + * bug fix: ~R was broken for vigtillions. (thanks to Luis Oliveira) + * bug fix: attempt to obtain *SCHEDULER-LOCK* recursively when + unscheduling timer at the same time as another timer fires. + * bug fix: don't reschedule timers for dead threads. + * bug fix: periodic polling was broken. (thanks to Espen S Johnsen) + * bug fix: copying output from RUN-PROGRAM to a stream signalled + bogus errors if select() was interrupted. * enhancement: add support for fcntl's struct flock to SB-POSIX. changes in sbcl-1.0.15 relative to sbcl-1.0.14:
