(thanks to Shinmera) + * bug fix: SLOT-MAKUNBOUND does not attempt to dereference a PROGN variable + in the interpreter. + * bug fix: READ-SEQUENCE into displaced arrays with a non-zero offset now + writes to the right memory location. + * bug fix: fix some erroneous file position calculations in the editcore + utility (exposed by a change in the libzstd compression implementation). + * bug fix: do not break the build on STYLE-WARNINGs for earlier SBCL build + hosts. (lp#2064671, reported by Patrick Poitras) + * bug fix: various bug fixes for ppc64le (lp#2074275, reported by Claude R. C.) + * bug fix: address a rounding error in the TAN type deriver which led to a + miscompile in cl-pdf. (lp#2077100, reported by Gian Pierro Carrubba) + * bug fix: overoptimization of FIND with a :TEST of CHAR-EQUAL. (lp#2077539) + * optimization: detection of duplicate names in loaded code now scales + subquadratically. + * optimization: switch from Floyd's to Brent's cycle detection for lists. + * optimization: EQUAL on lists should be faster. + * optimization: fewer filesystem operations are performed when working out + what to LOAD. + * optimization: various microoptimizations on hash tables and + associated operations. + * optimization: strings are now hashed using FNV-1A, replacing Bob Jenkins' + one-at-a-time hash. + * optimization: fewer redundant validations of the sequence bounding indices + in POSITION on strings. + * optimization: many improvements to type derivation on the arguments to and + results of standard functions + * optimization: adding many (hundreds) methods to a generic function can be + done faster. + changes in sbcl-2.4.7 relative to sbcl-2.4.6: * minor incompatible change: the compiler will emit optimization notes related to complex type checks only at high SPEED optimization settings. |
