(reported by Andreas Fuchs) * bug fix: RUN-PROGRAM now does not fail if some element in $PATH names a non-existent directory. (thanks to Andreas Fuchs) + * bug fix: ROUND and TRUNCATE could, under certain circumstances on + the PPC platform, lead to stack corruption; this has been fixed. + (reported by Rainer Joswig) + * bug fix: ASH on an (UNSIGNED-BYTE 32) with a shift of -32 or lower + no longer ever returns 1 instead of 0. (thanks to Lars Brinkhoff) * optimization: restored some effective method precomputation in CLOS (turned off by an ANSI fix in sbcl-0.8.3); the amount of precomputation is now tunable. * optimization: compiler-internal data structure use has been reviewed, and changes have been made that should improve the performance of the compiler by about 20%. + * optimization: performance of FILL (and :INITIAL-ELEMENT) on + simple-base-strings and simple-bit-vectors is improved. * microoptimization: the compiler is better able to make use of the x86 LEA instruction for multiplication by constants. * bug fix: in some situations compiler did not report usage of generic arithmetic in (SPEED 3) policy. + * fixed some bugs revealed by Paul Dietz' test suite: + ** the RETURN clause in LOOP is now equivalent to DO (RETURN ...). + ** ROUND and FROUND now give the right answer when given very + small float arguments. + ** (FLOAT X) for X of type DOUBLE-FLOAT now returns X in all + circumstances. + ** optimizer for (EXPT X 0) did not work for X not of type FLOAT. + ** (GCD 0 ) returned . + ** LCM should return a non-negative integer. planned incompatible changes in 0.8.x: * (not done yet, but planned:) When the profiling interface settles
