and SB-EXT:*SYSINIT-PATHNAME-FUNCTION*.
* enhancement: SB-EXT:MAKE-THREAD accepts an argument list designator for
the thunk, as a keyword argument, :arguments.
+ * enhancement: constraint propagation is simplified (and sped up) when
+ COMPILATION-SPEED > SPEED.
* optimization: extracting bits of a single-float on x86-64 has been
optimized. (lp#555201)
+ * optimization: MAP and MAP-INTO are more efficient for non-simple vectors,
+ when (> SPEED SPACE).
+ * optimization: local call trampolines (x86 and x86-64) are emitted
+ inline.
+ * optimization: implicit value cells for dynamic-extent closed-over bindings
+ on x86 and x86-64 can hold unboxed values as well.
+ * meta-optimization: improved compilation speed, especially for large
+ functions. (lp#792363 and lp#394206)
* bug fix: bound derivation for floating point operations is now more
careful about rounding possibly closing open bounds. (lp#793771)
* bug fix: SB-POSIX:SYSCALL-ERROR's argument is now optional. (accidental
* bug fix: FORMAT now handles floating point rounding correct, eg.
(format nil "~,1F" 0.01) => "0.0" instead of "0.01" as previously.
(lp#308961)
+ * bug fix: style warning during lambda-list introspection of generic
+ functions with both optional and key argments.
+ * bug fix: regalloc doesn't barf on unused TNs due to type-directed constant
+ folding. (lp#729765)
changes in sbcl-1.0.49 relative to sbcl-1.0.48:
* minor incompatible change: WITH-LOCKED-HASH-TABLE no longer disables
