with a specialised code sequence.
* optimization: MAKE-INSTANCE with non-constant class-argument but constant
keywords is an order of magnitude faster.
- * optimization: MAKE-INSTANCE with constant keyword arguments is somewhat
- faster for non-standard metaclass classes as long as there are no methods
- additional on MAKE-INSTANCE and initialization arguments can be validated
- at compile-time.
+ * optimization: MAKE-INSTANCE with constant keyword arguments is x2-4 faster
+ in the presence of :AROUND or non-standard primary INITIALIZE-INSTANCE
+ methods, and similarly for non-standard metaclass classes as long as there
+ are no methods additional on MAKE-INSTANCE.
* optimization: more efficient type-checks for FIXNUMs when the value
is known to be a signed word on x86 and x86-64.
* optimization: compiler now optimizes (EXPT -1 INTEGER), (EXPT -1.0 INTEGER),
* bug fix: SLEEP accepts large integer arguments, truncating them to
SIGNED-WORD on the assumption that sleeping for 68 years is sufficient
for anyone. (reported by Leslie Polzer, thanks to Stas Boukarev)
+ * bug fix: compiler notes for expensive slot type checks could be emitted
+ at runtime MAKE-INSTANCE calls. (reported by Samium Gromoff)
changes in sbcl-1.0.29 relative to 1.0.28:
* IMPORTANT: bug database has moved from the BUGS file to Launchpad
