+changes relative to sbcl-1.0.30:
+ * improvement: stack allocation is should now be possible in all nested
+ inlining cases: failure to stack allocate when equivalent code is manually
+ open coded is now considered a bug.
+ * new feature: experimental :EMIT-CFASL parameter to COMPILE-FILE can
+ be used to output toplevel compile-time effects into a separate .CFASL
+ file.
+ * optimization: multiplication and division of single- and double-floats
+ with constant +/-one has been optimized.
+ * optimization: multiplication of single- and double-floats floats by
+ constant two has been optimized.
+ * bug fix: moderately complex combinations of inline expansions could
+ be miscompiled if the result was declared to be dynamic extent.
+ * bug fix: in some cases no compiler note about failure to stack allocate
+ was emitted, even if the objects were in fact heap allocated.
+ * bug fix: minor violation of "otherwise inaccessible" rule for stack
+ allocation could cause objects users might reasonably expect to
+ be heap allocated to be stack allocated.
+ * bug fix: DESCRIBE signalled an error for generic functions under
+ certain circumstances. (reported by Leslie Polzer)

+changes in sbcl-1.0.30 relative to sbcl-1.0.29:
* minor incompatible change: SB-THREAD:JOIN-THREAD-ERROR-THREAD and
SB-THREAD:INTERRUPT-THREAD-ERROR-THREAD have been deprecated in favor
of SB-THREAD:THREAD-ERROR-THREAD.
values in other threads.
* new feature: SB-INTROSPECT:ALLOCATION-INFORMATION provides information
about object allocation.
- * optimization: more efficient complex float and real float operations
- on x86-64.
* optimization: division of a real float by a complex float is implemented
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),
and (EXPT -1.0d0 INTEGER) into an ODDP test. (thanks to Stas Boukarev and
Paul Khuong)
+ * optimization: compiler is smarter about delegating argument type checks to
+ callees.
+ * optimization: several character functions are now compiled somewhat more
+ efficiently. (reported by Lynn Quam)
+ * optimization: the compiler now derives simple types for LOAD-VALUE-FORMs.
* improvement: less unsafe constant folding in floating point arithmetic,
especially for mixed complex/real -float operations.
+ * optimization: constant double and single floats are stored in native
+ unboxed format on x86[-64].
+ * optimization: smarter code for arithmetic operations with constant floats,
+ complex floats, or integers on x86[-64].
+ * optimization: smarter code for conjugate/multiplication of float complexes
+ and abs/negate of floats on x86-64.
+ * optimization: more efficient complex float and real float operations on
+ x86-64.
* improvement: complex float division is slightly more stable.
* improvement: DESCRIBE output has been reworked to be easier to read and
contains more pertinent information.
* improvement: failure to provide requested stack allocation compiler notes
provided in all cases (requested stack allocation not happening without a
note being issued is now considered a bug.)
- * optimization: compiler is smarter about delegating argument type checks to
- callees.
* bug fix: SB-POSIX exports the documented types and functions
FILE-DESCRIPTOR and FILENAME, and also the corresponding -DESCRIPTOR
types. (reported by "abhi")
* bug fix: bogus undefined variable warnings from fopcompiled references to
global variables. (thanks to Lars Rune Nøstdal)
* bug fix: foreign function names should now appear in backtraces on
- FC6 as well. (reported by Tomasz Skutnik and obias Rautenkranz)
+ FC6 as well. (reported by Tomasz Skutnik and Tobias Rautenkranz)
* bug fix: SETF compiler macro documentation strings are not discarded
anymore.
* bug fix: GENTEMP is now unaffected by pretty printer dispatch table.
* 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)
