-changes relative to sbcl-1.0.42
+changes relative to sbcl-1.0.44:
+ * bug fix: when SPEED > SPACE compiling CONCATENATE 'STRING with constant
+ long string arguments slowed the compiler down to a crawl.
+
+changes in sbcl-1.0.44 relative to sbcl-1.0.43:
+ * enhancement: RUN-PROGRAM accepts :EXTERNAL-FORMAT argument to select the
+ external-format for its :INPUT, :OUTPUT, AND :ERROR :STREAMs.
+ * enhancement: ALLOCATION-INFORMATION also provides the page the object
+ resides on.
+ * enhancement: default dynamic-space size can be configured at build-time
+ without touching source, using the --dynamic-space-size argument to make.sh.
+ * enhancement: DESCRIBE recognizes symbols naming optimization policy
+ qualities, and mentions ALWAYS-BOUND declarations.
+ * enhancement: ATOMIC-INCF now supports AREF of (SIMPLE-ARRAY SB-EXT:WORD (*))
+ as a place.
+ * enhancement: ASDF has been updated to 2.009.
+ * enhancement: the system detects known type-erros in calls better,
+ signalling a full warning about violated proclaimed FTYPEs and violations
+ of derived FTYPEs within the same file, including self-calls.
+ * enhancement: new function: SB-EXT:DELETE-DIRECTORY is now provided.
+ * optimization: constant-folding exploits numeric and character types, in
+ addition member types.
+ * optimization: numeric, character and member types that are inhabited by
+ exactly one value are tested with EQL.
+ * optimization: more conditional branches are eliminated during IR1.
+ Branches are simplified before performing if/if-conversion, and simple
+ equivalent branches (that only read the same constant or variable) are
+ merged.
+ * improvements to the Windows port:
+ ** change: canonical unparsing form for pathname namestrings now uses / as
+ directory separator. NATIVE-NAMESTRING still uses \ as the separator.
+ ** bug fix: stackoverwriting due to incorrect usage of PeekConsoleInput
+ on Windows. (thanks to Kalyanov Dmitry)
+ ** bug fix: build now works on cygwin with GCC 4.x installed. (thanks to
+ Kalyanov Dmitry)
+ ** bug fix: run-sbcl.sh now works on Cygwin. (thanks to Kalyanov Dmitry)
+ * bug fix: compiler failed to derive the result-type of MAKE-ARRAY as
+ (AND VECTOR (NOT SIMPLE-ARRAY)) when appropriate. (lp#309130)
+ * bug fix: (THE (VALUES ...)) in LOAD-TIME-VALUE caused a compiler-error.
+ (lp#646796)
+ * bug fix: interrupts arriving during CL:OPEN caused an error.
+ * bug fix: overeager character buffering could cause input to block
+ spuriously when reading from a pipe (lp#643686)
+ * bug fix: more efficient timer expiry should avoid starvation on systems
+ where number of SIGALRMs per second is restricted. (lp#375515)
+ * bug fix: non-unicode builds no longer fail (broken since 1.0.36.15).
+ * bug fix: compile-times no longer scale linearly with the size of
+ quoted lists in source-code. (lp#654289)
+ * bug fix: better errors for unknown external-formats in OPEN. (lp#561974)
+ * bug fix: DEBUG>SPEED no longer degrades ALIEN-FUNCALL performance quite
+ so badly. (lp#654485)
+ * bug fix: SB-INTROSPECT:FIND-DEFINITION-SOURCES-BY-NAME no longer signals
+ an error for eg. STRUCTURE. (lp#458015)
+ * bug fix: LOOP WITH NIL = ... signalled an unused variable style-warning.
+ (lp#613871, thanks to Roman Marynchak)
+ * bug fix: more reliable &REST list type derivation. (lp#655203)
+ * bug fix: PPRINT-LOGICAL-BLOCK multiply-evaluated :PER-LINE-PREFIX,
+ and issued pointles code-deletion notes for it, :PREFIX, and :SUFFIX.
+ * bug fix: the compiler didn't utilize the proclaimed ftype for functions
+ also declared NOTINLINE. (lp#655581)
+ * bug fix: the compiler could attempt to emit constant left shifts of
+ greater value than n-word-bits. (lp#309063)
+ * bug fix: (SETF SYMBOL-FUNCTION) and (SETF FDEFINITION) clear derived
+ type information for the function being set. (lp#659220)
+ * bug fix: the system used to signal bogus STYLE-WARNINGs when functions
+ containing self-calls were recompiled with a new signature, and failed
+ to warn when a self-call using the old signature was left in. (lp#655126)
+ * bug fix: incorrect FILE-POSITION on streams opened using :EXTERNAL-FORMAT
+ :DEFAULT when the default external had character size other than 8 bits.
+ (lp#657183)
+ * bug fix: derived types of functions in the same file were implicitly
+ trusted, leading to potential heap corruption when those function were
+ defined incompatibly. (lp#657499)
+ * bug fix: existing ASDF source registries are ignored when building
+ contribs (lp#659105)
+ * bug fix: short-form DEFSETF checks that the second argument is a symbol
+ (lp#655824, thanks to Roman Marynchak)
+ * bug fix: (SETF MACRO-FUNCTION) clobbered macro-definitions before
+ package-lock violation was detected. (lp#660752)
+ * bug fix: the system can store different docstrings for a single function
+ under different names. (lp#661631, regression from 1.0.29.24)
+ * bug fix: source-locations of DEFGENERIC forms weren't getting recorded
+ properly. (lp#384801)
+ * bug fix: (COERCE X '(SIMPLE-VECTOR 5)) and similar coercions to vectors
+ of specified length could confuse the type derivation in unsafe code.
+ (lp#655872)
+ * bug fix: SB-POSIX:FORK now signals an error if an attempt to
+ fork with multiple Lisp threads running is made on every platform,
+ not just Darwin. (lp#451111)
+ * bug fix: SB-BSD-SOCKETS and SB-SIMPLE-STREAMS could leave stale finalizers
+ around when core was saved, which could cause undefined behaviour when the
+ core was reified.
+ * bug fix: Allow UNTRACE of functions that are no longer defined
+ (lp#667657, thanks to Attila Lendvai)
+ * bug fix: MAKE-ARRAY calls with invalid keyword argument lists now signal a
+ compile-time warning (lp#664373, thanks to Stas Boukarev)
+
+changes in sbcl-1.0.43 relative to sbcl-1.0.42:
* incompatible change: FD-STREAMS no longer participate in the serve-event
event-loop by default. (lp#316072)
