+changes relative to sbcl-1.0.52:
+ * enhancement: on 64-bit targets, in src/compiler/generic/early-vm.lisp,
+ the parameter n-fixnum-tag-bits may now vary from 1 (fixnum =
+ (signed-byte 63)) to 3 (fixnum = (signed-byte 61)) at build-time.
+ * enhancement: SB-EXT:WAIT-FOR allows waiting for arbitrary events.
+ * minor(?) incompatible(?) change: The default fixnum width on 64-bit
+ targets is now 63 bits (up from 61).
+ * enhancement: DESCRIBE now reports a lambda-list and source location
+ for complext setf-expanders.
+ * bug fix: PUSH, PUSHNEW, POP, REMF, INCF, DECF, DEFINE-MODIFY-MACRO,
+ GETF, LOGBITP, LDB, and MASK-FIELD now arrange for non-primary values
+ of multiple-valued places to be set to NIL, instead of signalling an
+ error (per a careful reading of CLHS 5.1.2.3).
+ * bug fix: floating-point traps now work on darwin/x86 and /x86-64.
+ * bug fix: repair crash in x86oid darwin signal handling emulation
+ when built with certain compilers.
+ * bug fix: SB-ROTATE-BYTE misrotated to the right when using constant
+ rotation arguments on x86-64. (lp#882151)
+ * bug fix: low-level control flow optimisations could result in bogus
+ code in functions with tail and non-tail calls to local functions on
+ x86oids. (lp#883500)
+ * bug fix: on SPARC/:sb-unicode, avoid crashing the assembler by trying
+ to emit literal characters > (code-char 4095), for comparisons with
+ constant characters.
+ * bug fix: ROOM reported only the low 32 bits of dynamic space usage
+ on 64 bit platforms. (lp#881445)
+ * bug fix: DELETE-FILE did not MERGE-PATHNAMES, making it possible to
+ delete the wrong file when using relative pathnames. (lp#882877)
+ * bug fix: optimized SEARCH of vectors-on-vectors mishandled zero-length
+ sequences and :KEY NIL.
+
+changes in sbcl-1.0.52 relative to sbcl-1.0.51:
* enhancement: ASDF has been updated to version 2.017.
* enhancement: the --core command line option now accepts binaries with
an embedded core.
+ * enhancement: when built with :sb-core-compression, core files (regular
+ or executable) can be compressed with zlib. Use the :COMPRESSION
+ argument to SAVE-LISP-AND-DIE to specify a compression level.
+ * enhancement: --[no-]merge-core-pages determines whether the runtime
+ hints the operating system that identical core pages between SBCL
+ processes should share the same physical memory. Default is to only
+ enable this for compressed cores.
* optimization: SLEEP no longer conses.
* optimization: *PRINT-PRETTY* no longer slows down printing of strings
or bit-vectors when using the standard pretty-print dispatch table.
(lp#738464)
* bug fix: compiler-errors causes by MEMBER types in conjunction with with
AREF, CHAR, etc. (lp#826971)
- * bug fix: compiler-errors causes by integer arguments with composed of multiple
- ranges to ARRAY-IN-BOUNDS-P. (lp#826970)
+ * bug fix: compiler-errors causes by integer arguments with composed of
+ multiple ranges to ARRAY-IN-BOUNDS-P. (lp#826970)
* bug fix: ,@ and ,. now signal a read-time error for certain non-list
expressions. (lp#770184)
+ * bug fix: complex single float literals are correctly aligned when used
+ as arguments of arithmetic operators.
+ * bug fix: on 32-bit platforms, rounding of double floats larger than a
+ fixnum is correct. (reported by Peter Keller)
+ * bug fix: stray FD-HANDLERs are no longer left lying around after unwinds
+ from RUN-PROGRAM. (lp#840190, reported by Dominic Pearson; fix from Max
+ Mikhanosha)
+ * bug fix: redefining classes such that slots with custom allocation are
+ added or removed works again.
changes in sbcl-1.0.51 relative to sbcl-1.0.50:
* minor incompatible change: SB-BSD-SOCKET socket streams no longer
