changes relative to sbcl-1.1.7:
* notice: The implementation of MAP-ALLOCATED-OBJECTS (the heart of
ROOM, plus a few SB-INTROSPECT functions) has been completely
- rewritten, it may now exhibit different bugs than before.
+ rewritten; it may now exhibit different bugs than before.
* enhancement: RUN-PROGRAM supports a :DIRECTORY argument to set
the working directory of the spawned process.
(lp#791800) (patch by Matthias Benkard)
* enhancement: MAP-ALLOCATED-OBJECTS (the heart of ROOM) now walks the
heap in a manner similar to the GC rather than its previous ad-hoc
scheme, and is therefore no less and possibly more accurate.
+ * fixes and enhancements related to Unicode:
+ ** the character database information has been updated to Unicode 6.2;
+ ** support for canonical and compatibility decomposition of characters has
+ been added, along with support for primary composition;
+ ** support for Unicode normalization forms of strings (NFC, NFKC, NFD and
+ NFKD) has been included;
+ ** querying the character database for code points not defined by Unicode
+ gives less wrong answers (lp#1178038, reported by Ken Harris)
* bug fix: type derivation for LOG{AND,IOR,XOR} scales linearly instead
of quadratically with the size of the input in the worst case.
(lp#1096444)
threaded FreeBSD/x86-64.
* bug fix: some LOOP statements couldn't be compiled.
(lp#1178989)
+ * bug fix: sb-sequence:dosequence works on literal vectors.
+ * bug fix: errors in generic arithmetic show the assembly routine's
+ caller on x86 and x86-64. (lp#800343)
+ * bug fix: Compile-time type errors should never result in COMPILE-FILE
+ failure. (lp#943953)
+ * bug fix: Known bad local calls do not cause strange failures when
+ emitting or dumping code. (lp#504121)
+ * bug fix: Multiply-inlined structure constructor don't cause IR2-time
+ codegen errors: type checks are inserted as necessary. (lp#1177703)
+ * bug fix: Unsigned modular arithmetic is correctly converted into signed
+ modular arithemtic (mostly to exploit fixnum-width VOPs). (lp#1026634)
* optimization: faster ISQRT on fixnums and small bignums
* optimization: faster and smaller INTEGER-LENGTH on fixnums on x86-64.
* optimization: On x86-64, the number of multi-byte NOP instructions used
