* 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.
+ * new feature: minimal runtime/compiler intrastructure support for SSE
+ SIMD values, as SB-EXT:SIMD-PACK. Enabled on x86-64 via the build-time
+ feature :sb-simd-pack. This should enable intrinsics extensions as
+ libraries, without patching SBCL itself. Thanks to Alexander Gavrilov
+ for maintaining a branch for so long.
* enhancement: RUN-PROGRAM supports a :DIRECTORY argument to set
the working directory of the spawned process.
(lp#791800) (patch by Matthias Benkard)
** querying the character database for code points not defined by Unicode
gives less wrong answers (lp#1178038, reported by Ken Harris)
* enhancement: print intermediate evaluation results for some ASSERTed
- expressions. (lp#789497)
+ expressions. (lp#789497) (patch by Alexandra Barchunova)
+ * enhancement: x86-64 disassemblies are annotated with unboxed constant
+ values when there are references to (RIP-relative) unboxed constants.
* 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)
rational values.
* optimization: quasiquote expressions now perform more constant folding,
instead of consing equal lists at runtime. (lp#1026439)
+ * optimization: local call analysis of inlined higher-order function
+ should converge more quickly, resulting in better code for complex
+ functions.
+ * optimization: On x86-64, medium (word-sized but wider than 32 bits)
+ integer constants are handled more cleverly, especially when they
+ can be represented as sign-extended (signed-byte 32). (Based on a
+ patch by Douglas Katzman)
+ * optimization: IF/IF conversion should reliably result in sane code
+ when (some of) the results of the inner IF are always false or
+ always true.
changes in sbcl-1.1.7 relative to sbcl-1.1.6:
* enhancement: TRACE :PRINT-ALL handles multiple-valued forms.
