This is known to affect + 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 + for code alignment is now always minimal. + * optimization: On 64-bit targets, the compiler generates much faster + code for type checks for types known at compile time that are smaller + than (SIGNED-BYTE 64) or (UNSIGNED-BYTE 64) and larger than FIXNUM, and + their COMPLEX variants. + * optimization: On x86 targets, more uses of ALIEN-FUNCALL during cross + compilation now inline the INVOKE-WITH-SAVED-FP-AND-PC dance. + * optimization: ROOM no longer conses so egregiously on non-x86oid + systems. + +changes in sbcl-1.1.7 relative to sbcl-1.1.6: + * enhancement: TRACE :PRINT-ALL handles multiple-valued forms. + (lp#457053) + * bug fix: :allocation slot option works for condition slots + (lp#1049404) + * bug fix: redefining conditions does not lead to multiple evaluations of + hairy slot initfunctions anymore (lp#1164969) + * bug fix: CLASS-DIRECT-DEFAULT-INITARGS now works for condition classes + (lp#1164970) + * bug fix: function constants now work as initforms and default initarg + values of conditions (lp#539517) + * bug fix: svref/(setf svref) on symbol macros don't crash the compiler + anymore. (Minimal test case provided by James M. Lawrence on sbcl-devel) + * bug fix: no more bogus ## references when pretty printing backquoted + forms with non-trivial structure sharing. (lp#1161218) + * bug fix: Don't signal an error on (setf (documentation nil 'function) + "doc"). Signal a style-warning instead when trying to set documentation + of NIL for all other documentation types. (Reported by Zach + Beane; regression since 2e52fa05.) + * bug fix: modular arithmetic involving large constants and conditionals + should no longer result in spurious dead code elimination. (Reported by + Eric Marsden). + * bug fix: our mach exception handler can seemingly called very early in + the program execution process on OS X 10.8.0. Try and handle that case + robustly, without potentially leaking mach ports too much. + * optimization: LOGBITP and LOGTEST optimizations from x86 ported to x86_64. + +changes in sbcl-1.1.6 relative to sbcl-1.1.5: + * enhancement: the continuable error when defknown-ing over extant + fndb entries can be ignored by passing :overwrite-fndb-silently t + as a keyword argument to sb-c:defknown (after attributes). Useful + to allow defknown to be re-loaded. Use with :allow-other-keys t + for backward compatibility. + * optimization: compiler is much faster in compiling SVREF and (SETF SVREF) + forms. * bug fix: Prevent a make-array transform from modifying source forms causing problems for inlined code.
