(lp#728247) + * enhancement: support building under new linker handling of syscalls under + NetBSD. (thanks to Robert Swindells) + * bug fix: undefined function errors are now properly reported on PPC and MIPS. + (regression since 1.1.9) + * bug fix: (funcall (function X junk)) didn't causes an error when X had a + compiler macro. (thanks to Douglas Katzman). + * bug fix: signal a warning when defining a setf-function when a + setf-expander is already present.

(reported by Jan Moringen) + +changes in sbcl-1.1.10 relative to sbcl-1.1.9: + * enhancement: ASDF has been updated to 3.0.2. + * optimization: stack frames are packed more efficiently on x86oids, which + ought to reduce the frequency of Methuselahn conservative references (it + certainly helps with gc.impure.lisp / BUG-936304 on x86). + * optimization: on x86 and x86-64, integer negation forms like (- x) are now + recognized in modular arithmetic contexts, and compile to native negate, + rather than going through bignums only to keep the low bits. + * bug fix: Compiling potential modularic arithmetic forms does not cause type + errors when some integer types lack lower or upper bounds. (lp#1199127) + * bug fix: Non-trivial modular arithmetic forms are always cut to the right + bitwidth before being used in a non-modular context. (lp#1199428) + * bug fix: Multiple catch/unwind blocks in a single function are now + allocated in the right stack order on win32. (lp#1072739) + +changes in sbcl-1.1.9 relative to sbcl-1.1.8: + * new feature: the contrib SB-GMP links with libgmp at runtime to speed + up arithmetic on bignums and ratios. (contributed by Stephan Frank) + * enhancement: disassemble now annotates some previously missing static functions, like LENGTH. - * bug fix: problems with NCONC type derivation (reported by Jerry James). + * enhancement: clean.sh now also cleans doc/internals. + * enhancement: SB-EXT:PRINT-SYMBOL-WITH-PREFIX can be used within ~// to + print a symbol with a package prefix. + * enhancement: The debugger and backtracing are more robust against buggy + PRINT-OBJECT methods. * optimization: calls to static functions on x86-64 use less instructions. * optimization: compute encode-universal-time at compile time when possible. * optimization: when referencing internal functions as #'x, don't go through an indirect fdefn structure. * optimization: SLEEP doesn't cons on non-immediate floats and on ratios. - + * optimization: (mod fixnum) type-checks are performed using one unsigned + comparison, instead of two. + * optimization: enable more modular arithmetic transforms in the presence of + conditionals. + * optimization: bitwise OR forms can now trigger modular arithmetic as well, + when the result is known to be negative. + * optimization: recognize more cases of useless LOGAND/LOGIOR with constants. + * optimization: comparisons between rationals and constant floats or between + integers and constant ratios are now converted to rationals/integers at + compile time. + * optimization: Smaller and faster DOUBLE-FLOAT-LOW-BITS on x86-64. + * bug fix: problems with NCONC type derivation (reported by Jerry James). + * bug fix: EXPT type derivation no longer constructs bogus floating-point + types. (reported by Vsevolod Dyomkin) + * bug fix: sb-bsd-sockets has correct declaration of the canonname field of + addrinfo. (lp#1187041, patch by Jerry James) + * bug fix: uninitialized type-error conditions can now be printed. + (lp#1184586) + * bug fix: tests for sb-bsd-sockets no longer use a predefined port for + listening, allowing several tests to run in parallel. + * bug fix: during disassembly to *COMPILER-TRACE-OUTPUT* instruction + prefixes as used on x86 and x86-64 no longer sometimes print incorrectly. + (lp#1085729) + * bug fix: Specialised SIMD-PACK types can be negated. + * bug fix: Modular arithmetic is more robust.

(lp#1185668) + * bug fix: backtrace printer no longer tries to create very large lists when + the arg-count register is clobberred by other code. (lp#1192929) + * bug fix: x86 should never signal an FP exception while boxing an FP value, + a situation that lands us into ldb. + changes in sbcl-1.1.8 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
