sbcl-2.2.5
d72c9e2e · ·changes in sbcl-2.2.5 relative to sbcl-2.2.4: * minor incompatible change: SB-EXT:*DERIVE-FUNCTION-TYPES* being NIL now means that function calls will strictly only use type information from proclaimed ftypes. The previous behavior (still the default) of using derived type information from the same file is specified with :SAME-FILE. (lp#1393302) * minor incompatible change: RENAME-FILE now overwrites the target file on Windows too, making its behaviour consistent with other platforms. * minor incompatible change: inlining of local function is inhibited if policy DEBUG = 3. * platform support: ** single-stepping is now supported on 64-bit PowerPC platforms. (thanks to Thomas Fitzsimmons) ** the :SB-LINKABLE-RUNTIME feature is now supported on 32-bit and 64-bit PowerPC platforms. (thanks to Thomas Fitzsimmons) * optimization: improved type derivation of REDUCE with some known reducing functions. * enhancement: debug source locations now work correctly for top level forms with policy DEBUG = 1, as well as for block compiled files. * enhancement: TRACE now supports tracing macro functions, compiler-macro functions, individual methods and local functions. See the user manual for more details. (lp#375314) * bug fix: fix integer comparisons on x86-64 and arm64 (lp#1971088, reported by Guillaume LE VAILLANT) * bug fix: coverage instrumentation behaves correctly with respect to non-local exits. * bug fix: ftype proclamations now take effect immediately during block compilation. * bug fix: block compilation of top-level closures now work. (lp#1931730, reported by Sean Maher) * bug fix: streams opened from RUN-PROGRAM but left unclosed because of a non-local exit no longer cause unrelated streams to be closed later. -
sbcl-2.2.4
b0f6cecc · ·changes in sbcl-2.2.4 relative to sbcl-2.2.3: * enhancement: better constraint propagation in the compiler. Specifically, the compiler can now derive the type of X in control flow join situations such as (LAMBDA (X) (ECASE (1 ...) (2 ...)) X) or (LAMBDA (X) (ETYPECASE (INTEGER ...) (SYMBOL ...)) X) instead of forgetting all information about X after the E(TYPE)CASE. * optimization: inlined functions enclosed in local macro definitions no longer save their entire lexical environment, reducing unnecessary memory retention. * optimization: faster (< integer fixnum) comparisons (ARM64 and x86-64). * platform support: ** RUN-PROGRAM is faster on Linux and FreeBSD if close_range(2) is available. * bug fix: block compilation now interacts more correctly with the creation of new packages. * bug fix: internal compiler error in array reference optimizer.

cb5e4205 · ·changes in sbcl-2.2.3 relative to sbcl-2.2.2: * minor incompatible change: SB-THREAD:MUTEX-OWNER may return :THREAD-DEAD if the apparent owner either exited nearly instantly after releasing the mutex (and is not now the owner), or died and never released it. * minor incompatible change: building the system with the simple semi-space copying collector is no longer supported. * minor incompatible change: support for PPC/Darwin has been removed. * platform support: ** fix regressions in threads on RISC-V.

sbcl-2.2.2
5a98c580 · ·changes in sbcl-2.2.2 relative to sbcl-2.2.1: * platform support: ** all architectures now share the coverage mark instrumentation implementation, meaning that performance now equals what had been implemented only on x86 architectures. ** fixed a performance regression on x86-64 from changes in AVX2 register handling. (lp#1960081, reported by Michael Kappert) ** fixed a garbage collection bug on ppc64 manifesting in occasional corruption on threaded programs.

(thanks to Felix Lange) ** faster function call sequence on arm64. ** the built-in buffer size for file streams is increased to 8KB. * enhancement: provide a restart for method lambda list mismatches that fmakunbounds the generic function. * enhancement: provide a USE-VALUE restart around type errors signalled from (SETF SLOT-VALUE). * enhancement: when UPDATE-INSTANCE-FOR-DIFFERENT-CLASS (or -REDEFINED-) undergoes a non-local exit, restore the instance to its original state. (thanks to Michał phoe Herda) * enhancement: the :SYNCHRONIZED keyword argument to MAKE-HASH-TABLE is no longer experimental. * bug fix: fix an erroneous compiler tranform for (EXPT SINGLE-FLOAT INTEGER). (lp#1958061, thanks to Vasily Postnicov) * bug fix: disassembly of closures is more likely to show the relevant code if more than one closure closes over the same environment. (lp#1956870, reported by Michał phoe Herda) * bug fix: RUN-PROGRAM with :IF-EXISTS :APPEND no longer signals an error if the output does not exist. (lp#1958569, thanks to Ingo Krabbe) * optimization: reorder basic blocks to have loop code fall through more often. (thanks to Hayley Patton) * optimization: sequences larger than the buffer size are written to streams without going through a buffering stage. (reported by Philipp Marek) -

sbcl-2.1.11
d76ad2a9 · ·changes in sbcl-2.1.11 relative to sbcl-2.1.10: * minor incompatible change: *COMPILE-PRINT* now defaults to NIL. T gives the old behavior of echoing top level forms. Users who want to see a report of the phases of compilation can use *COMPILE-PROGRESS* and the corresponding COMPILE-FILE :PROGRESS argument. * optimization: The compiler assignment-converts functions much more aggressively; local or non-entry block-compiled functions which always return to the same place are automatically converted into the equivalent loop or goto control structures. * enhancement: on x86-64 and ppc64 platforms, the system uses inline instructions rather than page protection to implement a store barrier for the garbage collector. * enhancement: improved reporting of code deletion notes. * platform support: ** unbound-variable restarts for amd64 are now supported. ** bug fix: single-floats to foreign functions on 32-bit ARMel.

73c8c9f2 · ·changes in sbcl-2.1.10 relative to sbcl-2.1.9: * incompatible change: simd-pack without a specific element-type is no longer treated as containing integers. A type must be supplied for VOPs to work on such values. * minor incompatible change: the list form of the FUNCTION type specifier does not allow * as any argument type, but does allow * as a placeholder for wholly unspecified arguments when specifying the value(s) type. * minor incompatible change: the default (Lisp) toplevel option parser throws an error if it encounters an option which was intended to be used and removed by the C runtime. (lp#1945081, reported by Luke Gorrie) * new feature: there is now a defined interface for defining foreign callable functions, which can be used for passing callbacks to foreign functions or for calling Lisp code from the foreign world as a shared library (preliminary support).
