Allow it to be built with lang/abcl. Remove build dependency on lang/sbcl
if bootstrapping.
Changes since version 1.5.7
New in version 2.0.7
* minor incompatible change: SB-THREAD:THREAD-OS-TID returns NIL
for a thread which has exited.
* minor incompatible change: OPEN no longer calls TRUENAME
implicitly on a string filespec prior to issuing an open()
system call.
* minor incompatible change: PATHNAME is no longer a STRUCTURE-OBJECT.
* documentation: HASH-FUNCTION is a function
designator. (#1888028, reported by Jacek Zlydach)
* bug fix: eliminated a potential garbage-collector deadlock when
linking with TCMalloc.
* bug fix: foreign threads (those not made by
SB-THREAD:MAKE-THREAD) can not crash with a "GC_PENDING, but
why?" error when returning back from Lisp into the foreign
caller.
* bug fix: sb-fasteval crashed trying to install a JIT-compiled
DEFSTRUCT accessor in a locked package.
* bug fix: removed misuse of putwc() which caused stdio streams to
drop characters.
* bug fix: the "maximum interrupt nesting depth exceeded" error
generated in the C runtime is significantly less likely to
occur.
* bug fix: sb-sprof should no longer segfault from calling
pthread_kill() on a nonexistent thread.
* bug fix: a portability issue arising from various build hosts
(#1886255, reported by Pierre Neidhart)
* bug fix: spurious compiler warnings from REDUCE with
:INITIAL-VALUE. (#1885515, reported by Michael South)
* bug fix: an inconsistency between class hierarchies and the type
system under some circumstances involving
redefinition. (#1886397, reported by Atilla Lendvai)
* bug fix: the USE-VALUE restart for OPEN on non-existent files is
more likely to function as expected. (#1886587)
* bug fix: various invalid inputs to ROTATE-BYTE no longer cause
compiler errors. (#1887164, #1888152)
* optimization: PPC64 on linux uses the __thread annotation on C
variables in preference to pthread_setspecific() and
pthread_getspecific().
New in version 2.0.6
* planned incompatible change: the defined symbols in the
Metaobject Protocol, currently accessible from both SB-MOP and
SB-PCL packages, will in a later release be no longer exported
from SB-PCL.
* platform support:
* better support for dynamic-extent on the SPARC architecture.
* bug fix for loading very large core files.
* bug fix for logior and logxor on PPC64.
* enhancement: EQUALP on structure instances uses code specialized
to each structure type, inlining comparison of non-pointer
slots.
* enhancement: some standard operators, such as
WITH-OUTPUT-TO-STRING and CHANGE-CLASS, have been adapted to use
dynamic-extent temporary objects, and so cons less garbage on
the heap.
* enhancement: read tables are more space- and speed efficient
* bug fix: stream conditions with dynamic-extent streams have the
stream replaced by a stub. (reported by Matt Kaufmann)
* bug fix: garbage collections triggered from foreign callbacks
crashed. (#1884403, reported by Andrew Kent)
* bug fix: compiler failure in compiling MAKE-LIST. (#1881349)
* bug fix: using the debugger from frames with calls to functions
with unsupplied optional arguments is less likely to cause heap
corruption. (#1883745)
New in version 2.0.5
* platform support:
* experimental support for ARM32 and ARM64 on OpenBSD
* better musl libc support. (#1768368, thanks to Eric Timmons)
* more correct use of futexes on 64-bit Linux. (#1876825,
reported by Ilya Perminov)
* restore building on current Solaris. (#1881393, thanks to
Shawn Ellis)
* enhancement: CMUCL-style START-BLOCK and END-BLOCK declarations
are now supported for block compiling forms at a sub-file
granularity.
* enhancement: IPv6 support in sb-bsd-sockets is enabled on Windows.
* minor change: *compile-print* now makes it more clear what block
compilation is actually doing. The default output is now
slightly more verbose as a result.
* bug fix: number keys in EQUALP hash tables are correctly
hashed. (#1878653, reported by Syll)
* bug fix: EQness is better preserved given partial sharing of
list contents in the file compiler. (#1583753, reported by Denis
Budyak)
* bug fix: the peephole pass neglected to preserve jump table
labels. (#1876485)
* bug fix: fix compiler crash in block compilation merging of
toplevel lambdas. (#1865336, reported by il71)
* bug fix: sb-introspect's function-lambda-arglist is better at
extracting default values of nested macro arguments. (#1876194)
* bug fix: RESTART-BIND's body is an implicit progn, and so does
not accept declarations. (#1876303, reported by Michal Herda)
* optimization: EQUAL hash tables with keys involving
structure-objects will have fewer systematic collisions.
New in version 2.0.4
* platform support:
* 32-bit RISC-V is now fully supported. Unlike other ports,
its backend is entirely shared with 64-bit RISC-V.
* native threads are now supported on RISC-V.
* fix and add some x86-64 vector instructions. (reported by
Shubhamkar Ayare)
* improve pointer representation on ppc64 for low-level
performance improvement.
* threads are more stable on big-endian ppc64
* enhancement: forward-referenced type tests can now be open-coded
by using block compilation. The result is that mutually
referential defstructs are now efficiently compiled in block
compilation mode, superseding a lighter mechanism that worked in
fewer contexts. However, that lighter mechanism has been
removed, so for now, users who want to efficiently compile
mutually referential defstructs must explicitly opt-in using
block compilation.
* bug fix: defstructs with empty initforms in the sbcl source are
now explicitly intiialized with NIL, as that is undefined
behavior under ANSI. This helps cross compilation hosts which do
not implicitly initialize empty initform slots to NIL. (Thanks
to Karsten Poeck)
* bug fix: backtracing through assembly routines now works
properly on RISC-V.
* bug fix: ASH no longer gets miscompiled in certain edge cases on RISC-V.
* bug fix: &MORE args have been slightly optimized and are more
correct on RISC-V.
* bug fix: unused local functions with &REST/&KEY/&OPTIONAL now
also issue a deletion note.
* bug fix: APPLY on a large list ("large" being in excess of 2k to
16k items depending on the platform) can no longer crash the
gencgc collector.
* bug fix: sb-concurrency FRLOCK algorithm has been corrected. (#1087955)
* bug fix: block compilation now respects inlining declarations
better (like CMUCL).
* optimization: hashing of structures with raw slots for EQUALP
hash tables has been improved.
New in version 2.0.3
* incompatible change: the external format now defaults to UTF-8
and is not affected by LANG. SB-EXT:*DEFAULT-EXTERNAL-FORMAT* is
now the only way to change it.
* minor incompatible change: the undocumented :EPHEMERAL argument
to MAKE-THREAD has been removed.
* minor incompatible change: DECLARE type testing of structure
types when the SAFETY optimization quality is less than SPEED
(but greater than 0) is precise, rather than merely testing that
an object is a (general) STRUCTURE-OBJECT.
* platform support
* respect sunos platform assembler flag handling
* riscv architecture can be detected during the build
* enabled the sb-dynamic-core feature on riscv, sparc, and
made it unconditional everywhere
* cheneygc is an option for arm and arm64
* enhancement: the installed sbcl executable tree can be renamed
or moved without risk of incorrectly referencing a '.core' file
from an obsolete path. (#666086)
* optimization: transform (values-list (list one-item)) to (values
one-item) as multiple items were already recognized.
New in version 2.0.2
* new feature: CMUCL-style block compilation support has been
added, allowing whole program optimization. It has been
documented in a new section of the manual entitled "Advanced
Compiler Use and Efficiency Hints". In particular, users of
block compilation will find a large speedup for numerical code,
as functions which call or return floating point values will
keep everything unboxed.
* bug fix: in CHANGE-CLASS, handle non-standard
slot-value-using-class for :INSTANCE and :CLASS slots
better. (reported by Shinmera on #sbcl)
* bug fix: REMHASH in an EQUAL or EQUALP hash-table works
correctly on a key for which EQUAL (respectively EQUALP) is
reduced to EQ. (#1865094)
* bug fix: do not emit a warning for DEFCLASS slots with
mismatched :TYPE and :INITFORM when the class has a non-standard
metaclass.
* bug fix: DISASSEMBLE on SPARC is less likely to spuriously
annotate code sequences as error traps.
New in version 2.0.1
* minor incompatible change: some symbols have been removed from
*FEATURES* based on a determination of which should be
impermissible to examine via #+ and #- reader macros in
user-written code.
* optimization: DEFSTRUCT copiers including COPY-STRUCTURE are
able to stack-allocate the result when declared dynamic-extent.
* bug fix: loop analysis code more robust. In particular, loop
nesting depth is computed more accurately, improving the
register allocation around loops.
New in version 2.0.0
* minor incompatible change: heap relocation now works on
Windows. Since this feature now works on all platforms, it is
enabled unconditionally and the :RELOCATABLE-HEAP symbol no
longer appears on *FEATURES* in any builds. (Thanks to Luís
Borges de Oliveira)
* enhancement: malformed type specifiers and occurrences of
deprecated types in :TYPE initargs of DEFCLASS and
DEFINE-CONDITION slot specifications are detected and result in
compile-time errors and warnings respectively.
* enhancement: parallel contrib building, controlled by
SBCL_MAKE_JOBS=-jX the same as for the C runtime.
* bug fix: add a walker template for WITH-SOURCE-FORM.
* bug fix: start the summary of a compilation unit on a fresh
line. (Thanks to Zach Beane)
* bug fix: on Windows, PARSE-NATIVE-NAMESTRING produces an
absolute directory when parsing a bare drive name and
:AS-DIRECTORY is specified. (Thanks to Luís Borges de Oliveira)
* bug fix: on RISCV, the runtime is linked with libz if the core
compression feature is requested. (Thanks to Andreas Schwab)
* bug fix: ADJOIN using an EQL test and a KEY function only
transforms into an EQ test if the key function returns values
for which EQ and EQL are guaranteed to be the same.
* optimizations:
* the instruction sequence for multiple-value calls is more
efficient on x86-64.
* the direction flag is now unused on x86 and x86-64 when
handling an unknown number of return values. (Thanks to
Fanael Linithien)
* the x86-64 backend is better able to use memory operands for
arithmetic operations.
* compilation of TYPECASE to a jump table is enabled when all
the types being tested are frozen.
* compilation of CASE and ECASE into a jump table has been
implemented on 32- and 64-bit powerpc platforms.
* the implementation of Unicode normalization has been sped up.
* pretty-printing dispatch on conses is faster, particularly
with the standard pretty-print dispatch table. Deeply-nested
forms should also pretty-print faster.
New in version 1.5.9
* platform support:
* a message intended to be more helpful will be displayed for
an mmap failure on OpenBSD.
* the soft-float ABI on ARM32 is better supported, in
particular in returning double floats from calls into C.
* optimizations:
* CASE and ECASE with symbols as keys may be optimized into a
vector lookup if all result forms are quoted or
self-evaluating objects.
* CASE and ECASE can be optimized into a jump table on the
x86[-64] backends with arbitrary result forms provided that
the clause keys are either all fixnums, all characters, or
all symbols.
* a number of forms are converted to use CASE in circumstances
where that makes sense, including calls to POSITION, MEMQ
and MEMBER, and TYPECASE where the types are MEMBER/EQL
types.
* POSITION of a variable symbol in a constant sequence of
symbols is converted to CASE and thence to a jump table.
* TYPECASE of a variable where the clauses are member types is
converted to CASE and thence to a jump table.
* a number of slow instructions are no longer used on x86 and
x86-64 machines. (Thanks to Fanael Linithien)
* the compiler is better at tracking the implications of
branches after EQ and EQL tests.
* parsing &KEY lists is slightly less register-intensive.
* a pattern-based peephole optimizer pass has been added,
running some simple transformations on the x86-64 backend.
* enhancements: more thorough compile-time type checking of
various initforms (defclass, &key, defstruct).
* bug fix: unions of complicated CONS types are less likely to
cause an infinite loop. (#1799719)
* bug fix: DESCRIBE on functions not named by extended function
designators no longer signals a type error. (#1850531, reported
by Michal Herda)
New in version 1.5.8
* platform support:
* support for Mac OS X Catalina
* improvements in interoperability with C code compiled with
memory sanitization options
* libsbcl.so links to zlib when sb-core-compression is
enabled. (#1845763, thanks to Juan M. Bello-Rivas)
* workarounds for BSD issues around mmap() and
pthread_attr_setstack(). (#1845936) support SSE for bzero if
available on OpenBSD
* optimizations:
* improved type understanding and translations for division
operators (including TRUNCATE, GCD, LCM).
* sequential comparisons and branches can elide intermediate
comparisons. (#1847284)
* convert EQUAL and EQUALP to EQL if either of the arguments
is a type for which the structural equality predicate is
identical to the simpler equality check. (#1848583)
* internal operators implementing string comparisons produce
simpler-to-consume values. (#1848776)
* bug fix: inspecting adjustable arrays and vectors with fill
pointers works better. (#1846191, reported by Yves Pagani)
