changes in sbcl-2.3.3 relative to sbcl-2.3.2:
* enhancement: LET-bound anonymous closures declared dynamic extent can now
be stack allocated, just like closures bound with FLET or
LABELS. Otherwise-inaccessible closure subparts of objects declared
dynamic extent can now also be stack allocated
* optimization: many standard CL functions which take functional arguments
will automatically stack allocate any downward funarg closures.
* optimization: better arithmetic between signed and unsigned words on arm64.
* optimization: reduce consing when doing arithmetic resulting in small (3
words or fewer) bignums.
* bug fix: miscompilation of some additions of signed and unsigned words on
x86-64. (lp#2008673)
* bug fix: loading the SB-SIMPLE-STREAMS contrib no longer incompatibly
overwrites CL:OPEN's function type. (lp#2008811)
* bug fix: implement the special-case automatic function definition for
PCL's slot accessor functions in the SB-EVAL interpreter. (lp#2008922,
reported by Jonathan Braud)
* bug fix: allow the build to succeed under SBCLs older than 2.0.0 in the
event that the host emits STYLE-WARNINGs while compiling the
cross-compiler. (lp#2009493, reported by Kirill)
* bug fix: restore compilation on ARM64 with OpenBSD. (lp#2009585, reported
by okflo)
* bug fix: compiling a HANDLER-BIND with an function undefined at
compile-time produces a compile-time STYLE-WARNING. (lp2010176)
* bug fix: support files bigger than 4GB on ARM64/Linux, *BSD. (lp#2011453,
reported by Yan)
* bug fix: it is now possible to run sb-simd tests on systems without AVX2.
(lp#2011923, thanks to Sergio Durigan Junior)
* bug fix: miscompilation of some conditional moves. (lp#2012312, reported
by Patrick Poitras)
* bug fix: SB-GMP no longer signals a TYPE-ERROR when raising a ratio base
to a negative integer exponent. (lp#2012577, thanks to Ari Projansky)
* bug fix: warn the user when they have declared a structure or
standard-object slot of :TYPE NIL.
