- Log -----------------------------------------------------------------
changes in sbcl-2.1.1 relative to sbcl-2.1.0:
  * platform support:
    ** restore non-threaded NetBSD builds;
    ** adjust how the finalizer thread is started; (lp#1906571, lp#1907872)
    ** fix the encoding of PEXTR on x86-64;
  * minor incompatible change: emit warnings for list iteration forms when the
    object being iterated over is known not to be a list.  (lp#1908819,
    reported by Michael Fiano)
  * bug fix: detect 2 or 1 as an invalid number of arguments passed to
    optimized slot writing or reading effective method respectively.
    (lp#1909659, reported by Michal Herda)
  * bug fix: division by zero errors were in some cases not being signalled.
    (lp#1910098, reported by il71)
  * bug fix: erroneous coercions in the type system could lose precision.
    (lp#1910294)
  * bug fix: literal (read-time evaluated) NaNs in source code no longer cause
    compiler crashes.  (lp#1909881, reported by Michal Herda)
  * bug fix: detect more erroneous syntax in method bodies.  (lp#1912362,
    reported by Paul M. Rodriguez)
  * optimization: the compiler's understanding of EXPT is improved, reducing
    the introduction of COMPLEX types.  (lp#1908830, reported by Michael Fiano)
  * optimization: the compiler is better at computing numeric contagion when
    (COMPLEX FLOAT) types are involved.
  * micro-optimizations:
    ** moving from slightly-bigger-than-fixnum ranges is more efficient on x86-64;
    ** encode character comparisons with smaller operands on x86-64;
    ** truncating (and related operations) on floats can be inlined in more
       cases on 64-bit platforms;
    ** rounding can use specialized instructions on ARM64 and on x86-64 when
       SSE4 is available;
