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.
(lp#1950080, reported by Sebastien Villemot)
** bug fix: opening files with names containing non-ASCII characters on
Windows works better. (reported by Nikolay)
** bug fix: use fp_xsave to access the floating point flags and control
word in Haiku signal contexts. (Thanks to Al Hoang)
** bug fix: complex single-float support on riscv64.
** optimization: support for accessing elements of &rest args directly on
ppc64, mips, riscv.
** optimization: parse a /proc file rather than executing uname for
SOFTWARE-VERSION on Linux
* bug fix: fix crash from SB-COVER:RESET-COVERAGE. (lp#1950059, reported by
Gregory Czerniak)
