changes in sbcl-2.4.7 relative to sbcl-2.4.6:
* minor incompatible change: the compiler will emit optimization notes
related to complex type checks only at high SPEED optimization settings.
* minor incompatible change: the GET-FOREGROUND symbol is now exported from
the SB-THREAD package. (thanks to Philipp Marek)
* minor incompatible change: code objects are now printed with their ending
address as well as their start address.
* platform support:
** fix occasional saved core corruption on Win32. (reported by Luís
Borges de Oliveira)
** address some crashing cases in arena support. (reported by Andreas
Franke)
** fix a hard-coded path to `cp`. (thanks to Hraban Luyat)
** address relocation issues on PIC-flavoured arm64. (lp#2067153, thanks
to leafze)
** fix a crash in the arm64-dissassembler if a code component is missing.
** fix a crash on 32-bit musl libc systems. (reported by Will Sinatra)
** fix building with link-time optimization. (lp#2072800, reported by Eli
Schwartz)
** fix building with newer llvm. (lp#2071545, reported by Yan)
** mitigate the lack of gc-safety in SB-VM::REMOVE-STATIC-LINKS.
(lp#2045433)
* bug fix: COMPILE installs its second argument as the value of its non-null
NAME argument, even if the second argument was already compiled.
(lp#2071324, reported by Tim Bradshaw)
* bug fix: allow the hashing routines in sb-md5 to work on arrays with more
than 2^29 elements.
* bug fix: allow READ-SEQUENCE and WRITE-SEQUENCE to read and write files
bigger than 4GB.
* bug fix: READ-SEQUENCE returns the index of the first unmodified element
of its sequence. (reported by Janis Dzerins)
* optimization: various improvements to floating point rounding routines.
* optimization: PHASE called on the result of COMPLEX now elides the
intermediate COMPLEX object.
* optimization: the compiler is more aware of the types of COMPLEX, ATAN,
APPEND and NCONC.
