Back to top- build changes
- Cross-compilation host is now specified to make.sh using
command-line argument --xc-host=<command> instead of a positional
argument. (thanks to Daniel Herring)
- Install location can be specified to make.sh using command-line
argument --prefix=<path>. (#550889s, thanks to Daniel Herring)
- optimization: The default implementation of
COMPUTE-DISCRIMINATING-FUNCTION does much less wasted work.
- enhancement: Explicit memory barrier operations are now available for use
by multithreaded code. See documentation for details.
- enhancement: Experimental support for threading on Linux/PPC.
- bug fix: RENAME-PACKAGE returns the package. (Thanks to Eric Marsden)
- bug fix: EXPT signals an error if first argument is a zero and second
argument is a floating point zero. (#571581, thanks to Roman Marynchak)

(#612998, reported by Phil Hargett; patch from Jim Wise)
New in version 1.0.41
Back to top- optimization: validity of observed keyword initargs to MAKE-INSTANCE is
cached, leading to many fewer expensive calls to
COMPUTE-APPLICABLE-METHODS.
- optimization: in the (unoptimized) general method for MAKE-INSTANCE on a
CLASS argument, search for and call an appropriate optimized ctor function
if it exists.
- bug fix: WRITE always returns the correct value.
