- Update to version 1.1.15
* New feature:
the iterative spilling/coloring register allocator developed
by Alexandra Barchunova during Google Summer of Code 2013 is
now merged in. By default, it only activates for functions that
optimize with (speed 3) and (> speed compilation-speed), but
setting sb-regalloc:*register-allocation-method* to :iterative
forces its execution. The previous behaviour can be obtained by
instead setting that variable to :greedy.
* Optimization:
+ make-array with known element-type and unknown dimensions is
much faster.
+ make-array with unknown element-type is faster as well.
(lp#1004501)
* Enhancement:
+ reduced conservativism on GENCGC platforms: conservative roots
must be valid-looking tagged pointers or point within a code
object, not merely point to within the allocated part of a
page, in order to pin a page.
+ support for "Mac Roman" external format.
+ encapsulation of named generic functions now happens without
altering the identity of the function bound to the name.
* Bug fix:
+ modular arithmetic optimizations do not stumble on dead branches
with bad constants. (reported by Douglas Katzman)
+ CLISP can be used again as a cross-compilation host.
