changes in sbcl-1.1.15 relative to sbcl-1.1.14:
* 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. Thanks again to Google for their support, and, more
crucially, to Alexandra Barchunova for her hard work.
* optimization: make-array with known element-type and unknown dimensions is
much faster.
* optimization: make-array with unknown element-type is faster as well.
(lp#1004501)
* enhancement: sb-ext:save-lisp-and-die on Windows now accepts
:application-type argument, which can be :console or :gui. :gui allows
having GUI applications without an automatically appearing console window.
* 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.
* enhancement: support for "Mac Roman" external format.
* enhancement: encapsulation of named generic functions now happens without
altering the identity of the function bound to the name.
* bug fix: Windows applications without the console window no longer misbehave.
(patch by Wilfredo Velazquez, lp#1256034).
* bug fix: modular arithmetic optimizations do not stumble on dead branches
with bad constants. (reported by Douglas Katzman)
* bug fix: CLISP can be used again as a cross-compilation host.
(Thanks to Vasily Postnicov, lp#1261451)
* bug fix: run-program crashed with :directory nil. (lp#1265077)
