- ASDFが3.0.2にアップデートされました。
- x86系でスタックフレームがより効率的に格納されるようになりました optimization: stack frames are packed more efficiently on x86oids, which ought to reduce the frequency of Methuselahn conservative references (it certainly helps with gc.impure.lisp / BUG-936304 on x86).
- x86とx86-64で、整数の optimization: on x86 and x86-64, integer negation forms like (- x) are now recognized in modular arithmetic contexts, and compile to native negate, rather than going through bignums only to keep the low bits.
