20 ;; (1) This is not FLUSHABLE because it's defined to signal errors.
21 ;; (2) It's not worth trying to make this FOLDABLE in the
22 ;; cross-compiler,because
23 ;; (a) it would probably be really hard to make all the
24 ;; tricky issues (e.g. which specialized array types are
25 ;; supported) match between cross-compiler and target
26 ;; compiler, and besides
27 ;; (b) leaving it not FOLDABLE lets us use the idiom
28 ;; (COERCE FOO 'SOME-SPECIALIZED-ARRAY-TYPE-OR-ANOTHER)
29 ;; as a way of delaying the generation of specialized
30 ;; array types until runtime, which helps us keep the
31 ;; cross-compiler's dumper relatively simple and which
32 ;; lets us preserve distinctions which might not even exist
33 ;; on the cross-compilation host (because ANSI doesn't
34 ;; guarantee that specialized array types exist there).
35 ;; FIXME: It's actually not clear that COERCE on non-NUMBER types
36 ;; is FOLDABLE at all. Check this.
