0:19:50stassatsand i'm doing manual ir1 manipulation without using transforms, after all ir1 optimizations are done, to not lose VECTOR-LENGTH being folded
0:20:33stassatsi guess i can come up with some easier pattern matching, since it should only need to change the combination fun, delete the unnecessary one, rearrange the args
0:20:56stassatsand then apply to something more interesting than vector-length+check-bound
0:28:45stassatsor even easier (no new vops) make (lambda (a) (declare (notinline %ldb)) (ldb (byte 32 63) a)) as fast without notinline, by folding it back to %ldb
0:30:45stassatsactually here a modular out-of-line ASH could help
