32 Bigstring intrinsics and fast blits based on memcpy/memmove
33
34 The OCaml compiler has a bunch of intrinsics for Bigstrings, but they're not
35 widely-known, sometimes misused, and so programs that use Bigstrings are slower
36 than they have to be. And even if a library got that part right and exposed the
37 intrinsics properly, the compiler doesn't have any fast blits between
38 Bigstrings and other string-like types.
39
40 So here they are. Go crazy.
