78 | Currently, we only guarantee that I32 is *at least* 32 bits. | |
79 | Specifically, if int is 64 bits, then so is I32. (This is the case | |
80 | for the Cray.) This has the advantage of meshing nicely with | |
81 | standard library calls (where we pass an I32 and the library is | |
82 | expecting an int), but the disadvantage that an I32 is not 32 bits. | |
