75 | /* XXX A note on the perl source internal type system. The |
76 | original intent was that I32 be *exactly* 32 bits. |
77 | |
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. |

85 | There is no guarantee that there is *any* integral type with |
86 | exactly 32 bits. It is perfectly legal for a system to have |
87 | sizeof(short) == sizeof(int) == sizeof(long) == 8. |
693762b4 |
88 | |
dc45a647 |
89 | Similarly, there is no guarantee that I16 and U16 have exactly 16 |
90 | bits. |
693762b4 |
91 | |

92 | For dealing with issues that may arise from various 32/64-bit |
93 | systems, we will ask Configure to check out |

380 | /* This looks obsolete (IZ): |
381 | |
382 | XXX LEAKTEST doesn't really work in perl5. There are direct calls to |
27d4fb96 |
383 | safemalloc() in the source, so LEAKTEST won't pick them up. |
384 | Further, if you try LEAKTEST, you'll also end up calling |
385 | Safefree, which might call safexfree() on some things that weren't |
386 | malloced with safexmalloc. The correct "fix" to this, if anyone |
387 | is interested, is to ensure that all calls go through the New and |
388 | Renew macros. |
