| 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. |
| 83 | Andy Dougherty August 1996 |
| 84 | |
| 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. |
| 88 | |
| 89 | Similarly, there is no guarantee that I16 and U16 have exactly 16 |
| 90 | bits. |
| 91 | |
| 92 | For dealing with issues that may arise from various 32/64-bit |
| 93 | systems, we will ask Configure to check out |
| 94 | |
| 95 | SHORTSIZE == sizeof(short) |
| 96 | INTSIZE == sizeof(int) |
| 97 | LONGSIZE == sizeof(long) |
| 98 | LONGLONGSIZE == sizeof(long long) (if HAS_LONG_LONG) |
| 99 | PTRSIZE == sizeof(void *) |
| 100 | DOUBLESIZE == sizeof(double) |
| 101 | LONG_DOUBLESIZE == sizeof(long double) (if HAS_LONG_DOUBLE). |

| 390 | XXX LEAKTEST doesn't really work in perl5. There are direct calls to |
| 391 | safemalloc() in the source, so LEAKTEST won't pick them up. |
| 392 | Further, if you try LEAKTEST, you'll also end up calling |
| 393 | Safefree, which might call safexfree() on some things that weren't |
| 394 | malloced with safexmalloc. The correct "fix" to this, if anyone |
| 395 | is interested, is to ensure that all calls go through the New and |
| 396 | Renew macros. |
