27d4fb96 | 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 | |

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 MB |
89 | Similarly, there is no guarantee that I16 and U16 have exactly 16 |
90 | bits. | |
693762b4 | 91 | |
dc45a647 MB |
92 | For dealing with issues that may arise from various 32/64-bit |
93 | systems, we will ask Configure to check out | |
94 | SHORTSIZE == sizeof(short) | |
95 | INTSIZE == sizeof(int) | |
96 | LONGSIZE == sizeof(long) | |
97 | LONGLONGSIZE == sizeof(long long) (if HAS_LONG_LONG) | |
98 | PTRSIZE == sizeof(void *) | |
99 | DOUBLESIZE == sizeof(double) | |
100 | LONG_DOUBLESIZE == sizeof(long double) (if HAS_LONG_DOUBLE). | |
101 | Most of these are currently unused, but they are mentioned here so | |
102 | metaconfig will include the appropriate tests in Configure and | |
103 | we can then start to consider how best to deal with long long | |
104 | variables. | |

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