75 /* XXX A note on the perl source internal type system. The
76 original intent was that I32 be *exactly* 32 bits.
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 In the future, we may perhaps want to think about something like
100 except that still won't work if a system has no integral type
101 with a size that is 32 bytes.
103 Further, we need to know about PTRSIZE == sizeof(void *) and
104 DOUBLESIZE == sizeof(double) if we really want to try to handle
105 32/64-bit combinations. Finally, we might also need to know
106 HAS_LONG_DOUBLE and LONG_DOUBLESIZE.
108 For the moment, these are only mentioned here so metaconfig will
109 construct Configure to figure out the various sizes.
