134/* XXX A note on the perl source internal type system. The
135 original intent was that I32 be *exactly* 32 bits.
136
137 Currently, we only guarantee that I32 is *at least* 32 bits.
138 Specifically, if int is 64 bits, then so is I32. (This is the case
139 for the Cray.) This has the advantage of meshing nicely with
140 standard library calls (where we pass an I32 and the library is
141 expecting an int), but the disadvantage that an I32 is not 32 bits.

144 There is no guarantee that there is *any* integral type with
145 exactly 32 bits. It is perfectly legal for a system to have
146 sizeof(short) == sizeof(int) == sizeof(long) == 8.
693762b4 147

148 Similarly, there is no guarantee that I16 and U16 have exactly 16
149 bits.

731In 5.9.3, Newx() and friends replace the older New() API, and drops
732the first parameter, I<x>, a debug aid which allowed callers to identify
37b8b4c9 733themselves. This aid has been superseded by a new build option,

734PERL_MEM_LOG (see L<perlhack/PERL_MEM_LOG>). The older API is still
735there for use in XS modules supporting older perls.
