Is there such a thing as a "true 64bit perl" where the number of elements in an array would be indexed with, say, a 64bit int data type?
I've been told there exists compilers on some 64-bit systems where sizeof(int) == 8. One would expect that a perl built with such a compiler would index its arrays with a 64-bit integer data type.
I don't have access to any "-Duse64bitall" builds of perl. I assumed they would index their arrays with a 64-bit integer data type, but am unable to check.
Note also that the *absence* of the use64bitxxx flags does not imply 32-bits. (You need to examine other flags, such as ivsize.) From the INSTALL file that ships with the perl source:
################################# Natively 64-bit systems need neither -Duse64bitint nor -Duse64bitall. On these systems, it might be the default compilation mode, and there is currently no guarantee that passing no use64bitall option to the Configure process will build a 32bit perl. Implementing -Duse32bit* options is planned for a future release of perl. ################################# Cheers, Rob _______________________________________________ Perldl mailing list [email protected] http://mailman.jach.hawaii.edu/mailman/listinfo/perldl
