Perl 5 compiled out of the box.
+7.0) 64-bitness, from Alan Burlison (added by jhi 2000-02-21)
+
+ You need a machine running Solaris 2.7 or above.
+
+ Here's some rules:
+
+ 1. Solaris 2.7 and above will run in either 32 bit or 64 bit mode,
+ via a reboot.
+ 2. You can build 64 bit apps whilst running 32 bit mode and vice-versa.
+ 3. 32 bit apps will run under Solaris running in either 32 or 64 bit mode.
+ 4. 64 bit apps require Solaris to be running 64 bit mode
+ 5. It is possible to select the appropriate 32 or 64 bit version of an
+ app at run-time using isaexec(3).
+ 6. You can detect the OS mode using "isainfo -v", e.g.
+ fubar$ isainfo -v # Ultra 30 in 64 bit mode
+ 64-bit sparcv9 applications
+ 32-bit sparc applications
+ 7. To compile 64 bit you need to use the flag "-xarch=v9".
+ getconf(1) will tell you this, e.g.
+ fubar$ getconf -a | grep v9
+ XBS5_LP64_OFF64_CFLAGS: -xarch=v9
+ XBS5_LP64_OFF64_LDFLAGS: -xarch=v9
+ XBS5_LP64_OFF64_LINTFLAGS: -xarch=v9
+ XBS5_LPBIG_OFFBIG_CFLAGS: -xarch=v9
+ XBS5_LPBIG_OFFBIG_LDFLAGS: -xarch=v9
+ XBS5_LPBIG_OFFBIG_LINTFLAGS: -xarch=v9
+ _XBS5_LP64_OFF64_CFLAGS: -xarch=v9
+ _XBS5_LP64_OFF64_LDFLAGS: -xarch=v9
+ _XBS5_LP64_OFF64_LINTFLAGS: -xarch=v9
+ _XBS5_LPBIG_OFFBIG_CFLAGS: -xarch=v9
+ _XBS5_LPBIG_OFFBIG_LDFLAGS: -xarch=v9
+ _XBS5_LPBIG_OFFBIG_LINTFLAGS: -xarch=v9
+
+ > > Now, what should we do, then? Should -Duse64bits in a v9 box cause
+ > > Perl to compiled in v9 mode? Or should we for compatibility stick
+ > > with 32 bit builds and let the people in the know to add the -xarch=v9
+ > > to ccflags (and ldflags?)?
+
+ > I think the second (explicit) mechanism should be the default. Unless
+ > you want to allocate more than ~ 4Gb of memory inside Perl, you don't
+ > need Perl to be a 64-bit app. Put it this way, on a machine running
+ > Solaris 8, there are 463 executables under /usr/bin, but only 15 of
+ > those require 64 bit versions - mainly because they invade the kernel
+ > address space, e.g. adb, kgmon etc. Certainly we don't recommend users
+ > to build 64 bit apps unless they need the address space.
