starting with Solaris 7.

|

|
Starting with Solaris 7, the operating system is capable of executing
|
||||||
|
64-bit SPARC V9 binaries. GCC 3.0 doesn't properly support this yet.
|
||||||
|
Although some patches or recipes to enable this support have been posted
|
||||||
|
to various newsgroups and mailing lists, we recommend against using
|
||||||
|
them, since the compiler may either crash or, worse, silently generate
|
||||||
|
bad code. If you really need this capability now, you might try a CVS
|
||||||
|
version of GCC 3.1, which will fully support this. If all you want is
|
||||||
|
code tuned for the UltraSPARC CPU, you should try the
|
||||||
|
@option{-mtune=ultrasparc} option instead, which should be safe from
|
||||||
|
those bugs and produce code that, unlike full 64-bit code, can still run
|
||||||
|
on non-UltraSPARC machines.
