@ -3251,6 +3251,18 @@ This is Sun bug 4237974. This is fixed with patch 108908-02 for Solaris
2.6 and has been fixed in later (5.x) versions of the assembler,
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.
