IMHO, which is shared by the GCC documentation, the Sun assembler should
be used, so unless AS is set, it would be wise to use /usr/ccs/bin/as. (On
Solaris 11 and !OpenSolaris, there's a link to /usr/bin/as, but that's not
true on Solaris 10).
http://gcc.gnu.org/install/specific.html#ix86-x-solaris210
says on the Solaris x86 notes.
----
''It is recommended that you configure GCC to use the GNU assembler, in
/usr/sfw/bin/gas. The versions included in Solaris 10, from GNU binutils
2.15, and Solaris 11, from GNU binutils 2.19, work fine, although the
current version, from GNU binutils 2.21, is known to work, too. Recent
versions of the Sun assembler in /usr/ccs/bin/as work almost as well,
though.''
''For linking, the Sun linker, is preferred.''
It also says ''It may be necessary to configure with --without-gnu-ld
--with-ld=/usr/ccs/bin/ld to guarantee use of Sun ld.''
------------
I thought the configure script would work out the --without-gnu-ld, but it
might be worth adding the option unless LD is set.
I don't know what the status of t2.math is. William said he was going to
switch it on a couple of weeks ago, but last time I looked it was down.
Also, not sure about SkyNet.
If we need a Solaris 11 x86 machine I have one. A bit limited in
performance (pair of dual core 2.8 GHz Opterons and 8 GB RAM, but it is
useable. It's running the latest release of Solaris 11. I really need to
work out how to use the remote management on it, as it is very noisy, must
be placed in the garage, but I don't know how to manage it properly on
it's management port.
