This patch uses the new .machine directive in the Darwin assembler to

to assemble GCC's output', some of which were being worked around in
the testsuite.

This patch requires a further updated cctools to work properly.  You
can get it from
<ftp://gcc.gnu.org/pub/gcc/infrastructure/cctools-528.5.tar.bz2> in
source form, and an installable package at
<ftp://gcc.gnu.org/pub/gcc/infrastructure/cctools-528.5.dmg>.

Ideally this would all be conditional on cctools version, but
failing that, it would be helpful to mention this dependency in
the building-from-source docs.


It can't be conditional on cctools version without having specs conditional on that version, which seemed like a lot of work for no point (since you already have to upgrade to -528, going -528.5 doesn't seem like it would be any extra burden).

You can build GCC, I think, with the previous cctools. You just can't use -mcpu= with a non-default setting and no other flags.

Clunk (and not even a bootstrap).

So yes, need to update doc/install.texi at least.
