Re: llvm 3.1

[Brian Callahan]

I believe that it defaults to N64 if it detects a mips64* arch, O32 
otherwise.
I'll test the patch and report back.

Sorry, I forgot to add a few more caveats to the mips64el build:

You need the patch at the bottom of this email (hopefully
Thunderbird won't mangle it).

Additionally, I ported gas-2.22 to the loongson, which is needed for
the loongson build. I can send that separately, if such a port is
desired.

Thanks.

~Brian

you'll need to modify the driver as well

Here is a diff against clang svn that adds OpenBSD specific
arm/mips64/mips64el/powerpc/sparc targets.  If the gcc config has
arch specific OpenBSD settings that differ from the defaults
more will have to be done.

I don't know if this is enough as I've only compile tested
it on i386.  In particular I'm not sure which arm/mips64 abi
is being defaulted to.
