Bug#653024: clang: -march=native (sometimes?) fails

[Miles Bader]

Package: clang
Version: 3.0-5
Severity: normal

At least on this system, "-march=native" fails oddly:

   $ echo 'int main () { }' > m.cc; clang++ -o m -march=native m.cc
   error: unknown target CPU 'amdfam10'

The -march=native option _used_ to work with [the debian version of]
clang [on this same system], and seems to work with a recent clang
trunk version, so I'm not sure what's going on... something out of
sync?

[Using clang/llvm trunk:

   $ clang++-trunk -o m -march=native m.cc
   $ clang++-trunk --version
   clang version 3.1 (http://llvm.org/git/clang.git b0c6c33c3479d2cb4c3b9f5a6e58c58d07c731e7)
   Target: x86_64-unknown-linux-gnu
   Thread model: posix
]

Thanks,

-Miles
