Hi Tim.

Thanks for the response. I tried the x86 suggestion but it didn't work.
Clearly I'm doing something wrong, but I don't know what exactly. I would
really appreciate your help in this. Here is the command line I'm using

clang -S test.c -o test.sse2.x86_64.s --target=x86_64-pc-linux-gnu
-mfloat-abi=hard -mcpu=k8 -mfpu=SSE2 -fslp-vectorize-aggressive
-fslp-vectorize-aggressive -fslp-vectorize -fvectorize
-fno-lax-vector-conversions -O3

Here is the response that I get:

clang-3.5: warning: argument unused during compilation: '-mfloat-abi=hard'
clang-3.5: warning: argument unused during compilation: '-mcpu=k8'
clang-3.5: warning: argument unused during compilation: '-mfpu=SSE2'
error: unable to create target: 'No available targets are compatible with
this triple, see -version for the available targets.'

clang --version command produces the following result:

clang version 3.5.0
Target: x86_64-unknown-linux-gnu
Thread model: posix

test.c is attached to this email.

So what am I doing wrong?
