macos - Error "no such instruction" while assembling project on Mac OS X

Question

I used homebrew to install GCC 4.7.0 and my project's make is failing at assembly-time. I can successfully take code from .c -> .s, but .s -> .o fails.

To view the brew formula used to install GCC, please look at: https://github.com/Homebrew/homebrew-dupes/blob/master/gcc.rb . I also installed binutils from upstream using https://github.com/mxcl/homebrew/blob/master/Library/Formula/binutils.rb . Install binutils does not appear to introduce a new 'as' in the /usr/local/lib or similar.

How can I track down this missing instruction error? It appears the compiler is correct but the linker simply does not support these instructions. The instructions do appear to be vector instructions.

make: *** [suricata.o] Error 1

Here is what happens when I use the GCC-4.7 installed by MacPorts (it uses cctools). I tried changing optimizations to see if that would help as well.

Adding -Wa,-q to the compiler flags fixed this problem for me. From the man pages for as:

-q

     Use the clang(1) integrated assembler instead of the GNU based system assembler.

The -Wa part passes it from the compiler driver to the assembler, much like -Wl passes arguments to the linker.
