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.

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.
