...mbler to use avx instructions on Mac. I use gcc 4.7.1 to generate .s files from .c files. I can assemble foo.s by clang -c -x assembler foo.s to get foo.o but clang -c -x assembler foo_long.s fails with $clang -x assembler foo_long.s foo_long.s:27:2: error: invalid instruction mnemonic 'vcvttsd2siq' vcvttsd2siq %xmm0, %rax ^~~~~~~~~~~ clang can assemble many other .s files with avx instructions. I tried the default clang, clang+llvm 3.1 binary and svn checked out llvm/clang. All same. Have you any idea? Thank you so much! Nobu Nobu Katayama nobu.katayama at ipmu...

Hi Nobu, > Thanks for response. Will this be fixed sometime soon? did you open a bug report? > Is there anything I can do to make it work in my copy of the latest llvm source?
