I use some numerical code utilizing the SIMD units of modern X86 architectures. Code compiles well using gcc/gcc46, but clang does not know about the __builtin_ia32_xxxxx() statements. How to treat those in clang and how to make C code compiling with clang utilizing those __builtin_ia32 statements? Thanks, Oliver
