link errors; e.g. __builtin_ia32_cvtdq2ps using icc 12.1.3.20120212 under 64-bit linux

[Jim_Veitch]

Hi, I see link errors building gcc code:

undefined reference to `__builtin_ia32_loadups'

undefined reference to `__builtin_ia32_punpcklwd128'

etc.

This is code to vectorize under gcc, which is our major development environment.

Any ideas what I can do? Is there some sort of compatibility lag I should be using?

Here is the link command:

OK I have resolved this. GCC intrinsics are different than ICC intrinsics, but it turns out that GCC also has header files maps ICC to GCC intrinsics. Reading this header file tells me how to map GCC to ICC instead.
