Hi,
I'm trying to compile our C++ code that makes use of SSE 4.1 intrinsics.
I'm on OSX 10.11.6 using emscripten-incoming-64bit on commit
a28973d1b60a22723768e4e2bbe77b6795f964d1
The emscripten command I'm running is:
path/to/emscripten/incoming/em++ --pre-js
/Users/joe/Desktop/test2/js/hv_wrapper.js
/Users/joe/Desktop/test2/c/Heavy_heavy.cpp

And the errors I get are these:

It looks like it can't find the builtin x86 functions, I'm not that
familiar with the emscripten build system so I'm wondering if there's
something I'm misssing?
Note: i had to change the #include <immintrin.h> declaration we usually
have to #include <smmintrin.h> for emscripten to find the SSE4.1 intrinsics.
Any pointers would be much appreciated!
Thanks,
Joe
