[Gnumex-users] SSE4.2 optimization

[Sam B. <seb...@gm...>]

Hi,

Is there a way to enable sse4.2 vectorization while compiling a mex with
gcc? I tried the option -O3 -mtune=native (my machine is i7 with sse4.2
support). The code is compiled and executes but is extremely slow.
Compiling with MSVC2010 compiler I get the optimization working. I tried to
manually edit mexopts.bat to add a -sse4.2 flag but it did not work.

Thanks,
Seb
