Compile & boost Panda with SSE instructions in Windows

Hi, just to give you a small trick on how to get Panda build use SSE2 instructions

Go and modify makepanda.py at roughly line 755 and add the following compiler options (intrinsic + SSE2)

        if (optlevel==3): cmd += " /MD /Zi /O2 /Ob2 /Oi /Ot /arch:SSE2 /DFORCE_INLINING"
        if (optlevel==4): cmd += " /MD /Zi /Ox /Ob2 /Oi /Ot /arch:SSE2 /DFORCE_INLINING /DNDEBUG /GL"

That’s it!

BTW. I’m still working on a way to get :
[b]> loop vectorization of code

block vectorization
and SSE up to SSE4[/b]

Will keep you posted on progress !
