Is there a D equivalent of the "xmmintrin.h", or any other convenient
way of
doing SSE in D?
- I've been looking into the Array Operators, but will those work, for
instance if I'm doing something alike:
a[3], b[4]
c[4] = a+b;
and when will the compiler write SSE asm for the array operators? - is
there
a target=architecture for the compiler? or will it simply write SSE if
one
defines something alike -msse4? - I'm having a bit of trouble finding
stuff
about SSE for D, sources on the subject anyone?
SSE is supported in inline assembly.
dmd's backend doesn't automatically vectorize code.
gdc and ldc are theoretically able to it (cause of the backends they use)
but I don't know to what extent they really do in practice.
Array operations leverage prewritten optimized SSE code if possible.
