Here's a test from HLSL:

RWStructuredBuffer<float> buffer2 : register(u1);

Still needs testing:
mul()
atomic functions
transpose()
refract(), reflect()
normalize()
lit()
length()
faceforward()
dot(), cross(), distance(), dst()
determinant()
Also: it looks like HLSL doesn't have fma(), isnormal(), isordered(), and isunordered(). count_bits() needs to be renamed to countbits(), and asfloat() needs to exist.
