The arm_neon.h header does not give correct results:

For instance this code:

 out = vshll_n_u8(qTmp_u8,8);

gives the error:

"C2338: invalid shift ammount"

Which is both linguistically and technically wrong, as the ARM documentation ( states that:

VSHLL{cond}.datatype Qd, Dm, #imm 
is the immediate value specifying the size of the shift, in the range:
1 to size(datatype) for VSHLL
