Microsoft Specific

Emits the merge register form of the IPF Deposit (dep) instruction, which is used for copying a number of bits specified by len from a value source into a value value in a register at the bit position specified by pos.


__m64 __m64_dep_mr( 
   __m64 source, 
   __m64 value, 
   const int pos, 
   const int len 
);

[in] source

The value from which to extract the bits for the merge.

[in] value

The value into which to merge.

[in] pos

The destination bit position for the merge into value. Valid values from 0 to 63.

[in] len

The number of bits to merge. Valid values from 1 to 16.
