Bitwise shift of buffer in CUDA

Is there any way to memmove a buffer in CUDA in a bitwise manner? Eg, for a buffer with two bytes and a pointer

buf -> 00000000 11111111

I would like to shift bit portions left or right given their bit offset. Something like

void memmove(void* buf, int from, int bits, int delta)

For the buffer above I would expect then:

00000111 11111111

after calling

memmove(buf,8,3,-3)

I could not find a proper function for this in CUDA's documentation or Google.

Please notice: I am not interested in cudaMemcpy or the normal memmove . A bitwise memmove is what I need!
I am also aware on how to do this with normal CPU, I need a more efficient alternative and therefore I am considering CUDA.
