[Backend] Support GetBitOp/SetBitOp in LLVM #35

Closed chhzh123 closed 2 years ago

chhzh123 commented 2 years ago

hcl.get_bit/hcl.set_bit operation has been supported by VHLS backend, but it is still not supported by LLVM. It should be relatively straightforward to perform get/set_bit by shifting and ANDing.

Also need to support get/set_slice and reverse operations in LLVM.
