output size of keyswiting wasn't set properly. As this information must
come from the selected parameters, it should goes down from the MidLFHE
to the appropriate call to ciphertext allocation
This changes the semantics of `HLFHE.dot_eint_int` from memref-based
reference semantics to tensor-based value semantics. The former:
"HLFHE.dot_eint_int"(%arg0, %arg1, %arg2) :
(memref<Nx!HLFHE.eint<0>>, memref<Nxi32>, memref<!HLFHE.eint<0>>) -> ()
becomes:
"HLFHE.dot_eint_int"(%arg0, %arg1) :
(tensor<Nx!HLFHE.eint<0>>, tensor<Nxi32>) -> !HLFHE.eint<0>
As a side effect, data-flow analyses become much easier. With the
previous memref type of the plaintext argument it is difficult to
check whether the plaintext values are statically defined constants or
originate from a memory region changed at execution time (e.g., for
analyses evaluating the impact on noise). Changing the plaintext type
from `memref` to `vector` makes such analyses significantly easier.
-Encoding Cleartext to Plaintext Op
-Encoding Int to Plaintext Op
-Cleartext/Plaintext should add a bits field as `p`
-Op to create a constant Cleartext
-IntToCleartextOp: kind of casting an int to be later encoded, I'm not
sure if there is a better mechanism for this (e.g. auto casting in Ops),
but we currently need a way to encode int into plaintext, and we need to
go through cleartexts

This adds a new command line option
`--convert-hlfhe-tensor-ops-to-linalg` that invokes a conversion pass
replacing any HLFHE tensor operation with an appropriate instance of
`linalg.generic`.
Add a simple dot product between a vector of encrypted integers and a
vector of plaintext integers to the HLFHE dialect.
The operation takes two input operands and one output operand, all
modeled as memrefs. Example:
"HLFHE.dot_eint_int"(%lhs, %rhs, %out) :
(memref<?x!HLFHE.eint<0>>, memref<?xi32>, memref<!HLFHE.eint<0>>) -> ()
Make `HLFHE.EncryptedInteger` implement the
`MemRefElementTypeInterface` trait to allow the type to be used for
elements of memrefs.
The invocation of the `add_mlir_dialect` macro in
`include/zamalang/Dialect/HLFHE/IR/CMakeLists.txt` had to be broken
into its parts in order to pass `-typedefs-dialect=HLFHE` to
`mlir-tablegen`. This is required due to the inclusion of
`mlir/IR/BuiltinTypes.td` in
`include/zamalang/Dialect/HLFHE/IR/HLFHETypes.td`, resulting in
definitions from multiple dialects.
Add a small test actually using `HLFE.EncryptedInteger` in a `memref`.
