- no more Concrete ciphertext/plaintext types: they are represented using standard MLIR types (int/tensor)
- Technically BConcrete was renamed to Concrete, and old Concrete was
removed
- TFHE -> Concrete now takes into account the conversion of tensor of
ciphertext into tensors of an additional dimension (LWE dim)
- Bufferization now works in Concrete
- Old Concrete optimization were moved to TFHE
- Concrete is now the dialect that lowers to CAPI calls
- TFHE -> Concrete now uses OpConversionPattern and is much cleaner in
terms of type conversion
- Disabled tests for batching, as there was something weird about it:
batchable operations implemented in Concrete but pass run in FHELinalg
This adds a new pass `ExtractSDGOps`, which scans a function for
operations that implement `SDFGConvertibleOpInterface`, replaces them
with SDFG processes and constructs an SDFG graph around the processes.
Initialization and teardown of the SDFG graph are embedded into the
function and take place at the beginning of the function and before
the function's terminator, respectively.
The pass can be invoked using concretecompiler by specifying the new
compilation option `--emit-sdfg-ops` or programmatically on a
`CompilerEngine` using the new compilation option `extractSDFGOps`.
