This refactoring commit restructures the compilation pipeline of
`zamacompiler`, such that it is possible to enter and exit the
pipeline at different points, effectively defining the level of
abstraction at the input and the required level of abstraction for the
output.
The entry point is specified using the `--entry-dialect`
argument. Valid choices are:
`--entry-dialect=hlfhe`: Source contains HLFHE operations
`--entry-dialect=midlfhe`: Source contains MidLFHE operations
`--entry-dialect=lowlfhe`: Source contains LowLFHE operations
`--entry-dialect=std`: Source does not contain any FHE Operations
`--entry-dialect=llvm`: Source is in LLVM dialect
The exit point is defined by an action, specified using --action.
`--action=roundtrip`:
Parse the source file to in-memory representation and immediately
dump as text without any processing
`--action=dump-midlfhe`:
Lower source to MidLFHE and dump result as text
`--action=dump-lowlfhe`:
Lower source to LowLFHE and dump result as text
`--action=dump-std`:
Lower source to only standard MLIR dialects (i.e., all FHE
operations have already been lowered)
`--action=dump-llvm-dialect`:
Lower source to MLIR's LLVM dialect (i.e., the LLVM dialect, not
LLVM IR)
`--action=dump-llvm-ir`:
Lower source to plain LLVM IR (i.e., not the LLVM dialect, but
actual LLVM IR)
`--action=dump-optimized-llvm-ir`:
Lower source to plain LLVM IR (i.e., not the LLVM dialect, but
actual LLVM IR), pass the result through the LLVM optimizer and
print the result.
`--action=dump-jit-invoke`:
Execute the full lowering pipeline to optimized LLVM IR, JIT
compile the result, invoke the function specified in
`--jit-funcname` with the parameters from `--jit-args` and print
the functions return value.
The function `getV0Parameter()` returns a pointer to a static array,
which is not intended to be mutable. Reflect this in the return type
of the function.
Replace the macros `LOG_VERBOSE` and `LOG_ERROR` with C++-style
streams retrieved through `log_verbose()` and `log_error()`. This
aligns with the `MLIR` infrastructure and avoids pollution of the
global namespace through a common header file in subsequent
refactoring commits splitting the functionality of `src/main.cpp` into
multiple files.
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
We currently use LD_PRELOAD with the python extension to make the JIT
execution find the appropriate symbols, however, not linking with some
libraries caused other tools such as make to complain of not finding
symbols from libpthread and others
The polynomialSize is currently holding its log2 instead of the actual
value. This should be fixed later, but in the meantime, we need to
compute it from log2
