- tinfo is a part of the ncurses project.
- tinfo does not seem easily installable stand alone
(no brew install tinfo, no dnf install tinfo-devel, etc)
but installing ncurses is possible and generally makes tinfo
'findable'
- on macos (M1 mac) it seems that even with ncurses installed
tinfo is not found, but linking to ncurses fixes the problem
we want to wrap CStructs in RustStructs to own them, and free memeory
when they are no longer used. Users won't have to deal with the direct
binded CAPI, but the new wrappers
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`.
This adds a new operation interface `SDFGConvertibleOpInterface` that
allows an operation to specify how it is converted to an SDFG
process. The interface consists of a single method `convert` that
receives as the arguments the DFG created using `SDFG.init`, a set of
SDFG input streams corresponding to the operands and a set of output
streams for results. The order of the input and output streams
corresponds to the order of the operands and output values,
respectively.
This adds a new dialect called "SDFG" for data flow graphs. An SDFG
data flow graph is composed of a set of processes, connected through
data streams. Special streams allow for data to be injected into and
to be retrieved from the data flow graph.
The dialect is intended to be lowered to API calls that allow for
offloading of the graph on hardware accelerators.
C struct now contains an additonal char* pointer, which can be either
NULL in case there is no error, or a buffer containing the error
message. It's the responsability of destructor function to free that
memory.
CAPI covering a wider API of the Support library.
Better error handling. Could also be improved by returning an error
message back from C to rust (left TODO).
updated also the API to make it easier to use by:
- creating MLIR components from native rust types instead of require
MLIR components in the API
- adding helpers around the creation of standard dialects
Instead of overriding the process stderr to get
the string representation from mlir we can can
directly capture in into a string using mlir's
printOperation.
Another problem with overriding stderr is that
each `#[test]` runs as a different thread meaning that
as soon as we have 2+ tests the tests could panic
due to conflicts/races between the different overrides.
This also moves the expected string directly into the test
as a literal.
The rust bindings are intented to access both LLVM/MLIR CAPI as well as
the concrete-compiler one. This initial commit provide the API for
LLVM/MLIR only. Tests should be used as an example to how to generate a
valid DAG of operations in MLIR.
