this required to have a CAPI that when asked for types, returns a
structure that can report if an error was faced during type creation.
This is required since a failure at that stage in the compiler would
lead to a segfault in the python bindings for example, and we want to be
able to handle this scenario gracefully.
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.
Bench just one compilation option for automatic benchmarks. Only 'loop'
option is tested to take advantage of hardware with a lot of available
CPUs. Running benchmarks with 'default' option is suboptimal for this
kind of hardware since it uses only one CPU.
This also remove time consuming MNIST test, as it should be in ML benchmarks.
Moreover Makefile is fixed to use provided Python executable instead of
relying on system one to generate MLIR Yaml files.
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.
converting types of the original op seems to have an impact on other
operations using the result type, which should consider checking the
different cases (whether the type has been converted yet, or not).
However, creating a new op don't have this issue
- unify CPU and GPU bootstrapping operations
- remove operations to build GLWE from table: this is now done in
wrapper functions
- remove GPU memory management operations: done in wrappers now, but we
will have to think about how to deal with it later in MLIR
This includes several fixes and add some functionalities:
* EC2 instance type can be selected when workflow is triggered manually
* benchmarks will be run on each push on main branch
* docker is not used any more due to building issues
* 10 repetitions are made during the benchmarks then results are aggregated
* more tags are used to identify benchmarks configuration
This updates the llvm-project repository to a version containing a
patch that avoids excessive stack growth for programs whose IR
contains `memref.copy` operations in the bodies of loops with a high
trip count (e.g., `mnist_28_mlir_7b`).
This fixes Issue #669.
When building the ServerLib before any other concretelang target that
depends on `mlir-headers`, compilation fails due to missing include
files generated by tablegen, e.g., `llvm/IR/Attributes.inc`.
This adds a dependency from ServerLib to `mlir-headers`, which forces
the generation of the missing header files.
This adds four new targets `opt`, `mlir-cpu-runner`, `mlir-opt`, and
`mlir-translate` to the toplevel Makefile of the compiler to
conveniently build the corresponding LLVM / MLIR utilities (e.g., for
debugging purposes).
