## Installation
[RFC] Doc-check utility. (#12) * 1. Implement doc-check utility. * 1. Move ONNF installation script to a standalone script file. * 1. Modify build script to install llvm-project next to ONNF. The build script used to install llvm-project inside ONNF, which didn't make sense. * 1. Check out code to ONNF directory. * 1. Pass path parameter correctly. * 1. Debugging buildbot. * 1. Remove debug code. * 1. Update installation instructions in README.md. 2. Enforce consistency with scripts used in testing using doc-check. * 1. Fix error with respect to syntax to build multiple CMake targets. * 1. Move doc-check to doc_check. 2. Remove directive_config in top-level driver. * 1. Build onnf and check-mlir-lit separately because only CMake 3.15+ supports building multiple targets in one cmake --build run. * 1. Use new env variables to locate LLVM-Project. * 1. Documentation nits. * 1. Prettify buildbot scripts. * 1. Fix build script error. * 1. Support exclude_dirs in DocCheck. 2. Add README for DocCheck. * 1. Mark python3 interpreter as required. 2. Use imported interpreter target. * 1. Automatically deduce doc file extension in DocCheckCtx. 2. Rename ctx.open -> ctx.open_doc since it should only be used to open doc file. 3. Always read line in parser, instead of reading lines in driver and then passing it to parser.py. * 1. Rename parser -> doc_parser due to name conflict with python built-in module. 2. Explose doc_check module directory first before importing; otherwise if the doc_check utility is invoked by other script, importing will not work correctly. * 1. Keep renaming parser -> doc_parser. 2. Explicitly define a default configuration parser that parses the configuration into a python dictionary. * 1. Add test for doc-check. 2. Exclude doc-check tests from project dock-check because base directory is different. * 1. Raise ValueError if directive configuration fails to parse. 2. Format code. * Shorten test case documentation. Show example of using same-as-file directive, check with DocCheck. * 1. Shorten test case documentation. 2. More documentation, check documentation with DocCheck. * 1. Add copyright notice. * 1. Make documentation clearer. 2. Prettify build-scripts. * 1. Provide more documentation. 2. Fix some non-compliance with pep8 recommendations. Co-authored-by: Gheorghe-Teodor Bercea <gt.bercea@gmail.com>

Firstly, install MLIR (as a part of LLVM-Project):
[same-as-file]: <> (utils/install-mlir.sh)
``` bash
git clone https://github.com/llvm/llvm-project.git
mkdir llvm-project/build
cd llvm-project/build
cmake -G Ninja ../llvm \
-DLLVM_ENABLE_PROJECTS=mlir \
-DLLVM_BUILD_EXAMPLES=ON \
-DLLVM_TARGETS_TO_BUILD="host" \
-DCMAKE_BUILD_TYPE=Release \
-DLLVM_ENABLE_ASSERTIONS=ON \
-DLLVM_ENABLE_RTTI=ON
cmake --build . --target check-mlir -- ${MAKEFLAGS}
```

Two environment variables need to be set:
Update README.md (#23)
2020-01-14 00:40:51 +08:00
- LLVM_PROJ_SRC should point to the llvm-project src directory (e.g., llvm-project/).
- LLVM_PROJ_BUILD should point to the llvm-project build directory (e.g., llvm-project/build).

After the above commands succeed, an `onnf` executable should appear in the `bin` directory.
## Using ONNF
The usage of `onnf` is as such:
```
OVERVIEW: ONNF MLIR modular optimizer driver
USAGE: onnf [options] <input file>
OPTIONS:
Generic Options:
--help - Display available options (--help-hidden for more)
--help-list - Display list of available options (--help-list-hidden for more)
--version - Display the version of this program
ONNF Options:
These are frontend options.
Choose target to emit:
--EmitONNXIR - Ingest ONNX and emit corresponding ONNX dialect.
--EmitMLIR - Lower model to MLIR built-in transformation dialect.
--EmitLLVMIR - Lower model to LLVM IR (LLVM dialect).
--EmitLLVMBC - Lower model to LLVM IR and emit (to file) LLVM bitcode for model.
```
## Example
For example, to lower an ONNX model (e.g., add.onnx) to ONNX dialect, use the following command:
```
./onnf --EmitONNXIR add.onnx
```
The output should look like:
```
module {
func @main_graph(%arg0: tensor<10x10x10xf32>, %arg1: tensor<10x10x10xf32>) -> tensor<10x10x10xf32> {
%0 = "onnx.Add"(%arg0, %arg1) : (tensor<10x10x10xf32>, tensor<10x10x10xf32>) -> tensor<10x10x10xf32>
return %0 : tensor<10x10x10xf32>
}
}
```
