## AIE Auto Vectorize Tool

VSI has an auto vectorizer to help optimize user code for running on the AIE processors.

### Installing AIE Auto Vectorize Tool

1. Download the AIE auto vectorize tool from [Here](https://systemview.s3.amazonaws.com/vsi_llvm.tgz)

2. Untar the vsi_llvm.tgz  
`tar -xvf vsi_llvm.tgz`

3. Open clang_cmd.sh, in the following path:  
`<VSI_LLVM Install Path>/llvm-project/vsi-aiebe/test/vectorize_tests/`  
and modify all the llvm-exec path to  
`<VSI_LLVM Install Path>/llvm-exec`  

### Running the Auto Vectorizer

1. To run the auto vectorizer execute the following command:  
`./clang_cmd.sh -Os <<file>> <<func>>`  
where  
	- `-Os` is the compiler flag for size optimization
	- `<<file>>` is the name of the c++ file without extension
	- `<<func>>` is the name of top level function in the c++ code
2. AIE auto Vectorize tool will generate the vectorized code with ".cpp" extension.
