Before building, the command gensimd and the package github.com/bjwbell/gensimd/simd need to be installed. To do so, execute:
go get github.com/bjwbell/gensimd
go install github.com/bjwbell/gensimd
go get github.com/bjwbell/gensimd/simd
After that, to build and run the example, execute:
go generate
go build
./simd_example
This example only uses SIMD instructions on amd64/x86_64, on any other platforms it uses Go versions of the SIMD functions.
