@ -38,6 +38,12 @@ with the pass name. For example, the affine dialect provides a loop tiling pass
that is registered on the command line as `-affine-tile`, and with a tile size
option that can be set with `-affine-tile-size`.
We also avoid `cl::opt` to provide pass options in favor of the
[pass options](WritingAPass.md#instance-specific-pass-options) mechanism. This
allows for these options to be serialized in a pass pipeline description, as
well as passing different options to multiple instances of a pass in the same
pipeline.
## Testing guidelines
