| * Remove the unused CellInfo::pins fieldgatecat2021-02-104-37/+0
|/ | | | | | | | | | | No arches ever actually used this to implement a Cell->Bel pin mapping, and in practice if any did try they would inevitably hit bitrot. This field had limited use in practice as it is necessary to also support cases where one cell pin maps to more than one bel pin. Removing this old field is the first step towards developing a new API for this. Signed-off-by: gatecat <gatecat@ds0.me>

| | | | | | | | | | | | | | | | | | | | | | | | | | This makes the Arch API clearer and also allows a base implementation of functions to reduce the amount of complexity to get a basic Arch up and running. Currently this only implements these for functions that don't return a range. Range-returning functions will require more work in order due to the current 'duck typing' approach (probably a struct that contains the range types combined with templating.) Signed-off-by: D.
