* Mark IdString and IdStringList single argument constructors explicit.Keith Rothman2021-02-0416-86/+93
| | | | | | | | | Single argument constructors will silently convert to that type. This is typically not the right thing to do. For example, the nexus and ice40 arch_pybindings.h files were incorrectly parsing bel name strings, etc. Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>

| * Use a LRU cache for pip to wire map.Keith Rothman2021-02-031-10/+113
|/ | | | | | | | This avoids storing the entire pip to wire map in memory with a moderate runtime increase and a dramatic memory decrease (2 GB to 200 MB for A50T). Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>

| * Refactor GUI to use IdStringListsD. Shah2021-02-024-51/+50
| | | | | | | | | | | | | | | | The GUI internally had an 'IdStringList' type that I hadn't spotted, to avoid a conflict this is renamed to IdList which also reflects its new purpose better. Signed-off-by: D. Shah <dave@ds0.me>
| * ecp5: Implement IdStringList for all arch object namesD. Shah2021-02-027-93/+121
| | | | | | | | | | | | | | This is a complete implementation of IdStringList for ECP5; excluding the GUI (which you will have to disable for it to build). Signed-off-by: D. Shah <dave@ds0.me>

| * ecp5: Proof-of-concept using IdStringList for bel namesD. Shah2021-02-0212-61/+101
| | | | | | | | | | | | | | | | | | | | | | This uses the new IdStringList API to store bel names for the ECP5. Note that other arches and the GUI do not yet build with this proof-of-concept patch. getBelByName still uses the old implementation and could be more efficiently implemented with further development.
