Robert O'Callahan	7e75200b2a	Check that we don't use logging during multithreading	2025-11-29 22:47:23 +00:00
Robert O'Callahan	b23dc345ae	Make it safe to access .c_str() for autoidx IDs in a multithreaded context	2025-11-25 22:49:41 +00:00
Robert O'Callahan	948001f39f	Merge the two autoidx hashtables into one ... When something calls `IdString::c_str()` on an autoidx ID, we need to cache the full string in a thread-safe way. If we need to allocate an entry in some data structure to do that, it's difficult to do in a thread-safe no-performance-hazard way. So instead, store the cached string pointer in the same hashtable as the prefix pointer.	2025-11-25 21:57:46 +00:00
Robert O'Callahan	8f0ecce53f	Forbid creating IdStrings and incrementing autoidx during multithreaded phases, and add dynamic checks for that ... We could make it safe to increment autoidx during multithreaded passes, but that's actually undesirable because it would lead to nondeterminism. If/when we need new IDs during parallel passes, we'll have to figure out how to allocate them in a deterministic way, and that will depend on the details of what the pass does. So don't try to tackle that now.	2025-11-25 21:57:46 +00:00
Robert O'Callahan	4c8b537d71	Remove YOSYS_NO_IDS_REFCNT ... Refcounting is hardly used at all so this option is not that useful. We might want to have a different option that disables GC if that becomes a performance issue, but that should be a different option.	2025-11-25 21:57:46 +00:00
Robert O'Callahan	7f9de6e48f	Make coverage data thread-safe	2025-11-25 21:46:48 +00:00
Krystine Sherwin	bc310e7165	Celltypes: Revert c++20 feature ... Turns out using designated initializers is c++20, so not available while we are still c++17 friendly.	2025-11-22 16:24:57 +13:00
Krystine Sherwin	155bc8b14e	celltypes: Reword synthesizable comment ... Don't mention verilog.	2025-11-22 16:24:56 +13:00
Krystine Sherwin	8badbf75c4	celltypes: Add help -celltypes ... Like `help -cells` but instead of printing the cell's ports, prints its flags.	2025-11-22 16:24:56 +13:00
Krystine Sherwin	b48881e996	celltypes: Extra type props ... Now with `is_internal`, `is_metainfo`, and `has_effects`. Each type property has a comment specifying usage/meaning. Type properties (sans `is_internal`) get a default value of false. `CellTypes::setup_*_type()` methods get their own `CellType` struct assignments with named fields being assigned true to improve readability. Also remove is_evaluable from cell types that aren't actually eval-able, instead using is_combinatorial which afaict is what the flag was being used as a proxy for.	2025-11-22 16:24:55 +13:00
Krystine Sherwin	542a547c78	celltypes: get_cell() helper ... Add `CellTypes::get_cell()` which takes a 'type' `IdString` and returns the corresponding `CellType` if it is in the `cell_types` dict, otherwise returns `nullptr`. Useful for getting a cell type by name and then checking its attributes.	2025-11-22 15:57:34 +13:00
Krystine Sherwin	04092ea93d	celltypes: Add and use setup_type helpers ... Add `CellTypes::setup_{comb, ff, formal}_type()`. Most of the existing internal cells fit into one of these three groups.	2025-11-22 15:55:18 +13:00

Robert O'Callahan	b0e2d75dbe	Make IdString refcounts a hashtable containing only the nonzero refcounts ... This saves space and doesn't cost very much since we hardly ever have nonzero refcounts any more. It also allows for IdStrings with negative indexes, which we're going to add.	2025-11-12 11:52:04 +01:00
