Emil J. Tywoniak	01f332e750	opt_expr: reduce mostly harmless warning to log	2024-06-25 20:18:49 +02:00
Martin Povišer	fa4a2b6b0d	opt_expr: In clkinv loop ignore irrelevant cells early ... Each call to `handle_clkpol_celltype_swap` has a conversion of the cell's type ID to an allocated string. This can sum up to a non-negligible time being spent in the clkpol code even for a design which doesn't have any flip-flop gates.	2024-06-24 18:32:33 +02:00
Martin Povišer	7a8a69b65c	opt_expr: Revisit sorting in replace_const_cells ... Avoid building a cell-to-inbit map when sorting the cells, add a warning if we are unable to sort, and move the code treating non-combinational cells ahead of the rest (this means we don't need to pass non-combinational cells to the TopoSort object at all).	2024-06-24 18:32:33 +02:00

Emil J. Tywoniak	4bb3b099d2	opt_demorgan: fix extra args warning	2024-04-03 10:02:53 +02:00
Martin Povišer	030d639201	opt_mem, memory_*: Refuse to operate in presence of processes ... Processes can contain `MemWriteAction` entries which are invisible to most passes operating on memories but which will be lowered to write ports later on by `proc_memwr`. For that reason we can get corrupted RTLIL if we sequence the memory passes before `proc`. Address that by making the affected memory passes ignore modules with processes.	2024-02-23 12:27:53 +01:00
