Martin Povišer	481d596c43	abc9_ops -prep_box: Adjust for repeated invocation ... `abc9_ops -prep_box` command interprets the `abc9_box` attribute and prepares a .box file for ABC consumption. Previously this command was removing the attribute as it was processing each module which prevented repeated invocation of this command unless the box definitions were refreshed from a source file. Also the command was keeping existing `abc9_box_id` attributes instead of overwriting them with values from a new number sequence. Change both behaviors to allow repeated invocations of the command on the same design.	2024-12-05 18:32:41 +01:00

Krystine Sherwin	1de5d98ae2	Reduce comparisons of size_t and int ... `Const::size()` returns int, so change iterators that use it to `auto` instead of `size_t`. For cases where size is being explicitly cast to `int`, use the wrapper that we already have instead: `Yosys::GetSize()`.	2024-11-29 12:53:29 +13:00
