Robert O'Callahan dcd7742d52 Avoid scanning entire module if there are no wires to remove 
It's pretty common for `opt_clean` to find no wires to remove. In that case,
there is no point scanning the entire design, which can be significantly
expensive for huge designs.

Robert O'Callahan 46cb05c471 Pass IdString by value instead of by const reference. 
When IdString refcounting was expensive, it made sense to pass it by const reference
instead of by value, to avoid refcount churn. Now that IdString is not refcounted,
it's slightly more efficient to pass it by value.

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.

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.

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.

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.
