Robert O'Callahan 8da919587d Parallelize `opt_merge`. 
I'm not sure why but this is actually faster than existing `opt_merge` even with
YOSYS_MAX_THREADS=1, for the jpeg synthesis test. 16.0s before, 15.5s after for
end-to-end synthesis.

Merge pull request #5564 from rocallahan/pass-fuzz

Robert O'Callahan a6d696ba2b Give `IdString` a default move constructor and make it a POD type. 
Now that we're not refcounting `IdString`, it can use the default move constructor.
This lets us make `IdString` a POD type so it can be passed in registers
in the standard C++ ABI.

Robert O'Callahan 48cdb499f2 Remove `IdString::id_string()`. 
This was needed for the short time when `ID()` could return a value of `StaticIdString`.
That is no longer a problem.

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.
