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 261a0ae9e1 Implement at() methods on SigSpec so that SigSpec::bits().at() continues to work as it did
Fixes a regression caused by commit 745222fa3b, which caused some
third-party code to fail to build, e.g.:
5d7aa035c6/lib/Transforms/YosysOptimizer/RTLILImporter.cpp (L229)

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.
