Merge pull request #5591 from YosysHQ/krys/clean_empty_switch 
Improve handling of empty switches
 2026-01-09 11:52:27 +13:00
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 #5555 from rocallahan/defer-redirects 
Defer redirecting cell outputs when merging cells in `opt_merge` untill after we've done a full pass over the cells.

Robert O'Callahan 042ec1cf60 Defer redirecting cell outputs when merging cells in `opt_merge` until after we've done a full pass over the cells. 
This avoids changing `assign_map` and `initvals`, which are inputs to the hash function for `known_cells`,
while `known_cells` exists. Changing the hash function for a hashtable while it exists leads to
confusing behavior. That also means the exact behavior of `opt_merge` cannot be reproduced by a
parallel implementation.

Merge pull request #5550 from YosysHQ/nak/dont_merge_properties 2025-12-22 16:54:43 +01:00
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 53614a37a1 Use `Tcl_Size` instead of `int` to fix build errors 
Fixes these build errors I'm getting locally with `tcl-devel-9.0.0-7.fc42.x86_64`.
I guess Tcl 9 broke this.
