Check for missing port in SDC code to work around compiler bug

Robert O'Callahan 37347aacb2 Check for missing port in SDC code 
I am getting weird crashes on `main` in `tests/sdc/alu_sub.ys` which I traced to a null `Wire*`
in `SdcObjects::constrained_ports`. The null `Wire*` is being set in the `SdcObjects`
constructor. I don't understand what's going on here, so I added this check to detect the
missing wire early ... and that made the crash go away. Compiler bug maybe? I have
`Debian clang version 19.1.7 (3+build5)`, default build configuration.

Anyway this code seems fine to have.

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.
 2026-01-06 18:48:16 +01:00
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.

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.
 2025-12-22 01:57:30 +00:00
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.

sim.cc: Check eval err 
Some cells (e.g. $macc_v2) are marked evaluable, but will raise an abort if called with `CellTypes::eval()`.
Instead of falling through to the abort, we can pass a pointer to a boolean to check for errors.
Use said check to catch `CellTypes::eval()` errors and treat them as unevaluable but otherwise continue.
Reflows the series of if checks into `if ... else if ... else` so that we can check for errors and set state in one place.

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.

This addresses https://github.com/YosysHQ/yosys/issues/2545, allowing Yosys to be better packaged in non-FHS environments such as Nix.
