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 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.

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.
