misc: `WITH_PYTHON` -> `YOSYS_ENABLE_PYTHON` 
For consistency.

Also trying a new thing: only rebuilding objects that use the pybind11 library. The idea is these are the only objects that include the Python/pybind headers and thus the only ones that depend on the Python ABI in any capacity, so other objects can be reused across wheel builds. This has the potential to cut down build times.

Jannis Harder 86fb2f16f7 bufnorm: Refactor and fix incremental bufNormalize 
This fixes some edge cases the previous version didn't handle properly
by simplifying the logic of determining directly driven wires and
representatives to use as buffer inputs.

Robert O'Callahan effc52fedc Make `ID::` constants be `StaticIdString`s for better optimization. 
Their internal indexes will be known at compile time, like we already support for the `ID()` macro.

Jannis Harder d88d6fce87 kernel: Rewrite bufNormalize 
This is a complete rewrite of the RTLIL-kernel-side bufnorm code. This
is done to support inout ports and undirected connections as well as to
allow removal of cells while in bufnorm mode.

This doesn't yet update the (experimental) `bufnorm` pass, so to
manually test the new kernel functionality, it is important to only use
`bufnorm -update` and `bufnorm -reset` which rely entirely on the kernel
functionality. Other modes of the `bufnorm` pass may still fail in the
presence of inout ports or undirected connections.

rhanqtl 11b829ba70 fix(parse): #5234 adjust width of rhs according to lhs 2025-09-16 15:24:23 +02:00
Robert O'Callahan fee2b8992c Stop using `mutable` in `Const`. 
Now that we only call `bitvectorize()` in non-const methods, we can move the casting-away-const to only happen
in `bitvectorize()`, which is deprecated so only some plugins (maybe) are using it.

This means `const` `Const` methods don't change the underlying data, which means
they'll be safe to use from multiple threads if/when we want to do that.

Jannis Harder 3ebecb631c Add a compile time check that kernel/constids.inc is sorted 
This is an invariant now required by the ID macro, so it's better to
have an actual check and not rely on a comment at the top of
kernel/constids.inc.

test_cell: Support more cell types 
Still unsupported:
- wide muxes (`$_MUX16_` and friends)

Partially supported types have comments in `test_cell.cc`.

Fix `CellTypes::eval() for `$_NMUX_`.
Fix `RTLIL::Cell::fixup_parameters()` for $concat, $bwmux and $bweqx.
