45017e19ec Make SigSpec::unpack() non-const 2025-10-31 11:53:39 +00:00
Robert O'Callahan
9a2fd4c31b Switch the SigSpec packed representation to allow just a single chunk that's inline in the SigSpec. 
Single-chunk SigSpecs are very common and this avoids a heap allocation. It also simplifies
some algorithms.

be530bef73 Instead of using packing and hashing to compute SigSpec ordering and equality, just use the width and chunkwise comparisons 
This avoids having to pack and compute hashes, and generally results in a
simpler ordering.

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.

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.

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.

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.
