Robert O'Callahan 66d2c2af08 Make `log_header()` use variadic templates. 2025-09-09 15:41:03 +02:00
Robert O'Callahan d34ac0c87d Make `log()` use the `FmtString` infrastructure. 
Now `log()` supports `std::string`.

We have to fix a few places where the format parameter was not a compile time constant.
This is mostly trivial.

Jannis Harder 61a00b9131 memory_libmap: Fix use of uninitialized value for async read ports 
The code in memory_libmap expects `clk_en` to be initialized for all
`PortVariant`s but the parsing in memlib.cc didn't initialize it for
variants of kind `PortKind::Ar` (async read ports).

While this fixes the immediate CI failure, it would be best to refactor
the code so it becomes obvious if something isn't initialized.

Jannis Harder b6db32873d Add IdString const &id_string() const to StaticIdString and IdString 
The vast majority of ID(...) uses are in a context that is overloaded
for StaticIdString or will cause implicit conversion to an IdString
constant reference. For some sufficently overloaded contexts, implicit
conversion may fail, so it's useful to have a method to force obtaining
a `IdString const &` from an ID(...) use.

When turning all literal IdStrings of the codebase into StaticIdStrings
this was needed in exactly one place, for which this commit adds an
`id_string()` call.

Mohamed Gaber ae8c4e2ea6 libparse/filterlib: mark LibertyParser::error() as weak 
When FILTERLIB is defined (attempts to compile libparse more or less standalone,) mark the `LibertyParser::error()` as weak so utilities using libparse as a library can override its behavior (the default behavior being exit(1)). As the code is quite performance-critical, I've elected to not modify it to raise an exception or have a callback or similar and simply allow for a link-time replacement.

Robert O'Callahan 8c04e5266c Use commutative hashing instead of expensive allocation and sorting 
For one of our large circuits, this improves the `OptMergePass` runtime
from about 150s to about 130s. It's also simpler code.

Robert O'Callahan 3f2c4f6f83 Remove redundant construction of `assign_map`. 
We call 'assign_map.set()' below which wipes the `SigMap` and reconstructs it.

This operation is expensive because it scans the whole module. I think it's
better to make heavyweight operations more visible so I'm removing
the less obvious operation.
