Marcelina Kościelnicka d25b9088c8 Refactor common parts of SAT-using optimizations into a helper. 
This also aligns the functionality:

- in all cases, the onehot attribute is used to create appropriate
  constraints (previously, opt_dff didn't do it at all, and share
  created one-hot constraints based on $pmux presence alone, which
  is unsound)
- in all cases, shift and mul/div/pow cells are now skipped when
  importing the SAT problem (previously only memory_share did this)
  — this avoids creating clauses for hard cells that are unlikely
  to help with proving the UNSATness needed for optimization

Marcelina Kościelnicka ec2a468bd3 backend/verilog: Add alternate mode for transparent read port output. 
This mode will be used whenever read port cannot be handled in the
"extract address register" way, ie. whenever it has enable, reset,
init functionality or (in the future) mixed transparency mask.

Zachary Snow c016f6a423 proc_rmdead: use explicit pattern set when there are no wildcards 
If width of a case expression was large, explicit patterns could cause
the existing logic to take an extremely long time, or exhaust the
maximum size of the underlying set. For cases where all of the patterns
are fully defined and there are no constants in the case expression,
this change uses a simple set to track which patterns have been seen.

Marcelina Kościelnicka 436d42c00c opt_expr: Propagate constants to port connections. 
This adds one simple piece of functionality to opt_expr: when a cell
port is connected to a fully-constant signal (as determined by sigmap),
the port is reconnected directly to the constant value.  This is just
enough optimization to fix the "non-constant $meminit input" problem
without requiring a full opt_clean or a separate pass.

cxxrtl: escape colon in variable names in VCD writer
 2021-07-20 09:30:08 +00:00
whitequark fc84f23001 cxxrtl: escape colon in variable names in VCD writer. 
The following VCD file crashes GTKWave's VCD loader:

    $var wire 1 ! x:1 $end
    $enddefinitions $end

In practice, a colon can be a part of a variable name that is
translated from a Verilog function, something like:

    update$func$.../hdl/hazard3_csr.v:350$2534.$result
