Robert O'Callahan 5ac6858f26 Remove .c_str() from log_cmd_error() and log_file_error() parameters 2025-09-16 22:59:08 +00:00
Robert O'Callahan e0ae7b7af4 Remove .c_str() calls from log()/log_error() 
There are some leftovers, but this is an easy regex-based approach that removes most of them.

cmdref: Assigning cmds to formal group 
Give formal index a proper title.
Use `Pass::formatted_help()` to assign the group, but still return `false` because the help text still comes from `Pass::help()`.
Tidy up some of the affected files' includes to make use of the shared `yosys.h` includes.

Emil J. Tywoniak 387a235158 functional, glift: use fold overload of IdString::in instead of pool literals 2024-11-06 12:48:32 +01:00
Rasmus Munk Larsen 0a37c2a301 Fix translation bug: The old code really checks for the presense of a node, not an edge in glift and flatten. 
Add back statement that inserts nodes in order in opt_expr.cc.

Rasmus Munk Larsen e0042bdff7 Speed up TopoSort. The main sorting algorithm implementation in TopoSort::sort_worker is 11-12x faster. Overall, the complete sequence of building the graph and sorting is about 2.5-3x faster. The overall impact in e.g. the replace_const_cells optimization pass is a ~25% speedup. End-to-end impact on our synthesis flow is about 3%. 2023-09-20 15:49:05 -07:00
KrystalDelusion 9465b2af95 Fitting help messages to 80 character width 
Uses the regex below to search (using vscode):
	^\t\tlog\("(.{10,}(?<!\\n)|.{81,}\\n)"\);

Finds any log messages double indented (which help messages are)
and checks if *either* there are is no newline character at the end,
*or* the number of characters before the newline is more than 80.

glift: Add `-simple-cost-model` option 
Rather than assigning specific weights to specific versions of taint tracking logic and summing the weights of all GLIFT cells, sum the following values for each GLIFT cell:
  - 0 if the associated hole/$anyconst cell value is non-zero, i.e. reduced-precision taint tracking logic is chosen at this cell
  - 1 if the associated hole/$anyconst cell value is zero, i.e. the full-precision taint tracking logic is chosen at this cell

This simplified cost modeling reduces the potential for the QBF-SAT solver to minimize taint tracking logic area but significantly simplifies the QBF-SAT problem.
