abd9c51963 Speed up simplemap_map by 11.6x by directly inserting the cell source attribute in the new object's 'attributes' map instead of calling set_attr_pool to create a new pool and then copying that. Based on a suggestion by Martin Poviser in a comment on https://github.com/YosysHQ/yosys/pull/3959 2023-10-02 17:32:56 +01:00

7203ba7bc1 Add bitwise $bweqx and $bwmux cells 
The new bitwise case equality (`$bweqx`) and bitwise mux (`$bwmux`)
cells enable compact encoding and decoding of 3-valued logic signals
using multiple 2-valued signals.

661fa5ff92 simplemap: Map $xnor to $_XNOR_ cells 
The previous mapping to `$_XOR_` and `$_NOT_` predates the addition of
the `$_XNOR_` cell.

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.

4e70c30775 FfData: some refactoring. 
- FfData now keeps track of the module and underlying cell, if any (so
  calling emit on FfData created from a cell will replace the existing cell)
- FfData implementation is split off to its own .cc file for faster
  compilation
- the "flip FF data sense by inserting inverters in front and after"
  functionality that zinit uses is moved onto FfData class and beefed up
  to have dffsr support, to support more use cases

3aa4484a3c Consistent use of 'override' for virtual methods in derived classes. 
o Not all derived methods were marked 'override', but it is a great
  feature of C++11 that we should make use of.
o While at it: touched header files got a -*- c++ -*- for emacs to
  provide support for that language.
o use YS_OVERRIDE for all override keywords (though we should probably
  use the plain keyword going forward now that C++11 is established)
