* Fitting help messages to 80 character widthKrystalDelusion2022-08-241-3/+3
| | | | | | | | | 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.

* synth_ice40: Use opt_dff.Marcelina Kościelnicka2020-07-302-247/+86
| | | | | | | | | The main part is converting ice40_dsp to recognize the new FF types created in opt_dff instead of trying to recognize the mux patterns on its own. The fsm call has been moved upwards because the passes cannot deal with $dffe/$sdff*, and other optimizations don't help it much anyway.

* Use [[maybe_unused]] instead of YS_ATTRIBUTE(unused).whitequark2020-06-191-10/+10
| | | | | [[maybe_unused]] is available since C++17, so this commit adds a polyfill YS_MAYBE_UNUSED. Once we require C++17 we can drop it.

* Makefile: don't assume python is called `python3`Sean Cross2019-10-191-2/+2
| | | | | | | | | | | | | | | | On some architectures, notably on Windows, the official name for the Python binary from python.org is `python`. The build system assumes that python is called `python3`, which breaks under this architecture. There is already infrastructure in place to determine the name of the Python binary when building PYOSYS. Since Python is now always required to build Yosys, enable this check universally which sets the `PYTHON_EXECUTABLE` variable. Then, reuse this variable in other Makefiles as necessary, rather than hardcoding `python3` everywhere. Signed-off-by: Sean Cross <sean@xobs.io>
