whitequark 6e559ee3c7 synth_ice40: split `map_gates` off `fine`. 2018-12-06 12:04:39 +00:00
whitequark d9fa4387c9 synth_ice40: add -noabc option, to use built-in LUT techmapping. 
This should be combined with -relut to get sensible results.

Henner Zeller 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)

Tim 'mithro' Ansell d6bdefd2e9 Improving vpr output support. 
* Support output BLIF for Xilinx architectures.
 * Support using .names in BLIF for Xilinx architectures.
 * Use the same `NO_LUT` define in both `synth_ice40` and
  `synth_xilinx`.
