| * Harmonize BRAM/LUTRAM descriptions across all of Yosys.whitequark2020-01-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit: * renames all remaining instances of "DRAM" (which is ambiguous) to "LUTRAM" (which is not), finishing the work started in the commit 698ab9be; * renames memory rule files to brams.txt/lutrams.txt; * adds/renames script labels map_bram/map_lutram; * extracts where necessary script labels map_ffram and map_gates; * adds where necessary options -nobram/-nolutram. The end result is that BRAM/LUTRAM/FFRAM aspects of every target are now consistent with each other. Per architecture: * anlogic: rename drams.txt→lutrams.txt, add -nolutram, add :map_lutram, :map_ffram, :map_gates * ecp5: rename bram.txt→brams.txt, lutram.txt→lutrams.txt * efinix: rename bram.txt→brams.txt, add -nobram, add :map_ffram, :map_gates * gowin: rename bram.txt→brams.txt, dram.txt→lutrams.txt, rename -nodram→-nolutram (-nodram still recognized), rename :bram→:map_bram, :dram→:map_lutram, add :map_ffram, :map_gates

* Consistent use of 'override' for virtual methods in derived classes.Henner Zeller2018-07-201-4/+4
| | | | | | | | | 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)
