* Fix typographical and grammatical errors and inconsistencies.whitequark2019-01-021-1/+1
| | | | | | | | | | | | The initial list of hits was generated with the codespell command below, and each hit was evaluated and fixed manually while taking context into consideration. DIRS="kernel/ frontends/ backends/ passes/ techlibs/" DIRS="${DIRS} libs/ezsat/ libs/subcircuit" codespell $DIRS -S *.o -L upto,iff,thru,synopsys,uint More hits were found by looking through comments and strings manually.
* Consistent use of 'override' for virtual methods in derived classes.Henner Zeller2018-07-202-6/+6
| | | | | | | | | 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)
