| * | | Fix typographical and grammatical errors and inconsistencies. | whitequark | 2019-01-02 | 1 | -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. | |||||
| * | Bugfix in opt_expr handling of a<0 and a>=0 | Clifford Wolf | 2018-12-06 | 1 | -1/+1 | |

| * | Consistent use of 'override' for virtual methods in derived classes. | Henner Zeller | 2018-07-20 | 1 | -2/+2 | |
| | | | | | | | | | | 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) | |||||

| | | | | | | | Add check for whether the high bit in the constant expression is greater than the width of the variable, and optimizes that to a constant 1 or 0 | |||||
